A behaviour a workflow adds is exercised there: a new check runs +on the example portal, a new failure message is reached by something the example can do. The +example portal's own Python follows +[`docs/contributing/standards/testing.md`](docs/contributing/standards/testing.md). + +### Article II — Simplicity +Start with the simplest workflow that serves the portals that exist. A new workflow, job, input +or third-party action each needs a stated reason in the pull request that adds it. + +### Article III — Anti-Abstraction +No input, composite action or indirection for a portal that does not exist yet. A step repeated in +several workflows stays repeated while GitHub offers no way to share it within one tag of this +repository, and every copy changes in the same pull request. + +### Article IV — Integration-First +The caller workflow is the contract. A change is designed from what a portal writes and sees: the +caller file, the secrets it passes, the check names its ruleset requires, and what it must +provide. It is verified the way a portal uses it, through a caller on the example portal. + +### Article V — Security & data-safety +These workflows run in other organisations' repositories with their secrets, so this repository +is part of every portal's supply chain. +- Secrets are declared under `on.workflow_call.secrets` and passed by name. `secrets: inherit` is + never relied on. +- Each workflow and job asks for the fewest permissions it needs. Checkouts set + `persist-credentials: false` unless a later step pushes. +- Third-party actions are pinned to a release tag. A new third-party action needs a stated reason. +- A value read from a file or an event reaches a shell through an environment variable, never + through `${{ }}` inside a `run` script, unless it has been checked against a strict pattern. +- Changes to tokens, permissions or secrets never take a shortened review path. + +### Article VI — Documentation +Every reusable workflow, its inputs and secrets, the checks it reports and what it requires of a +portal are documented in the README, and recorded in `CHANGELOG.md`, in the same pull request that +changes them. Comments in workflow files say why, not what, following +[`docs/contributing/standards/code-documentation.md`](docs/contributing/standards/code-documentation.md). +The README follows [`docs/contributing/standards/documentation.md`](docs/contributing/standards/documentation.md) +where it applies to a single-page README. + +### Article VII — Dependency discipline +The actions the workflows use are dependencies of every portal. Dependabot proposes their updates, +and an update merges only after the example portal has passed every workflow with it. The example +portal pins FairDM to a release or a commit on FairDM's default branch, and moves it on purpose. + +## Project articles + +### Article VIII — One kind of caller +Every workflow serves portals and nothing else, and does the same thing for every portal. No input +switches a workflow's behaviour for a particular portal. A repository that does not fit writes its +own workflow. The one input, `working-directory`, exists so the example portal can live in a +subdirectory; portals leave it unset. + +### Article IX — The platform comes from FairDM +The base image version and PostGIS version a workflow uses are read from the +`[tool.fairdm.platform]` table of the FairDM the portal pins in `uv.lock`. A workflow never names +one itself and never takes one as an input. When it cannot read them it fails, saying why. + +### Article X — Interface stability +The interface is: the reusable workflow file names, their inputs and secrets, the names of the +checks they report, the permissions a caller must grant, and what a portal must provide. Before +1.0 a minor release may break it, and the release says what a portal changes. From 1.0, breaking it +needs a major release. + +### Article XI — Tag and release discipline +Portals pin a tag, never `main`. A tag is never moved or deleted once published. A change reaches a +portal only through a new tag and a pull request in that portal. + +## Articles not adopted + +This repository ships no Django application. The example portal is a few lines of configuration +with no models, strings or behaviour of its own. These articles have no subject here, and become +live if that changes: + +- Internationalization +- Data-model conventions (Django) +- Cohesion (Python) + +[`docs/contributing/standards/django.md`](docs/contributing/standards/django.md) is kept with the +other standards for the example portal's few Django files. + +## Quality bar + +Read at plan and review. Applies to every change. +- `Lint Workflows` passes: actionlint and the workflow schema are clean. +- Every reusable workflow passes on the example portal. +- A change to the interface (Article X) updates the README and `CHANGELOG.md` in the same pull + request, and the README's caller examples still work as written. +- The `Platform` job is identical in every workflow that has one. + +## Non-negotiables + +- The validation checks pass before a change merges. Nobody overrides a red check. +- The default branch requires one approval, and the author of a change never approves it. +- Dependabot auto-merge is permitted only while the ruleset requires the example portal's checks. + +--- + +**Version**: 1.0.0 | **Ratified**: 2026-10-19 | **Last Amended**: 2026-10-19 diff --git a/CONTEXT.md b/CONTEXT.md new file mode 100644 index 0000000..fa73fe6 --- /dev/null +++ b/CONTEXT.md @@ -0,0 +1,32 @@ +# CONTEXT.md — Domain glossary + +The vocabulary of this repository.

