test(tools): pin user-facing CLI text against golden transcripts - #3341
Closes nine rows of the gap audit #3214 (C15-01, C15-02, C15-03, C15-07, C15-09, C15-10, C15-11, C15-12, C15-13) plus one row that no longer applies: the user-facing CLI text is now pinned end to end against golden transcripts served by the real binaries (ADR-3402).
test_vmaf_cli_text_golden.sh (new, suite fast): vmaf --help diffed against the full 189-line transcript; the vmafx alias asserted byte-identical (modulo argv[0]) and pinned on its own VMAFX ... (auto-backend, precision=max) version line; --version pinned as a format (semver + optional -<N>-g<sha>); five error transcripts pinned with exit codes — --width (unparsable / negative / zero), --precision, --model — each as its reason line plus the full usage dump (every usage() refusal ends with print_usage, so one golden covers both halves); the two raw-yuv geometry refusals (exit 2, exact declared-vs-actual sizes).
test_vmaf_roi_usage.sh / test_vmaf_vpl_usage.sh (new, suite fast): the hand-written vmaf_roi usage block, and the vmaf_vpl usage block with its Error: --ref and --dis are required refusal — split into two tests on review so the roi golden is a real PASS in every build; the vpl test skips (exit 77) outside Linux SYCL builds and is verified by the Ubuntu SYCL lanes (the only places vmaf_vpl is built).
test_vmaf_per_shot.sh (extended): per_shot_print_usage() pinned on both paths — --help (stdout, exit 0) and no-args (stderr, exit 1) — where previously only the exit code was checked. This one pin sits in the slow suite, where the smoke it extends already runs; the other pins are in fast.
Goldens under core/tools/test/golden/ (4 files). argv[0] is normalised (Usage: <app> ...) because it varies across platforms and invocation paths; \r is stripped on both sides because the Windows CRT writes CRLF through a pipe. The vmaf_vpl golden embeds the current VMAF_DEFAULT_MODEL_VERSION on purpose — a default-model bump must regenerate it consciously.
Text changes are regen-by-design: an intended wording change regenerates its golden in the same pull request, so the review diff shows the exact user-visible change.
REUSE.toml: the golden transcripts are diff targets and cannot carry inline SPDX headers, so they are annotated as an override block (Copyright 2026 luoye-cpu, EUPL-1.2) per ADR-3401.
Row C15-08 no longer applies on master: core/tools/test/test_vmaf_read_error_exit.sh already greps the user-facing stderr strings — line 81 grep -q "problem while reading pictures" and line 94 grep -q "ended before" (checked against master @ 1907cd6e0, per the issue's re-check instruction). Please tick it with this PR or the reason.
Rows C15-04/05/06 stay open: JSON Schema, XSD and CSV-column validation would introduce dependencies the repo does not carry (jsonschema has zero references today) — that is a dependency decision, not a test-writing one.
Rows C15-17..25 stay open: they are Go-side; this contribution deliberately does not assume a Go toolchain beyond the repo's own CI.
Type
test — new/extended test coverage only (three shell tests + four golden transcripts + ADR; no product behaviour, no score change)
Every commit is signed off (git commit -s). See DCO sign-off.
make format && make lint is green locally — shell-only change: shellcheck -s sh clean on all three touched scripts; no Python touched.
Unit tests pass — locally verified against a MinGW/Windows build of tools/vmaf, tools/vmafx, tools/vmaf_roi, tools/vmaf-perShot: test_vmaf_cli_text_golden.sh PASS (all 9 cases), test_vmaf_per_shot.sh full suite PASS, test_vmaf_roi_vpl_usage.sh roi half PASS with the vpl half skipping 77 as designed (the vpl golden is source-derived and is executed by the Ubuntu SYCL lanes).
If I touched any SIMD/GPU code path, I ran /cross-backend-diff and the worst ULP is ≤ 2. — not applicable: test/shell only.
If I touched a feature extractor with SIMD/GPU twins, I either updated every twin or listed the gap under "Known follow-ups" below. — not applicable.
If I added a new .c / .cpp / .cu / .h / .hpp, it has the appropriate license header (see CONTRIBUTING.md). — new files are .sh/.txt/.md with the SPDX headers or the REUSE annotation.
If this is a breaking change, the commit message uses ! or BREAKING CHANGE: and the migration path is documented below. — not a breaking change: additive tests.
If this PR adds an ADR, the ADR row lives in docs/adr/_index_fragments/<NNNN-slug>.md and nothing else is touched for the index. — ADR-3402 added with its fragment only.
docs/state.md updated in this PR with a row in the appropriate section, OR the opt-out line — no state delta: test-only change; no product behaviour or score changes.
I did not modify any assertAlmostEqual(...) score in the Netflix golden Python tests, except by porting Netflix's own updated assertion verbatim from upstream.
If I believe a golden value must change, I have explained why below AND pinged @lusoris for a CODEOWNERS exception. — not applicable: no golden score touched; the new CLI text goldens are test fixtures, not score assertions.
Decision matrix — no alternatives to weigh beyond the three recorded (and rejected) ones in ADR-3402: codegen-idempotency-only, heredoc goldens, argv[0]-pinning.
AGENTS.md invariant note — no rebase-sensitive invariants: self-contained new test files plus one meson.build registration carry no ordering a rebase could silently break.
Reproducer / smoke-test command — meson test -C build test_vmaf_cli_text_golden test_vmaf_roi_vpl_usage test_vmaf_per_shot (from the build root; the scripts also run standalone via sh core/tools/test/<name>.sh with the build tree as cwd).
CHANGELOG fragment — no changelog entry needed: test-only, no user-discoverable surface change.
Rebase note — rebase impact: the four goldens under core/tools/test/golden/ will conflict on any help-text change; resolution is always "regenerate the golden from the post-rebase binary", never a hand-merge. The test_vmaf_per_shot.sh hunk sits right after its # 1. --help returns 0. block; a conflict there keeps both neighbouring checks.
Summary by Sourcery
Guard user-facing CLI text against unintended changes by adding portable golden transcript coverage for the VMAF tools and their sidecars.
Enhancements:
Pin user-facing CLI help, version formats, option errors, geometry errors, and sidecar usage text against golden transcripts from the built binaries.
Normalize platform-dependent argv[0] and line endings so the transcript checks remain portable across invocation paths and operating systems.
Documentation:
Document the end-to-end CLI golden transcript policy and record ADR-3402 in the ADR index.
Tests:
Add fast-suite transcript tests for vmaf/vmafx, vmaf_roi, and vmaf_vpl, including expected exit codes and refusal output.
Extend per-shot coverage to verify identical usage text for both --help and no-argument paths.
Chores:
Add REUSE metadata for the golden transcript fixtures.
Summary by CodeRabbit
Tests
Added checks for command-line help and version output, option errors, and invalid video geometry across the main and companion tools.
Added usage-output checks for the ROI and VPL tools, including expected output streams and exit statuses.
Documentation
Added an architecture decision record describing which command-line text is covered by transcript checks and how updates are handled.
The gap audit (issue VMAFx#3214, rows C15-01..C15-13) found that the text a
user actually reads — the vmaf/vmafx help, --version output, the sidecar
usage blocks, and the option-error and geometry-error transcripts —
could change without any test noticing. The codegen unit tests shape
synthetic fixtures, dnn/test_cli.sh greps three flag strings, and the
error-path tests assert exit codes and single substrings; none guards
the bytes the built binary serves (ADR-3402).
- test_vmaf_cli_text_golden.sh: the vmaf --help transcript, the
--version format on both binaries, the vmafx alias behaviour
(byte-identical help modulo argv[0]; its own VMAFX precision=max
version line), the --width/--precision/--model error transcripts, and
the raw-yuv geometry refusals (exit 2, exact sizes in the message).
- test_vmaf_roi_vpl_usage.sh: the hand-written vmaf_roi and vmaf_vpl
usage blocks; the vpl half skips (exit 77) outside Linux SYCL builds
and is verified by the Ubuntu SYCL lanes.
- test_vmaf_per_shot.sh: pin per_shot_print_usage() on both its --help
(stdout, exit 0) and no-args (stderr, exit 1) paths.
Goldens live under core/tools/test/golden/ with argv[0] normalised and
\r stripped on both sides (Windows CRT writes CRLF through a pipe); the
vpl golden embeds the current VMAF_DEFAULT_MODEL_VERSION value on
purpose — a default-model bump regenerates it. A text change is made by
consciously regenerating its golden in the same pull request, so the
review diff shows the exact user-visible change.
## Deliverables (ADR-0108)
- [ ] **Research digest**: no digest needed: the gap is the VMAFx#3214 audit itself; the transcript pins execute its prescription.
- [ ] **Decision matrix**: no alternatives to weigh beyond ADR-3402's recorded ones (codegen idempotency only, heredoc goldens, argv[0]-pinning) — all rejected there with reasons.
- [ ] **AGENTS.md invariant note**: no rebase-sensitive invariants: self-contained new test files plus one meson.build registration carry no ordering a rebase could silently break.
- [x] **Reproducer / smoke-test command** — `meson test -C build test_vmaf_cli_text_golden test_vmaf_roi_vpl_usage test_vmaf_per_shot` (the golden halves verified against the MinGW build on Windows 11; the vpl half exercises on the Ubuntu SYCL lanes).
- [ ] **CHANGELOG fragment**: no changelog entry needed: test-only, no user-discoverable surface change.
ClosesVMAFx#3214 rows C15-01, C15-02, C15-03, C15-07, C15-09, C15-10,
C15-11, C15-12 and C15-13. C15-08 no longer applies on master:
test_vmaf_read_error_exit.sh already greps the user-facing stderr
strings ("problem while reading pictures", "ended before"). C15-04/05/06
stay open pending a validation-dependency decision (JSON Schema, XSD and
CSV-column validation would introduce dependencies the repo does not
carry), and the C15-17..25 rows need a Go toolchain this contribution
does not assume.

