fix(tests): reject matcher failures in negative file assertions by kim0 · Pull Request #5175 · cozystack/cozystack

Ahmed Kamal (kim0) · 2026-10-31T21:14:52Z

What this PR does

Negative file assertions must not pass when the matcher fails or an artifact is missing. Share assert_file_lacks_pattern through the existing Bats helper, preserving all call sites while removing the 12 divergent copies. The shared implementation accepts absence only when awk evaluates successfully and explicitly reports no match. It reports read/evaluation failures regardless of their exit status and validates the regex even when the artifact is empty.

Regression tests run the assertion under bash -eu and cover matching and non-matching patterns, empty files, invalid regexes, missing paths, directories, and unreadable files. The tests reproduce false positives against the previous helper implementations, including a matcher that prints a no-match result but exits with an error. The test suite resolves its helper relative to its own directory and also runs outside the repository root.

Validation

Bats 1.14.0: all 471 tests in the regression file and 12 affected consumer suites pass, with no skips.
All 462 tests in the 12 affected consumer suites pass under the dash POSIX compatibility runner.
All nine helper tests pass from both the repository root and /tmp; independent verification also passes all nine with BusyBox awk v1.35.0. The previous helper falsely accepts invalid patterns and unreadable files with that implementation.
bash -n hack/test_helper.bash and git diff --check pass.
An earlier full Bats run executed all 2,491 tests: 2,426 passed and 65 failed. Of these, 56 require Docker and three require envsubst, neither of which is installed in this environment. The remaining six selector failures also reproduce on the unchanged baseline with the older local yq; rerunning both selector suites with the CI-pinned, checksum-verified yq v4.53.3 passes all 110 tests. The full-tree suite has not been rerun for this corrective revision; its focused checks are listed above.

Release note

fix(tests): fail negative file assertions on invalid patterns or unreadable artifacts and share the helper across Bats suites.

Summary by CodeRabbit

Tests
- Consolidated checks for verifying that files do not contain specified patterns.
- Expanded coverage to verify behavior for matching and non-matching patterns, invalid patterns, missing paths, directories, inaccessible files, and pattern-checking errors.
- Checks now succeed only when the target is a regular file and pattern evaluation completes successfully without finding a match.

Walkthrough

The pull request adds assert_file_lacks_pattern to the shared test helper and adds tests for its behavior. It removes local definitions from multiple Bats suites while leaving their calls in place.

Changes: Shared negative pattern assertion

Layer / File(s)	Summary
Shared helper and regression coverage `hack/test_helper.bash`, `hack/test-helper_test.bats`	The shared helper rejects non-regular files, pattern matches, and `awk` errors. Tests cover non-matches, matches, invalid patterns, missing paths, directories, unreadable files, and matcher errors.
Remove local helper definitions `hack/run-kubernetes-block-io_test.bats`, `hack/run-kubernetes-cpu-throttle_test.bats`, `hack/run-kubernetes-kvm-exits_test.bats`, `hack/run-kubernetes-network-counters_test.bats`, `hack/run-kubernetes-node-join_test.bats`, `hack/run-kubernetes-runner-canary_test.bats`, `hack/run-kubernetes-runner-cpu_test.bats`, `hack/run-kubernetes-sandbox-cpu-time_test.bats`, `hack/run-kubernetes-serial-console_test.bats`, `hack/run-kubernetes-talos-diagnostics_test.bats`, `hack/run-kubernetes-thread-cpu_test.bats`, `hack/runner-identity.bats`	Local helper definitions were removed. Calls to the helper remain in the suites.

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Bug fix · Severity of issue fixed: Medium

Merge Risk: Minimal · previous review 21fe9

No actionable issue remains identified; the affected suites load the shared assertion and the change is ready for normal merge checks.

Full details: Linked Issues check

Explanation

Issue #3700 requires negative assertions to fail on matcher errors, unreadable or missing artifacts, and invalid patterns. hack/test_helper.bash rejects non-regular files, validates patterns on empty files, and succeeds only when awk completes and reports no match. hack/test-helper_test.bats covers matching and non-matching patterns, empty files, invalid patterns, missing paths, directories, unreadable files, and a matcher that prints no match but exits with status 1. The PR removes the duplicated helper definitions from the affected consumer suites while retaining their call sites.

Full details: Out of Scope Changes check

Explanation

The changes remain within issue #3700. The shared helper implements the requested fail-closed behavior, the regression tests verify the failure cases, and the consumer-suite edits centralize the helper without changing its call sites. No unrelated change is shown in the reviewed scope.

Full details: Docstring Coverage

Explanation

Docstring coverage is 100.00% which is sufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 1 functions across 2 files.

Review comments at @hack/test_helper.bash:
- Line 34: Update the awk status handling in the assertion so a no-match result
is distinguished from an awk evaluation or read error; accept no match only when
awk exits successfully, and propagate awk failures instead of returning success.

Review comments at @hack/test-helper_test.bats:
- Line 9: Update the helper sourcing in this Bats test to resolve
test_helper.bash relative to BATS_TEST_DIRNAME, passing that path into bash -eu
-c where applicable, so the test works regardless of the current working
directory.

Ahmed Kamal (@kim0) Could you merge main into this branch? The CI runs here date from before several base changes, so the E2E image step can't apply them anymore. Maintainer edits are off on this PR, otherwise I'd have done it myself.

Ahmed Kamal (@kim0) E2E failed during install, and the cause is not this PR. The observability-proxy pods can't pull observability-proxy:v0.0.0: that is the placeholder committed on main, and the PR build replaces it only when the package's values.yaml matches main apart from image lines. Main changed that file after your last merge (#5220, #5277), so the overlay skipped it. Merging main again fixes it. Maintainer edits are off here, so I can't do it myself. The same applies to #5174.

Keep unbuilt package configuration aligned with current-main images so the fork E2E overlay can replace the observability-proxy placeholder. Signed-off-by: Ahmed Kamal <[email protected]> Assisted-by: LLM
