Test Framework Bootstrap
Browser /qa only, never functional/report-only. Read CLAUDE.md/TESTING.md: a documented command skips bootstrap; use it and read 2-3 tests. Otherwise gather evidence, never guess commands:

[ -f .gstack/no-test-bootstrap ] && echo "BOOTSTRAP_DECLINED"ANY test config/script/make target, nonzero TESTFILES or Rust in-source tests means do not bootstrap, even without tests/. Print “Existing tests detected: {evidence}.” AskUserQuestion for the command (below + Other), save it in CLAUDE.md ## Testing, read 2-3 tests for naming/import/assertion/setup conventions, then stop. No second framework beside real tests.
OFFER: Django python manage.py test (pytest with pytest-django); Python pytest; Ruby bundle exec rspec/bin/rails test/rake test; Go go test ./...; Rust cargo test; JVM mvn test/./gradlew test; PHP composer test/./vendor/bin/phpunit; Elixir mix test; Node's test script via its lockfile's manager; Makefile make test.
BOOTSTRAP_DECLINED: announce/skip. Unknown runtime: AskUserQuestion (runtimes, Other runtime/command, or “No tests needed”). Any decline writes .gstack/no-test-bootstrap; explain deletion permits retry. Monorepo: ask which first, or both sequentially.
With NO test evidence, research:

| Runtime | Primary | Alternative |
|---|---|---|
| Rails | minitest + fixtures + capybara | rspec + factory_bot + shoulda-matchers |
| Node | vitest + @testing-library | jest + @testing-library |
| Next.js | vitest + @testing-library/react + playwright | jest + cypress |
| Python | pytest + pytest-cov | unittest |
| Django | pytest + pytest-django | manage.py test |
| Go | stdlib testing + testify | stdlib |
| JVM | JUnit 5 + AssertJ | JUnit 5 |
| Rust | cargo test + mockall | built-in |
| PHP | phpunit + mockery | pest |
| Elixir | ExUnit + ex_machina | built-in |
AskUserQuestion and WAIT: A) primary, B) alternative (rationale/packages/layers), C) skip. Recommend; install only the actual choice.
Install and verify
Record existing files/edits. Install approved packages, minimal config/directories and one project-specific test. If installation fails, diagnose once; if blocked, undo ONLY owned changes, preserve user edits, report/continue without tests. Never blanket-checkout.
First real tests: git log --since=30.days --name-only --format="" | sort | uniq -c | sort -rn | head -10. Prioritize by risk: error handlers > conditional logic > APIs > pure functions. Aim for 3-5 tests (min 1, max 5), meaningful assertions (not toBeDefined()), fixtures/environment variables, never credentials.
Run each test, then the full verified command. Distinguish setup/fixture failure from defects: repair invalid fixtures once; persistent setup failure undoes only owned changes and remains reported. Never silently delete a valid red regression. Keep test/evidence; return defects to /qa's diagnosis/fix gate. Never bless broken behavior or claim green.
Finish
Inspect .github/, .gitlab-ci.yml, .circleci/, bitrise.yml. GitHub Actions (default if none): create/extend .github/workflows/test.yml with push + pull_request, ubuntu-latest, runtime setup and verified command. Preserve existing workflows. Other providers need a reported manual test-step addition.
Update, never overwrite TESTING.md: framework/version, command, unit/integration/smoke/E2E layers, naming/assertion/setup/teardown, and 100% test coverage for safe vibe coding. Add CLAUDE.md ## Testing only if absent: command/directory, TESTING.md link; test new functions, regressions, errors and BOTH branches. Never commit failing existing tests.
Run git status --porcelain. Stage named owned files/hunks; stop for unrelated staged edits. Commit successful bootstrap changes, skip if none: chore: bootstrap test framework ({framework name}).
