Summary of Changes

Hello @danielschlegel, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request undertakes a substantial internal refactoring effort focused on modernizing the project's testing practices. By transitioning from a third-party testing framework and mocking library to standard Go testing with testify/mock, the codebase benefits from reduced external dependencies, improved maintainability, and alignment with more widely adopted Go testing idioms. This change impacts a broad range of test files, ensuring a consistent and robust testing methodology across the project.

Highlights

  • Testing Framework Migration: The project's testing infrastructure has been significantly refactored, moving away from the onpar testing framework and hel mocking library. Tests now utilize the standard Go testing package in conjunction with stretchr/testify/mock for mock implementations.
  • Dependency Cleanup: The go.mod and go.sum files have been updated to remove the onpar and hel dependencies, reflecting the migration to a new testing approach. A new indirect dependency, github.com/stretchr/objx, has been added, likely due to testify/mock.
  • Test Code Refactoring: Numerous test files across various packages (cmd/earthly/subcmd, util/llbutil/authprovider, util/proj, variables) have been updated. This includes restructuring test suites from onpar.BeforeEach/o.Spec to t.Run subtests, replacing onpar matchers and assertions with standard Go assertions and testify/mock's assertion capabilities, and manually rewriting hel-generated mocks to testify/mock implementations.
Changelog
  • cmd/earthly/subcmd/cmds_test.go
    • Removed onpar imports and related test context setup.
    • Replaced onpar.TableSpec with standard t.Run subtests and direct t.Errorf assertions for help usage and description checks.

Code Review

This pull request does an excellent job of refactoring the test suites to remove dependencies on onpar and hel, migrating to standard Go testing patterns with testify/mock. The changes significantly improve the readability and maintainability of the tests. My review includes a few suggestions to further clean up the codebase by removing now-unnecessary files and to make some assertions more concise by using reflect.DeepEqual, which is consistent with the testing approach outlined in the pull request description.

I've analyzed the mocking situation in your codebase and created a comprehensive solution to simplify it. Here's what I found and what I recommend:

- **Manual mocks**: The code has `helheim_mocks_test.go` files that say "Code generated manually to replace hel mocks"
- **Hel abandoned**: The project has `//go:generate hel` directives but is no longer using the generated mocks
- **Mixed approach**: Some manual mocks with testify/mock, leading to inconsistency

I recommend switching to [**mockery**](https://github.com/vektra/mockery), which is the **industry-standard** mocking tool for Go:

1. **Most Popular**: 7.8k+ GitHub stars, used by Kubernetes, Docker, and thousands of projects
2. **Active Development**: Regular updates and strong community support
   3. **Integrates with testify/mock**: You're already using testify - mockery generates mocks for it
4. **Automatic Generation**: No more manual mock writing
5. **Type Safe**: Expecter pattern with full compile-time type safety
6. **Better IDE Support**: Full autocomplete and refactoring support

1. **`.mockery.yaml`** - Configuration file for automatic mock generation
2. **Updated `Earthfile`** - Replaced hel with mockery in the `+mocks` target
3. **`docs/mocking.md`** - Complete documentation with examples and best practices
4. **`docs/mocking-migration.md`** - Step-by-step migration guide from manual mocks
5. **Updated source files** - Removed hel directives, added mockery comments

Key Benefits

✅ **No more manual mock maintenance**
✅ **Interface changes auto-update mocks**
✅ **Better type safety with expecter pattern**
✅ **Full IDE autocomplete support**
✅ **Industry-standard approach**
✅ **Configuration-driven (`.mockery.yaml`)**

The documentation I created includes:
- Complete usage guide with real examples
- Migration steps from your current approach
- Best practices and common patterns
- Troubleshooting section
- Real-world examples from your codebase
- Remove empty imports_test.go files that only contained comments
- Use reflect.DeepEqual for slice comparisons in scope_test.go for more concise assertions

Addresses review comments from gemini-code-assist in PR #319
This commit fixes all 10 linting errors reported in GitHub Actions:

1. **copyloopvar (3 errors)**: Remove unnecessary range variable captures
   - variables/scope_test.go: Removed 'tt := tt'
   - cmd/earthly/subcmd/cmds_test.go: Removed 'subCmd := subCmd'
   - util/llbutil/authprovider/podman_test.go: Removed 'e := e'
   These are no longer needed in Go 1.22+ as the language now properly
   captures loop variables in closures.

2. **wsl (6 errors)**: Add missing blank lines before if statements
   - variables/scope_test.go: Added blank lines after assignments before if
   - variables/collection_test.go: Added blank lines after assignments before if
   - util/llbutil/authprovider/podman_test.go: Added blank lines after assignments before if
   - util/proj/golang_test.go: Added blank line after assignment before if
   The wsl linter requires blank lines between different statement types
   for better code readability.

3. **godoclint (1 error)**: Fix package documentation format
   - util/llbutil/authprovider/doc.go: Package comment now starts with
     'Package authprovider' as required by godoclint

All tests continue to pass after these formatting fixes.
danielschlegel and others added 8 commits February 4, 2026 17:48
Removes unnecessary blank lines between DeclareVar calls and error
checks to satisfy gofumpt formatter requirements.
The test was looking for 'Error.*path must be located under' but the actual
error message format is 'unable to save to <path>; path must be located under .'
which doesn't start with 'Error'. Updated the pattern to just match
'path must be located under' which works for both error message formats.