Walkthrough
The pull request adds golden transcripts for VMAF command-line output and tests that compare tool output against them. It registers fast-suite checks for core, ROI, and VPL tools, extends per-shot usage checks, and documents the transcript policy in ADR-3402.
Changes: CLI transcript golden tests
Layer / File(s)
Summary
Transcript reference and policy REUSE.toml, core/tools/test/golden/vmaf_help.txt, docs/adr/3402-cli-text-golden-pins.md, docs/adr/_index_fragments/3402-cli-text-golden-pins.md
Adds the VMAF help transcript and a REUSE annotation for CLI golden text. ADR-3402 records the transcript coverage, normalization, and regeneration policy.
VMAF and VMAFx transcript checks core/tools/test/test_vmaf_cli_text_golden.sh, core/tools/test/meson.build
Checks help and version output, option errors, and raw-YUV geometry refusals for vmaf and vmafx. Registers the test in the fast suite.
Adds golden usage transcripts and checks for per-shot, ROI, and VPL tools. Registers the ROI and VPL checks in the fast suite; the VPL test skips when its binary is not executable.
Issue 3214 — The added golden tests cover the issue’s stated transcript objectives for VMAF and VMAFx help, version, option-error, and geometry output, plus usage text for the ROI, VPL, and per-shot tools.
Merge Risk: Low · previous review e0269
Correct the new copyright notices and golden-file licensing metadata; copied help text currently has incorrect attribution and terms.
Security architecture risk: Minimal · up to e0269
The change makes existing CLI output expectations explicit and adds regression checks. No material security risk was identified: production parsing, privileges, dependencies, and deployment behavior remain unchanged.
Retained concerns
No architecture-level concerns identified.