Ask +what abstraction to create only when that question has no answer. A change is right when a +Django developer who has never seen this repository can find it by following the framework's +conventions and the ones this repository has already set. + +## 1. Where code lives + +| The code is | It lives in | Never in | +|---|---|---| +| A rule about one record, or something a record does | A method or property on the model | A view, a form's `save()`, a free function taking the instance | +| A rule that must hold for every row, and that the database can express | `Meta.constraints` | `clean()` alone | +| A query used in more than one place | A method on the model's `QuerySet` | A view, a template tag | +| Checking and converting what a user submitted | A `Form` or `ModelForm` | The view body | +| Reading the request, checking access, choosing the response | The view | A model or a form | +| How a value is shown | The template, or a template tag or filter when reused | A model method that returns HTML | +| An operation across several models | A method on the model the operation is named after (section 2) | A view, a signal | +| Something run from the command line or a scheduler | A management command that calls the model or queryset | Logic written in the command itself | + +Dependencies point one way: models, then forms, then views, then templates. A model never imports +a form or a view. A form never imports a view. + +### Modules + +Code lives in the modules a Django developer already knows: `models.py`, `managers.py`, +`forms.py`, `views.py`, `urls.py`, `admin.py`, `apps.py`, `signals.py`, `templatetags/`, +`management/commands/`. Look there first. + +**Code that fits none of them goes in `utils.py`.** That is where a Django developer looks for +standalone helper functions, so it is the default. It is not a way around the table above: code +that belongs on a model, a queryset or a form still goes there. + +**When `utils.py` grows too large, it becomes a `utils/` package**, with one submodule per group +of related functions: `utils/dates.py`, `utils/text.py`. + +**A module of its own is for code with a defined character**: it has one clear subject, and it +is likely to be added to or extended. `menus.py` holds the app's menus. `importing.py` holds its +importer. The name states the scope plainly enough that a reader knows what is inside without +opening it. + +## 2. Models + +- **Behaviour goes on the model it concerns.** `invoice.mark_paid()`, never + `mark_invoice_paid(invoice)` in another module. +- **`save()` does not validate.** `clean()`, field validators and `choices` run only through + `full_clean()`, which a `ModelForm` calls and `save()`, `create()`, `update()` and + `bulk_create()` do not. A rule that must hold however the row is written is a database + constraint where the database can express it. Where it cannot, as with a rule that spans + tables, the rule lives in the one model method every write goes through. A rule that only + shapes what a person may enter is validation. +- **An operation across several models belongs to the model it is named after.** Publishing a + vocabulary freezes its concepts, so it is `Vocabulary.publish()`. A bulk operation is a + `QuerySet` method. +- **When no model owns the operation**, it goes in `utils.py`, or in a module of its own when it + has a clear subject and is likely to be extended (section 1, Modules). +- **Override `save()` and `delete()` only for what must happen on every write of that model.** + Neither runs for `QuerySet.update()`, `bulk_create()` or a cascade delete, so nothing that must + always hold may depend on them. + +## 3. Queries + +- **A reusable query is a `QuerySet` method**, exposed with `Manager.from_queryset()` or + `QuerySet.as_manager()`. Write the method on the queryset, never on the manager alone, so that + it chains. +- **Methods are small and compose.** `Concept.objects.published().in_scheme(scheme)`, never one + `get_published_concepts_for_scheme()`. +- **The second use moves a query.** A filter written once stays in the view that needs it. The + same `filter`, `exclude` or `annotate` chain appearing a second time becomes a method. +- **Database work is visible at the call site.** A property or template tag that runs a query on + every access hides an N+1 problem. Load related rows with `select_related`, `prefetch_related` + or an annotation in the queryset the view builds. +- **Compute in the database when the result is used to filter, order or count.** Use an + annotation or aggregate. A Python loop over a queryset is for work the database cannot do. + +## 4. Forms + +- **Input that has to be checked or converted goes through a form.** A view never validates + `request.POST` or `request.GET` by hand. A search term or page number read straight from the + query string, and a button that posts no fields, need no form. +- **A form checks what was entered: format, required fields, how fields relate.** A rule that + holds without a form is a model rule (section 2). Do not repeat a model's validators on its + form, because a `ModelForm` already runs them. +- **A form's `save()` saves.