…ipping The DB-backed suites answered two very different errors with the same t.Skipf: a Postgres testcontainer that would not start, and a set of migrations that would not apply. The first is an environment fact and a legitimate skip. The second is the failure of the thing under test, reported as green. Breaking any SQL file under internal/database/postgres/migrations made the whole integration suite report skipped, with nothing distinguishing "no Docker on this runner" from "the schema is broken". Split the two conditions. testhelpers.RequirePostgresContainer probes the Docker provider directly via testcontainers SkipIfProviderIsNotHealthy, which is the only thing allowed to skip, and requires the container past that probe. Migration errors become require.NoError. false_green_skip_guard_test.go keeps the class closed for tests not yet written: it parses every _test.go in the repo and fails on any if statement that answers an error from SetupPostgresContainer, RunMigrations, MigrateToVersion or RollbackMigrations with a skip. It is parse-only, so it needs no build tag and still sees the files behind //go:build integration. A tripwire fails the guard if it ever finds zero guarded calls, so its own detection cannot break silently. Verified in both directions against a real Docker daemon: with a deliberately invalid migration the suite now FAILs (exit 1) where it previously SKIPped (exit 0), and inside a container with no Docker socket it still SKIPs rather than failing. Closes #1597
… on a total blackout Adversarial review of the previous commit found three real gaps. The anti-vacuity tripwire fired only when the guard found zero guarded calls anywhere. Measured on this tree that total is 188, so it was unreachable from any partial regression: excluding one directory from the walk, or breaking three of the four names, left the tripwire green while the findings for those names silently went to zero. The floor is now per name, which is what the comment always claimed to cover. The walk only parsed _test.go, but this fix moved the skip decision into testhelpers/postgres.go, a non-test file. A future helper that skipped on a container error would have been written in exactly the place the guard could not see. It now also parses the non-test files of the testhelpers and testutil packages. internal/database/coverage_extra_test.go skipped on buildPoolConfig and pgxpool.NewWithConfig errors. Neither does any I/O -- the first parses and validates a DSN, the second builds a lazy pool -- so a failure there is a code defect, not an absent database, and this file carries no //go:build integration tag, so it runs on every default go test. Same defect class as #1597, wider blast radius. Also corrects the RequirePostgresContainer doc, which claimed an exhausted host would fail: SkipIfProviderIsNotHealthy skips on any unhealthy daemon, so the probe owns the whole environment side of the line. Refs #1597
… guard's reach Adversarial review of the previous two commits found four things worth fixing. SetupPostgresContainer terminated the container when NewConnection failed but not when Host or MappedPort did, so those two paths returned an error with the container still running and nothing left holding a handle to call Cleanup on. The reviewer hit exactly that path: MappedPort returned `port "5432/tcp" not found` under container churn, and the container leaked. This matters more after this PR than before it, because the paths that used to end in a skip now end in a failure, so a bad run accumulates live containers rather than skipped tests. All three post-Run error paths now go through one terminate helper. That helper does not forward its caller's context. The error it cleans up after is very often the context expiring in the first place, and Terminate on a dead context returns immediately without stopping anything, so forwarding would have left exactly the leak the helper exists to prevent. It derives a detached context instead. TestTerminateAfterErrorSurvivesDeadContext pins this against a canceled parent and an expired deadline, and fails by assertion on both if the detach is removed while its live-parent case keeps passing. The guard's header claimed it "closes the class of defect behind #1597 for tests not yet written". It does not, and the claim is the kind that stops the next reader from looking. Probing inspectFile directly found four shapes it does not detect: a skip behind a helper, a switch case rather than an if, an assignment in the parent with the check inside a t.Run closure, and a wrapper that returns the guarded call's error. Two are realistic, and "extract a setup helper" is the natural next refactor over this code. The header now says tripwire rather than proof, and rather than listing the shapes in prose where they would drift, TestFalseGreenSkipGuardKnownBypasses executes all four. Each case also asserts the guarded call stays countable, so a bypass hides a finding but cannot also silence the per-name floor. If the guard is later widened to catch one, that test fails and says to move the case into the detects test. The walk pruned any directory named frontend at any depth rather than the TypeScript tree at the repo root. terraform/modules/frontend was being pruned by that; it holds no Go files, so nothing was lost, but a Go package named frontend would have been dropped silently. The prune is now anchored to the root. files++ ran before parser.ParseFile, so the reassuring total in the log counted files that may never have been inspected, which is the same "found nothing and looked at nothing are the same color" reasoning the per-name floor exists for. It now counts only parsed files: 386, which is exactly the 382 test files plus the 4 non-test files in testhelpers and testutil, so no file is failing to parse today. Also renames analytics' skipIfNoDocker to skipIfDBTestsOptedOut. It never probed Docker; it reads SKIP_DB_TESTS. The old name is what makes a reader of #1597 believe a suite reporting nothing was accounted for. The opt-out itself stays: it is a caller's decision rather than an error answered with a skip, and nothing in the tree sets the variable outside tests. Refs #1597

