**If test framework detected** (config files or test directories found):
Print "Test framework detected: {name} ({N} existing tests). Skipping bootstrap."
Read 2-3 existing test files to learn conventions (naming, imports, assertion style, setup patterns).
Store conventions as prose context for use in Phase 8e.5 or Step 3.4. **Skip the rest of bootstrap.**

**If BOOTSTRAP_DECLINED** appears: Print "Test bootstrap previously declined — skipping." **Skip the rest of bootstrap.**

**If NO runtime detected** (no config files found): Use AskUserQuestion:
"I couldn't detect your project's language. What runtime are you using?"
Options: A) Node.js/TypeScript B) Ruby/Rails C) Python D) Go E) Rust F) PHP G) Elixir H) This project doesn't need tests.
If user picks H → write \`.gstack/no-test-bootstrap\` and continue without tests.

**If runtime detected but no test framework — bootstrap:**

### B2. Research best practices

Use WebSearch to find current best practices for the detected runtime:
- \`"[runtime] best test framework 2025 2026"\`
- \`"[framework A] vs [framework B] comparison"\`

If WebSearch is unavailable, use this built-in knowledge table:

| Runtime | Primary recommendation | Alternative |
|---------|----------------------|-------------|
| Ruby/Rails | minitest + fixtures + capybara | rspec + factory_bot + shoulda-matchers |
| Node.js | vitest + @testing-library | jest + @testing-library |
| Next.js | vitest + @testing-library/react + playwright | jest + cypress |
| Python | pytest + pytest-cov | unittest |
| Go | stdlib testing + testify | stdlib only |
| Rust | cargo test (built-in) + mockall | — |
| PHP | phpunit + mockery | pest |
| Elixir | ExUnit (built-in) + ex_machina | — |

### B3. Framework selection

Use AskUserQuestion:
"I detected this is a [Runtime/Framework] project with no test framework. I researched current best practices. Here are the options:
A) [Primary] — [rationale]. Includes: [packages]. Supports: unit, integration, smoke, e2e
B) [Alternative] — [rationale]. Includes: [packages]
C) Skip — don't set up testing right now
RECOMMENDATION: Choose A because [reason based on project context]"

If user picks C → write \`.gstack/no-test-bootstrap\`. Tell user: "If you change your mind later, delete \`.gstack/no-test-bootstrap\` and re-run." Continue without tests.

If multiple runtimes detected (monorepo) → ask which runtime to set up first, with option to do both sequentially.

### B4. Install and configure

1. Install the chosen packages (npm/bun/gem/pip/etc.)
2. Create minimal config file
3. Create directory structure (test/, spec/, etc.)
4. Create one example test matching the project's code to verify setup works

If package installation fails → debug once. If still failing → revert with \`git checkout -- package.json package-lock.json\` (or equivalent for the runtime). Warn user and continue without tests.

### B4.5. First real tests

Generate 3-5 real tests for existing code:

1. **Find recently changed files:** \`git log --since=30.days --name-only --format="" | sort | uniq -c | sort -rn | head -10\`
2. **Prioritize by risk:** Error handlers > business logic with conditionals > API endpoints > pure functions
3. **For each file:** Write one test that tests real behavior with meaningful assertions. Never \`expect(x).toBeDefined()\` — test what the code DOES.
4. Run each test. Passes → keep. Fails → fix once. Still fails → delete silently.
5. Generate at least 1 test, cap at 5.

Never import secrets, API keys, or credentials in test files. Use environment variables or test fixtures.

### B5. Verify

\`\`\`bash
# Run the full test suite to confirm everything works
{detected test command}
\`\`\`

If tests fail → debug once. If still failing → revert all bootstrap changes and warn user.

### B5.5. CI/CD pipeline

\`\`\`bash
# Check CI provider
ls -d .github/ 2>/dev/null && echo "CI:github"
ls .gitlab-ci.yml .circleci/ bitrise.yml 2>/dev/null
\`\`\`

If \`.github/\` exists (or no CI detected — default to GitHub Actions):
Create \`.github/workflows/test.yml\` with:
- \`runs-on: ubuntu-latest\`
- Appropriate setup action for the runtime (setup-node, setup-ruby, setup-python, etc.)
- The same test command verified in B5
- Trigger: push + pull_request

If non-GitHub CI detected → skip CI generation with note: "Detected {provider} — CI pipeline generation supports GitHub Actions only. Add test step to your existing pipeline manually."

### B6. Create TESTING.md

First check: If TESTING.md already exists → read it and update/append rather than overwriting. Never destroy existing content.

Write TESTING.md with:
- Philosophy: "100% test coverage is the key to great vibe coding. Tests let you move fast, trust your instincts, and ship with confidence — without them, vibe coding is just yolo coding. With tests, it's a superpower."
- Framework name and version
- How to run tests (the verified command from B5)
- Test layers: Unit tests (what, where, when), Integration tests, Smoke tests, E2E tests
- Conventions: file naming, assertion style, setup/teardown patterns

### B7. Update CLAUDE.md

First check: If CLAUDE.md already has a \`## Testing\` section → skip. Don't duplicate.