** Anything more is a model method that `save()` or the view calls. + +## 5. Views + +- **Class-based views are strongly preferred**, built on Django's generic views or the + repository's own base views. This is a house preference, not a claim about Django: our + packages publish their views for projects to subclass, and a function cannot be subclassed. A + function view is fine for a small endpoint nobody will extend, such as a webhook or a health + check. +- **A view deals with the request and the response:** who is asking, what they sent, which model + or queryset method to call, what to send back, and what the template needs. +- **Use the hooks the generic view already has:** `get_queryset`, `get_form_kwargs`, + `form_valid`, `get_context_data`, `get_success_url`. Do not override `get`, `post` or + `dispatch` to do what a hook does. +- **A view method that makes a decision about the data is in the wrong place.** Move the decision + to the model and call it. +- **Access control uses Django's mechanisms:** `LoginRequiredMixin`, `PermissionRequiredMixin`, + `UserPassesTestMixin`, and for access to one record, a queryset already limited to what the + user may see. + +## 6. Templates + +- **A template shows what it is given.** It may branch and loop on that data. It does not + compute, filter querysets, or decide who may do what beyond calling `perms` or a flag the view + set. +- **Reused presentation logic is a template tag or filter.** A value that needs several steps to + work out is worked out in the view or on the model. +- **Content is added to a page by template inheritance:** extend the template and fill a block, + with `{{ block.super }}` to keep what was there. Where the repository already has its own way + to add content, such as a menu class or a plugin, use that. +- **In a repository that uses django-cotton, a reused piece of template is a component**, never + an `{% include %}` partial. + +## 7. Transactions, side effects and signals + +- **A change that writes more than one row is atomic.** Wrap the whole operation in + `transaction.atomic()` at the method that owns it (section 2), not around each step inside it. +- **Anything that leaves the database waits for the commit.** Emails, task queues and calls to + other systems go in `transaction.on_commit()`. +- **If the operation is wrong without a step, the step is called by name.** Never from a signal. +- **A signal is for code that must not know about the sender:** reacting to another app's model, + or letting other apps react to yours. Inside one app, call the method. Receivers live in + `signals.py` and are connected in `AppConfig.ready()`. + +## 8. Abstractions + +Many of our packages exist to give developers a higher-level interface to Django: menu classes, +a registry that models are registered with, a plugin system, base views. Those abstractions are +the product. This section separates them from the plumbing a change adds for its own +convenience. + +### What the repository already provides + +- **Work with it, in its own style.** A new menu is a subclass of the menu class. A new model is + registered the way the others are. A new plugin follows the existing plugins. Section 1 does + not override this: where the repository has its own way to do something, that way is the + convention. +- **Extend it when the work calls for it.** Adding an option, a hook or a subclass to an existing + abstraction is ordinary work and needs no special justification. +- **Do not rewrite or remove it because of this document.** If an existing abstraction looks + wrong, raise an issue. Replacing it is a design decision for the maintainers, never a side + effect of another change. + +### A new interface for developers + +- **It is asked for, not discovered.** A new public abstraction comes from the specification or + issue the work is done under. If the work seems to need one that nobody asked for, stop and + ask. +- **It looks like Django.** Model it on an interface Django developers already use: a class with + declarative attributes like `ModelAdmin`, registration like `admin.site.register`, discovery + like `autodiscover`, options in an inner `Meta`. A developer should be able to guess how it + works from knowing Django. +- **It can be followed.** Someone reading a subclass can find the base class, see which + attributes and methods it reads, and work out what happens. Prefer plain classes and explicit + registration to machinery that generates code or settings. + +### Plumbing inside a change + +These apply to code no downstream developer will touch. + +- **Django's own mechanisms come first:** `Model`, `QuerySet`, `Form`, class-based views, template + tags, middleware, management commands, `AppConfig`. Reach for something else when one of these + was considered and could not do the job. +- **Patterns from other frameworks need a reason Django cannot answer:** service layers, + repositories, data transfer objects, use cases, command or event buses.

