[test-parallel] test: parallelize safe Go test (daily batch) - #55047
Conversation
|
👋 Thanks for opening this PR! However, this appears to be a work-in-progress pre-created by an automated GitHub Actions workflow for the Daily Go Test Parallelizer rather than a traditional external contribution. Since this is an internal agentic workflow PR created by the core team automation, it falls outside the scope of the contributing guidelines for external contributors. The guidelines explicitly state:
If you are a core team member working on this internal workflow, please disregard this evaluation - the PR will be assessed once the agent completes its work and actual changes are present. If you are an external contributor, please create a detailed agentic plan in an issue instead of a direct PR.

Analyzed 25 test files in pkg/cli/ (compile_guard_policy_test.go through compile_watch_environment_test.go) for safe t.Parallel() additions. Only one test was demonstrably safe to parallelize; the rest use process-global state (os.Chdir via setupIntegrationTest, os.Stdout/os.Stderr redirection, shared package-level vars) that would race under -race if parallelized. TestCompileUpdateDiscussionFieldEnforcement uses only t.TempDir() and local variables, with no shared/global state, making it safe. Verified with 'go test -race' targeting the modified test.
…atch) Analyzed 25 test files (compile_wif_anthropic_integration_test.go through docker_build_integration_test.go) for safe t.Parallel() additions. Safe additions made to: - copilot_setup_runs_on_test.go: TestValidateCopilotSetupStepsRunsOn (pure function, no shared state) - daily_regression_audit_workflow_contract_test.go: TestDailyRegressionAuditAllowsPythonJSONParsing (read-only file checks) - deps_test.go: 8 top-level tests + table-driven subtests (pure helpers, isolated temp files) - docker_args_validation_test.go: 6 top-level tests + table-driven subtests (pure validation functions, isolated temp dirs) - docker_build_integration_test.go: TestIsTransientDockerBuildFailure, TestDockerfile_Exists, TestMakefile_DockerTargets (read-only file/pure checks; Docker build/run tests left unparallelized due to shared image tag and external Docker daemon dependency) Skipped as unsafe: files using os.Chdir, t.Setenv, package-level global reassignment, or unverified shared setup helpers (compile_wif_*_integration_test.go, completions_integration_test.go, completions_test.go, context_cancellation_test.go, copilot_agents_test.go, copilot_billing_check_test.go, copilot_setup_test.go, dependency_graph_test.go, deploy_command_test.go, deploy_org_test.go, devcontainer_test.go). Verified with 'go test -race' targeting all modified tests plus a full 'go test ./pkg/cli/...' run (one pre-existing unrelated network-dependent test failure confirmed present on the pre-change baseline too).

Reviewed as tests_only → audit mode. All changes are t.Parallel() additions to top-level tests and their subtests. No shared mutable state, no ordering dependencies, and t.TempDir() is correctly used where temp directories are needed. LGTM.

Skills-Based Review 🧠
Applied /tdd — changes look safe and well-reasoned; one documentation inconsistency noted.
📋 Key Themes & Highlights
Positive Highlights
- ✅ All added
t.Parallel()calls are on stateless tests using onlyt.TempDir()or local variables - ✅ Subtests consistently get
t.Parallel()alongside their parent, following the correct Go pattern - ✅ The PR body clearly documents the reasoning for files intentionally left unchanged
One Concern
The PR body says "Result: 1 safe change" and only describes compile_update_discussion_test.go, but the diff modifies 6 files. Future readers of the PR history will have an inaccurate summary of what changed.

### Review notes
I checked the newly added t.Parallel() calls against the surrounding test code and the changed files list. The affected tests only read repository files, use per-test temp dirs, or operate on local data, and I did not find newly introduced shared-global mutations, stdout/stderr redirection, cwd changes, or environment writes in the changed sections that would make these specific parallelizations unsafe.
I also checked for duplicate prior review comments and found none to carry forward.