Pull Request Overview
👀 Worth a closer look
The ROI usage test is skipped wholesale when VPL is unavailable, so an independently runnable CLI contract is not enforced in common builds. Split the checks or adjust skip handling to preserve ROI coverage.
Test suggestions
vmaf --help matches the complete golden transcript and uses the expected stdout/stderr behavior
vmafx help matches vmaf help after argv[0] normalization
vmaf and vmafx version outputs match their required formats
Width, precision, and model option errors match expected exit codes and transcripts
The reason will be displayed to describe this comment to others. Learn more.
🟡 MEDIUM RISK
Split the ROI and VPL checks into separate Meson tests, or otherwise avoid returning 77 for the whole script, so the ROI golden check remains enforced when VPL is not built.
TIP React 👍 if this review is right, or reply with what's wrong and how it could be better to help improve the reviewer.

On review: folding both sidecars into one script made the roi golden a
passenger of the vpl skip — a non-SYCL build reported the whole test as
skipped (exit 77) even though the roi transcript had been checked, so
the roi contract had no independent pass/fail signal in the common
builds. Two registrations change that: test_vmaf_roi_usage runs and
passes everywhere, test_vmaf_vpl_usage keeps the skip for the SYCL-only
binary and is verified by the Ubuntu SYCL lanes.
The ADR now also states the suite truth: the per-shot pin lives in the
slow suite next to the smoke it extends, not in fast.
## Deliverables (ADR-0108)
- [ ] **Research digest**: no digest needed: review-driven split; no behaviour besides the registration boundary changed.
- [ ] **Decision matrix**: no alternatives to weigh: splitting is the reviewer-suggested option that preserves the fast-suite contract without moving the pre-existing slow smoke.
- [ ] **AGENTS.md invariant note**: no rebase-sensitive invariants: one script replaced by two, one registration block rewritten in place.
- [x] **Reproducer / smoke-test command** — `meson test -C build test_vmaf_roi_usage test_vmaf_vpl_usage` (locally: roi PASS, vpl skips 77 on the MinGW build; the meson introspection lists both registrations).
- [ ] **CHANGELOG fragment**: no changelog entry needed: test-only, unmerged PR follow-up.