Leave it alone when two places only look alike. +- **A mixin is one behaviour with a name**, such as `OwnerRequiredMixin`, not a place to collect + helpers. A base class, mixin or helper waits for its second use. +- **A setting exists only when the code cannot know the value itself.** A sensible default with + no setting is better than a setting nobody changes. + +## 9. Apps + +- **An app is one area of the domain** and holds everything that area needs: its models, forms, + views, templates and tests. Apps are never split by technical layer. +- **Another app is used through what it publishes:** its models and their methods, its querysets, + its forms, its URL names, its template blocks. Never through its view internals or helper + modules. +- **Imports between apps run one way where they can.** Two apps that import each other's models + are usually one app. +- **Refer to a swappable model through its setting** (`settings.AUTH_USER_MODEL`), and to another + app's model by string (`"vocabularies.Concept"`) when importing it would be circular. + +## 10. Guidelines, not fixed rules + +Everything above is a guideline. Every situation is different, and an exception can be made +wherever it can be justified. + +- **The default holds until there is a reason.** "Never" in this document means "not without + one". +- **The reason is written down** where a reviewer will see it: in the pull request, or in a short + comment when the code would otherwise look like a mistake. +- **A reason is about this code:** what the usual place could not do, or why the reader is better + served here. Habit from another framework is not a reason. +- **Review checks the reasoning, not the letter.** A finding names the guideline and says why the + exception does not hold. + +Query counts and migration completeness are the two parts that are tested, as described in +[`testing.md`](testing.md), section 5. + +## Project additions + + + +--- + +**Version**: 1.0.0 diff --git a/docs/contributing/standards/documentation.md b/docs/contributing/standards/documentation.md new file mode 100644 index 0000000..f747bd6 --- /dev/null +++ b/docs/contributing/standards/documentation.md @@ -0,0 +1,188 @@ +# Documentation standards + +These rules cover the documentation a person reads to use what this repository makes: the pages +under `docs/` and the quickstart in the README. `CONSTITUTION.md` makes them binding.

An explanation, for example, can point to the decision +record behind a design. + +## 2. The four types + +Every page is one of four types, and only one. + +| Type | The reader | Answers | +|---|---|---| +| Tutorial | Is new, and learning by doing | Show me how to get started | +| How-to guide | Already uses it, and has a job to do | How do I do this one thing? | +| Reference | Is working, and needs a fact | What exactly is this setting, component or command? | +| Explanation | Is stepping back to understand | Why does it work this way? | + +Two questions tell the types apart: + +- **Does the page guide an action, or inform understanding?** Tutorials and how-to guides guide + action. Reference and explanation inform. +- **Is the reader learning, or working?** Tutorials and explanation serve learning. How-to + guides and reference serve work. + +Material of a second type goes on a second page, and the two link to each other. A how-to guide +that stops to explain a design, or a reference page that walks through a task, has two pages in +it. + +## 3. Where pages live + +```text +docs/ +├── index.md +├── tutorial.md +├── how-to/ +├── reference/ +└── explanation/ +``` + +- **`index.md`** says in one paragraph what the package is for, then lists the pages under one + heading for each type, in the order Tutorial, How-to guides, Reference, Explanation. The + maintainers' material from section 1 follows under headings of its own. +- **A tutorial longer than one page** becomes a `tutorial/` directory, its pages numbered in + the order they are read. +- **A file is named after its title**, in lowercase words joined by hyphens, with "How to" left + off: `how-to/add-a-menu-item.md`, `reference/settings.md`, + `explanation/how-a-theme-is-applied.md`. + +**A small package needs no `docs/` directory.** When setting the package up takes no more than +two short examples, the quickstart in the README is its tutorial and the README is its +documentation. A package that needs more than that has a `docs/` directory laid out as above, +and the README's quickstart links to the tutorial there. + +**An application's user guide is organised by the application's own sections**, not by type, +because a person looks for help under the name of the screen they are on. Each page is still one +type, and its title follows the rule for that type. Where the guide lives and how its contents are +ordered is set out in **Project additions**. + +## 4. Tutorials + +A tutorial takes someone new from nothing to a working result. + +- **Title**: what the reader will have built, such as "Build your first page". +- **Before you start**: what the reader needs, with a link for each. +- **One path.