…own file false_green_skip_guard_test.go had grown to 526 lines against the project's 500-line limit. The file is new in this PR, so the violation is this change's own rather than pre-existing debt, and it is in scope to fix here. TestFalseGreenSkipGuardDetects and TestFalseGreenSkipGuardKnownBypasses move verbatim into false_green_skip_guard_cases_test.go in the same package. The detector itself, the repo-wide walk in TestNoSkipOnDatabaseSetupFailure, and the guardedCalls and skipFuncs tables stay where they were. The split falls on the natural seam: what the detector is stays in one file, the synthetic sources proving what it does and does not catch move to the other. The two files are now 329 and 205 lines. This is a pure move. 196 lines were transplanted byte for byte, with no logic, signature or name changes; the only authored lines are the new file's package clause and its four-import block. Neither file carries a build tag, before or after, which is what lets the guard keep seeing the files behind //go:build integration that a default `go test` never compiles. The package's test set is identical before and after: the same 5 top-level tests and 7 subtests, all passing, none skipped, both with and without -tags=integration. Complexity attribution is unchanged as well, with TestNoSkipOnDatabaseSetupFailure still at 14 and TestFalseGreenSkipGuardDetects still at 9, and both the CI and pre-commit gocyclo gates exclude _test.go.

Problem
The DB-backed integration suites answered two very different errors with the same
t.Skipf:"The container would not start" is an environment fact and a legitimate skip. "The migrations would not apply" is the failure of the thing under test, reported as green. Break any SQL file under
internal/database/postgres/migrations/and the entire Postgres integration suite reported skipped, with nothing distinguishing "no Docker on this runner" from "the schema is broken".Change
Split the two conditions.
testhelpers.RequirePostgresContainerprobes the Docker provider directly (testcontainers' ownSkipIfProviderIsNotHealthy); that probe is the only thing allowed to skip. Past it, a container that still refuses to come up is a real failure, and migration errors becomerequire.NoError.A guard narrows the class for tests not yet written.
false_green_skip_guard_test.goparses every_test.goin the repo and fails on anyifstatement that answers an error fromSetupPostgresContainer,RunMigrations,MigrateToVersionorRollbackMigrationswith a skip. It is parse-only, so it costs milliseconds, needs no build tag, and still sees the files behind//go:build integrationthat a defaultgo testnever compiles.It does not close the class, and the PR no longer claims it does.
TestFalseGreenSkipGuardKnownBypassesexecutes four shapes the guard cannot see and records them as tests, so the guard's reach is written down and checked rather than assumed. A bypass hides a finding but cannot also silence the per-name floor below.The guard has a tripwire of its own, because "found nothing" and "looked at nothing" are the same color on a terminal. It fails if any one of the four guarded names goes unseen across the whole repo. A total-only floor would have been unreachable: the total is 188 (41 + 11 + 72 + 64), so excluding a single directory from the walk, or breaking three of the four names, would leave it green while those names' findings silently went to zero.
The guard also parses the non-test files of the
testhelpersandtestutilpackages, not just_test.go. This fix moved the skip decision intotesthelpers/postgres.go, so that is now precisely where the next helper that skips would be written, and a_test.go-only walk could not see it.Leaked containers are terminated on the path this PR makes loud. Converting a skip into a failure is only safe if the failure path still cleans up; otherwise making the suite honest also makes it leak.
One related site outside the issue's wording
internal/database/coverage_extra_test.goskipped onbuildPoolConfigandpgxpool.NewWithConfigerrors. Neither does any I/O (the first parses and validates a DSN, the second builds a lazy pool withMinConnections: 0), so a failure there is a code defect rather than an absent database. This file carries no//go:build integrationtag, so unlike everything else in this PR it runs on every defaultgo test. Same defect class as #1597 with a wider blast radius, so it is converted here.What the issue got wrong
#1597 lists
internal/secrets/*_resolver_coverage_test.goalongsideinternal/analyticsas holding 40+ sibling skip sites. That half is inaccurate.internal/secrets/contains no postgres or migration skips; its ~24 skips answerNewAWSResolver/NewGCPResolverconstruction errors, a different function family and arguably a genuine environment fact. Those files are correctly untouched here. Noted so a reviewer checking the issue's file list against this diff does not see a gap that is not real. The same correction is posted on the issue.Consequence worth knowing before merging
This PR converts transient container-lifecycle failures into hard CI failures, not just genuine ones. Under container churn, testcontainers can log
Container is readyand then failMappedPortwithfailed to get container port: port "5432/tcp" not found, observed at roughly 1 in 10 container starts during review, and confirmed a flake rather than a regression (the same test passes 3/3 alone and onmain).That is correct by this PR's own design: at that point you cannot distinguish "host exhausted" from "something is genuinely broken", and choosing red is the fail-loud answer. But CI runs
-raceacross six modules, which is exactly the churn that produces it, so expect intermittent reds.No retry was added. A retry layer is its own bug surface and the flake rate should be measured before one is built. Tracked in LeanerCloud/cloud-commitments-platform#202, which also carries a same-family false green at
internal/config/store_postgres_db_test.go:576-578that is out of scope here.Verification
Both directions, against a real Docker daemon. Getting only one right is the trap: fail on everything and every machine without a local Postgres breaks; skip on everything and the bug is still there.
(a) A real migration failure now FAILs. Invalid SQL appended to

(b) A genuinely Docker-less environment still SKIPs.
DOCKER_HOSTcannot express this on a machine that has Docker: testcontainers'extractDockerHosttreats a failing host check as a reason to try the next strategy, so it falls through to the real/var/run/docker.sock. The faithful simulation is a container with no Docker socket, which is what a runner without Docker actually looks like:The guard fails pre-fix. Copied onto