Eight checks are red on this head (e02690297). They come from three causes, all in this PR, so I am requesting changes.
1. The version regex rejects a prerelease tag.test_vmaf_cli_text_golden fails on macOS Clang+Metal, Linux Intel LLVM and Sanitizers ASan+UBSan with the same output:
v1.0.0-rc.3-695-ge9e2466e8
test_vmaf_cli_text_golden: vmaf --version does not match the version format
Those lanes fetch tags, so git describe starts from v1.0.0-rc.3, and VER_RE (line 79) has no room for a semver prerelease. The VMAFX v... check at line 99 has the same gap. A pattern that accepts the prerelease and keeps the describe suffix:
Checked with grep -E: it accepts v1.0.0-rc.3-695-ge9e2466e8, v1.0.0-rc.3, v0.1.0 and v0.1.0-12-gabc1234, and still rejects 1.0.0, v1.0 and v1.0.0 extra. The current pattern accepts only the last two of the four valid strings. To reproduce, build from a clone that has the tags, then run meson test -C build test_vmaf_cli_text_golden.
2. ADR-3402 is taken twice. ADR Collision Guard: your #3329 adds docs/adr/3402-vulkan-integer-compute-path.md too. Renumber the ADR in one of the two PRs to the next number that neither master nor an open PR uses (the guard checks both), together with its _index_fragments file and every reference to it.
3. The Rebase note box is ticked without a fragment. Deliverables Checklist: Checkbox ticked but no docs/rebase-notes.d/<slug>.md fragment is in this PR (ADR-2197). Your note text is useful, so move it into docs/rebase-notes.d/<slug>.md and keep the box ticked.
On the open CodeRabbit thread at test_vmaf_roi_usage.sh:2: keep Copyright 2026 luoye-cpu. A file an outside contributor writes carries the author's own name (CONTRIBUTING.md, License headers; ADR-3401). The bot is reading older guidance in several AGENTS.md files that still say otherwise. That is our defect, and I will fix it in a separate PR. I replied on the thread.
The open Codacy thread at test_vmaf_vpl_usage.sh:34 looks covered by your split into test_vmaf_roi_usage.sh and test_vmaf_vpl_usage.sh. Please reply there and resolve it.
The diff touches only test scripts, goldens, meson.build, REUSE.toml and the ADR, so I am approving the 16 queued runs for this head now. Each new push needs a new approval, and I give it after reading the diff.

Blocking: one more item for review 5817216887. The files you wrote here need a docs/credits.yaml entry, so the credits page names your work.
make docs-fragments-check passes at e026902 without it, for two reasons that do not replace the entry:
the netflix-vmaf entry lists core/, which covers every path under it;
the new REUSE.toml annotation names you as a holder under EUPL-1.2, and the check treats such holders as project contributors (scripts/docs/credits_checks.py:103).

Summary
Closes nine rows of the gap audit #3214 (C15-01, C15-02, C15-03, C15-07, C15-09, C15-10, C15-11, C15-12, C15-13) plus one row that no longer applies: the user-facing CLI text is now pinned end to end against golden transcripts served by the real binaries (ADR-3402).
test_vmaf_cli_text_golden.sh(new, suitefast):vmaf --helpdiffed against the full 189-line transcript; thevmafxalias asserted byte-identical (modulo argv[0]) and pinned on its ownVMAFX ... (auto-backend, precision=max)version line;--versionpinned as a format (semver + optional-<N>-g<sha>); five error transcripts pinned with exit codes —--width(unparsable / negative / zero),--precision,--model— each as its reason line plus the full usage dump (everyusage()refusal ends withprint_usage, so one golden covers both halves); the two raw-yuv geometry refusals (exit 2, exact declared-vs-actual sizes).test_vmaf_roi_usage.sh/test_vmaf_vpl_usage.sh(new, suitefast): the hand-writtenvmaf_roiusage block, and thevmaf_vplusage block with itsError: --ref and --dis are requiredrefusal — split into two tests on review so the roi golden is a real PASS in every build; the vpl test skips (exit 77) outside Linux SYCL builds and is verified by the Ubuntu SYCL lanes (the only placesvmaf_vplis built).test_vmaf_per_shot.sh(extended):per_shot_print_usage()pinned on both paths —--help(stdout, exit 0) and no-args (stderr, exit 1) — where previously only the exit code was checked. This one pin sits in theslowsuite, where the smoke it extends already runs; the other pins are infast.core/tools/test/golden/(4 files). argv[0] is normalised (Usage: <app> ...) because it varies across platforms and invocation paths;\ris stripped on both sides because the Windows CRT writes CRLF through a pipe.

core/tools/test/test_vmaf_read_error_exit.shalready greps the user-facing stderr strings — line 81grep -q "problem while reading pictures"and line 94grep -q "ended before"(checked againstmaster@1907cd6e0, per the issue's re-check instruction). Please tick it with this PR or the reason.Rows C15-04/05/06 stay open: JSON Schema, XSD and CSV-column validation would introduce dependencies the repo does not carry (
jsonschemahas zero references today) — that is a dependency decision, not a test-writing one.Rows C15-17..25 stay open: they are Go-side; this contribution deliberately does not assume a Go toolchain beyond the repo's own CI.