** No options, no alternatives and no "you could also". Choices belong in how-to + guides. +- **Every step ends with something the reader can see**: a page that loads, a command's output, + a test that passes. +- **The code is complete.** Each block can be copied as it stands, with its imports. A name the + reader must change, such as `yourproject`, is called out the first time it appears. +- **It explains almost nothing.** One sentence at most, then a link to the explanation. +- **It ends with the finished result**, and links to the how-to guides a reader is likely to + want next. + +A tutorial is followed from start to finish, in a new project, before a release that changes +anything it relies on. + +## 5. How-to guides + +A how-to guide takes someone who already uses the package through one task. + +- **Title**: "How to", then a verb, then what it acts on: "How to add a menu item", "How to + restrict a field to part of a vocabulary". +- **Opening paragraph**, with no heading: what the task achieves and when someone would do it, + in two sentences at most. +- **Before you start**: only when the task has a real precondition. Left out otherwise. +- **Steps**: one numbered list, one action to a step. Code in a step shows only what that step + changes, with enough around it to show where it goes. +- **The result**: what the reader sees once the task is done, and anything that changed + elsewhere. + +A how-to guide covers one task. A second task gets a guide of its own. It does not teach the +basics, which the tutorial covers, or explain the design, which the explanation covers. Every +setting, component or command it uses links to its reference entry. + +**Troubleshooting is a set of how-to guides.** Each entry is headed by the symptom the reader +sees, gives the cause in one sentence, then the fix. + +## 6. Reference + +A reference page describes the machinery: settings, components, template tags, management +commands, views, models and the Python API. + +- **It describes, and does nothing else.** No steps and no argument. A short example is fine + where it shows the usage faster than the prose can. +- **It is built like the thing it describes.** One page for the settings, one for the + components, one for the template tags, each in the order the code defines them or in + alphabetical order. +- **Every entry gives the same facts in the same order**: the name, its type or signature, its + default, what it does, and what it accepts. +- **It is complete.** Every public setting, component, tag and command has an entry. One that is + missing is a defect. + +**The Python API is generated from docstrings** wherever the repository builds its +documentation, and [`code-documentation.md`](code-documentation.md) makes those docstrings +complete. A docstring is never restated by hand on a reference page. A repository without a docs +build writes reference pages only for what a user sets or calls from outside Python: settings, +components, template tags and management commands. + +**An application's reference is a screen guide**: one page for each screen, titled with the +screen's own heading. It says what the screen is for and how to reach it, then has one section +for each part of the screen, saying what the part shows and what it shows when empty. It closes +with what the reader can do from the screen, each action a link to its how-to guide. + +## 7. Explanation + +An explanation helps a reader understand a subject. + +- **Title**: the subject, not a question: "How a theme is applied", "Concepts, schemes and + collections". +- **Opening paragraph**, with no heading: what the page covers and what it does not. +- **Body**: one idea to a section. Why the design is the way it is, what it was weighed against, + and where its limits are. +- **Decisions link to their record.** Where a decision has an entry in `docs/adr/`, the + explanation gives the reasoning in a form a user can follow and links to the record. + +An explanation never takes the reader through a task and never lists settings. A sequence that +describes how something works is fine. A list of things to do is a how-to guide. + +## 8. Every page + +- **It reads on its own.** A reader arrives from search or from a link, so the opening says what + the page covers. +- **It speaks to the reader as "you".** +- **It links rather than repeats.** A setting is described once, on its reference page, and + linked from everywhere else. +- **It describes the current release.** What changed, and when, is in the changelog. A page has + no "new in" notes and no record of how it used to work. + +## 9. Enforcement + +- Where the repository builds its documentation, the build treats warnings as errors, so a page + left out of the contents or a broken cross-reference fails it. +- Everything else, including that each page is one type, is checked in review. + +## Project additions + + + +--- + +**Version**: 1.0.0 diff --git a/docs/contributing/standards/testing.md b/docs/contributing/standards/testing.md new file mode 100644 index 0000000..ee05319 --- /dev/null +++ b/docs/contributing/standards/testing.md @@ -0,0 +1,166 @@ +# Testing standards + +These rules apply to every change in this repository. `CONSTITUTION.md` makes them binding. The +sections above **Project additions** are shared unchanged with our other repositories, so edit +this repository's rules in that last section only. + +## 1. What gets a test + +A test exists to catch a behaviour that breaks by accident. Before writing one, ask what decides +whether the result is right. + +- **A specification, a contract or a computation decides it.** Write a test. +- **Only a person looking at the page decides it.** Write no test. Make the change and have it + reviewed by eye. + +A useful second check is whether the test could fail for any reason other than someone +deliberately changing the value it asserts. If it could not, it is a change detector. It only +records a decision, and it has to be edited every time that decision changes. Do not write it. + +### Tested + +- The right records, values and fields appear, and the wrong ones do not. +- Conditional states: empty, absent, hidden from users without permission. +- Link and redirect targets. +- Form behaviour: validation, what is saved, where the user is sent afterwards. +- Values computed from data, including how a missing value is shown (`—` rather than `0`). +- Escaping of user and model data. +- Ids, `data-` attributes and other hooks that a script depends on. +- Permissions and access control. +- Query counts on list and detail pages (section 5). + +### Not tested + +- Wording: headings, labels, captions, help text, button text, empty-state text. +- Styling and layout: colours, widths, spacing, stacking, alignment, icons, component variants, + the order of sections on a page. +- CSS classes in project templates. + +### Markup that consumers depend on + +A package that publishes template components has consumers who write their own CSS and templates +against the markup those components emit. For a published component, that markup is behaviour: + +- the element it renders, +- the classes that make up the component's styling, +- the attributes and slots a caller can pass in. + +Decorative choices inside the component stay untested. In a project, all markup is design. + +### Text + +Text is behaviour only when it is computed from data: pluralised, formatted, or chosen by a +condition. Fixed wording is never asserted. + +Messages that do a job are tested for the job, not the sentence: + +- A validation error is asserted by the field it is attached to and its error code + (`form.has_error("date", code="future_date")`). Raise every `ValidationError` with a `code`. +- A flash message is asserted by its level and that it was added. +- An email is asserted by its recipient and the data or link it carries. + +### Finding elements + +A test that needs an element finds it by data from its fixtures, by role, or by id, never by the +surrounding wording. Renaming a heading must not break a behaviour test. When an existing test is +anchored on text that changes, update the string and nothing else. + +### Specifications + +An acceptance criterion states behaviour, never wording or appearance. "Shows the record's +licence" is a criterion. "Headed 'Licence'" is not, because a criterion is the thing a test is +written against. + +## 2. Test-first + +Every behaviour change follows the red, green, refactor cycle. + +1. **Red.** Write a test and watch it fail for the right reason. A test that passes on its first + run is testing nothing new. +2. **Green.** Write the least code that makes it pass. +3. **Refactor.** Clean up with the tests still green. A refactor that needs an assertion edited + has changed behaviour and is not a refactor. + +**Defects are reproduced first.** Write a test that fails with the reported symptom, then fix it. +If no test can reproduce it, say so in the pull request. + +**Changes to wording or appearance skip the cycle.** They are not defects. Make the change and +move on. + +Never weaken an assertion, add `skip` or `xfail`, broaden an `except`, or special-case production +code to make a test pass. + +## 3. Writing tests + +- **Assert outcomes, not call sequences.** `assert response.context["concepts"] == [...]` + survives a refactor. `mock_filter.assert_called_with(...)` breaks on one that changed nothing. +- **Real objects over fakes, fakes over mocks.** Mock only what is slow, non-deterministic or has + side effects outside the test: network calls, email, the clock. Never mock the ORM. +- **One behaviour per test**, named for it: `test_publishing_a_vocabulary_freezes_its_concepts`, + never `test_publish_works`. +- **Arrange, act, assert**, visibly separated, in that order. +- **Readable over DRY.** A test should read as a specification without tracing helpers. + +## 4. Structure and fixtures + +- **Mirror the source tree.** Every test module mirrors the path of the module it exercises: + `pkg/models.py` → `tests/test_models.py`, `pkg/views/form_views.py` → + `tests/test_views/test_form_views.py`. Test subpackages carry `__init__.py`. One source module + that defines several units stays one test module, split by classes. + + A test whose subject is not a Python module has nothing to mirror: + - `tests/test_factories.py` tests `tests/factories.py`. + - `tests/test_smoke.py` checks that the package imports and its settings are valid. + - A suite testing templates or static assets is exempt when the repository declares it: + + ```toml + [tool.forge.conformance] + non-mirror-paths = ["tests/test_components/"] + ``` + + A trailing slash marks a directory prefix. Declaring a path whose subject is a Python module + is a review failure. +- **Group tests into classes**, one `Test` class per unit, so one area can be run on its + own: `pytest tests/test_models.py::TestConceptModel`. +- **One factory per model.** Each model has exactly one `factory_boy` `DjangoModelFactory` in + `tests/factories.py`, using `factory.Sequence` for unique fields and `factory.SubFactory` for + relations. Variants override fields at the call site. They are never factory subclasses. +- **Fixtures wrap factories, and shared setup lives in `conftest.py`.** `def concept(): return + ConceptFactory()`. A one-off variation calls the factory inline. Test modules hold assertions, + not construction. +- **Use the pytest-django toolchain.** Database access through `db`, `transactional_db` or + `@pytest.mark.django_db`. Requests through `client`, `admin_client` or `rf`. No + `unittest.TestCase`. The tools come pinned in the `mvp-shared[test]` bundle. +- **A run writes files only inside its own directory, and a factory attaches none unless asked.** + `MEDIA_ROOT`, and `STATIC_ROOT` where anything writes to it, point at a directory the runner + creates and removes for the run (`tmp_path_factory`). That has to hold under `pytest-xdist`. A + factory that can attach a file leaves the field empty by default, and a test that needs a file + asks for one (`ProjectFactory(with_image=True)`). A downstream project inherits a package's + factories without its test settings, so a factory that writes on every build fills that + project's media directory. + +## 5. Django checks + +| Check | How | +|---|---| +| No N+1 queries on list and detail pages | Render with one record and with several, and assert the same query count under `django_assert_num_queries`. Never pin a count that grows with rows, and never time a request. | +| Migrations are complete | `python manage.py makemigrations --check` is clean after the change. | +| Every model field has `verbose_name` and `help_text` | One parametrised test over every field of every model. Never one test per field, and never asserting the wording. | +| Template output for component changes | Render the template, not only the context. A context key can be right while the template never renders it. | +| Translated strings compare correctly | Compare `str(value)`. A lazy translation proxy can pass or fail `==` for the wrong reason. | + +## 6. Coverage + +- **Project ≥ 90%, patch ≥ 85%,** with a 1% tolerance, as set in `codecov.yml`. They are floors, + not a ratchet towards 100%. +- Only Python is measured. Templates are not, so markup left untested under section 1 does not + lower the figure. Do not enable template coverage. +- A test written only to raise coverage is still bound by section 1. + +## Project additions + + + +--- + +**Version**: 1.0.0 diff --git a/tests/portal/pyproject.toml b/tests/portal/pyproject.toml index 87ac424..0bf0002 100644 --- a/tests/portal/pyproject.toml +++ b/tests/portal/pyproject.toml @@ -10,7 +10,7 @@ dependencies = ["fairdm"] dev = ["mvp-shared[dev,test]"] [tool.uv.sources] -fairdm = { git = "https://github.com/FAIR-DM/fairdm", rev = "fc3e29a292393c5c65b925b794409e817ec27015" } +fairdm = { git = "https://github.com/FAIR-DM/fairdm", rev = "1c2e0819647164c917d10316025630239ce346f0" } mvp-shared = { git = "https://github.com/django-mvp/shared.git", tag = "v0.6.0" } [tool.ruff] diff --git a/tests/portal/uv.lock b/tests/portal/uv.lock index 6eadb39..3dddb6e 100644 --- a/tests/portal/uv.lock +++ b/tests/portal/uv.lock @@ -1995,7 +1995,7 @@ dev = [ ] [package.metadata] -requires-dist = [{ name = "fairdm", git = "https://github.com/FAIR-DM/fairdm?rev=fc3e29a292393c5c65b925b794409e817ec27015" }] +requires-dist = [{ name = "fairdm", git = "https://github.com/FAIR-DM/fairdm?rev=1c2e0819647164c917d10316025630239ce346f0" }] [package.metadata.requires-dev] dev = [{ name = "mvp-shared", extras = ["dev", "test"], git = "https://github.com/django-mvp/shared.git?tag=v0.6.0" }] @@ -2033,7 +2033,7 @@ wheels = [ [[package]] name = "fairdm" version = "0.1.0" -source = { git = "https://github.com/FAIR-DM/fairdm?rev=fc3e29a292393c5c65b925b794409e817ec27015#fc3e29a292393c5c65b925b794409e817ec27015" } +source = { git = "https://github.com/FAIR-DM/fairdm?rev=1c2e0819647164c917d10316025630239ce346f0#1c2e0819647164c917d10316025630239ce346f0" } dependencies = [ { name = "celery" }, { name = "daisy-cotton-ext" },