Append a \`## Testing\` section:
- Run command and test directory
- Reference to TESTING.md
- Test expectations:
  - 100% test coverage is the goal — tests make vibe coding safe
  - When writing new functions, write a corresponding test
  - When fixing a bug, write a regression test
  - When adding error handling, write a test that triggers the error
  - When adding a conditional (if/else, switch), write tests for BOTH paths
  - Never commit code that makes existing tests fail

### B8. Commit

\`\`\`bash
git status --porcelain
\`\`\`

Only commit if there are changes. Stage all bootstrap files (config, test directory, TESTING.md, CLAUDE.md, .github/workflows/test.yml if created):
\`git commit -m "chore: bootstrap test framework ({framework name})"\`

### Test Framework Detection

Before analyzing coverage, detect the project's test framework:

1. **Read CLAUDE.md** — look for a \`## Testing\` section with test command and framework name. If found, use that as the authoritative source.
2. **If CLAUDE.md has no testing section, auto-detect:**

\`\`\`bash
# Detect project runtime
[ -f Gemfile ] && echo "RUNTIME:ruby"
[ -f package.json ] && echo "RUNTIME:node"
[ -f requirements.txt ] || [ -f pyproject.toml ] && echo "RUNTIME:python"
[ -f go.mod ] && echo "RUNTIME:go"
[ -f Cargo.toml ] && echo "RUNTIME:rust"

ls -d test/ tests/ spec/ __tests__/ cypress/ e2e/ 2>/dev/null

  sections.push(`
${traceSource}

${traceStep1}
2. **Trace data flow.** Starting from each entry point (route handler, exported function, event listener, component render), follow the data through every branch:
   - Where does input come from? (request params, props, database, API call)
   - What transforms it? (validation, mapping, computation)
   - Where does it go? (database write, API response, rendered output, side effect)
   - What can go wrong at each step? (null/undefined, invalid input, network failure, empty collection)
3. **Diagram the execution.** For each changed file, draw an ASCII diagram showing:
   - Every function/method that was added or modified
   - Every conditional branch (if/else, switch, ternary, guard clause, early return)
   - Every error path (try/catch, rescue, error boundary, fallback)
   - Every call to another function (trace into it — does IT have untested branches?)
   - Every edge: what happens with null input? Empty array? Invalid type?

This is the critical step — you're building a map of every line of code that can execute differently based on input. Every branch in this diagram needs a test.`);

  // ── User flow coverage (shared) ──
  sections.push(`
**${mode === 'ship' ? '2' : 'Step 2'}. Map user flows, interactions, and error states:**

Code coverage isn't enough — you need to cover how real users interact with the changed code. For each changed feature, think through:

- **User flows:** What sequence of actions does a user take that touches this code? Map the full journey (e.g., "user clicks 'Pay' → form validates → API call → success/failure screen"). Each step in the journey needs a test.
- **Interaction edge cases:** What happens when the user does something unexpected?
  - Double-click/rapid resubmit
  - Navigate away mid-operation (back button, close tab, click another link)
  - Submit with stale data (page sat open for 30 minutes, session expired)
  - Slow connection (API takes 10 seconds — what does the user see?)
  - Concurrent actions (two tabs, same form)
- **Error states the user can see:** For every error the code handles, what does the user actually experience?
  - Is there a clear error message or a silent failure?
  - Can the user recover (retry, go back, fix input) or are they stuck?
  - What happens with no network? With a 500 from the API? With invalid data from the server?
- **Empty/zero/boundary states:** What does the UI show with zero results? With 10,000 results? With a single character input? With maximum-length input?

Add these to your diagram alongside the code branches. A user flow with no test is just as much a gap as an untested if/else.`);

  sections.push(`
**${mode === 'ship' ? '3' : 'Step 3'}. Check each branch against existing tests:**

Go through your diagram branch by branch — both code paths AND user flows. For each one, search for a test that exercises it:
- Function \`processPayment()\` → look for \`billing.test.ts\`, \`billing.spec.ts\`, \`test/billing_test.rb\`
- An if/else → look for tests covering BOTH the true AND false path
- An error handler → look for a test that triggers that specific error condition
- A call to \`helperFn()\` that has its own branches → those branches need tests too
- A user flow → look for an integration or E2E test that walks through the journey
- An interaction edge case → look for a test that simulates the unexpected action

- ★★★  Tests behavior with edge cases AND error paths

### E2E Test Decision Matrix

When checking each branch, also determine whether a unit test or E2E/integration test is the right tool:

**RECOMMEND E2E (mark as [→E2E] in the diagram):**
- Common user flow spanning 3+ components/services (e.g., signup → verify email → first login)
- Integration point where mocking hides real failures (e.g., API → queue → worker → DB)
- Auth/payment/data-destruction flows — too important to trust unit tests alone

**RECOMMEND EVAL (mark as [→EVAL] in the diagram):**
- Critical LLM call that needs a quality eval (e.g., prompt change → test output still meets quality bar)
- Changes to prompt templates, system instructions, or tool definitions

**STICK WITH UNIT TESTS:**
- Pure function with clear inputs/outputs
- Internal helper with no side effects
- Edge case of a single function (null input, empty array)
- Obscure/rare flow that isn't customer-facing`);

### REGRESSION RULE (mandatory)

**IRON RULE:** When the coverage audit identifies a REGRESSION — code that previously worked but the diff broke — a regression test is ${mode === 'plan' ? 'added to the plan as a critical requirement' : 'written immediately'}. No AskUserQuestion. No skipping. Regressions are the highest-priority test because they prove something broke.

A regression is when:
- The diff modifies existing behavior (not new code)
- The existing test suite (if any) doesn't cover the changed path
- The change introduces a new failure mode for existing callers

When uncertain whether a change is a regression, err on the side of writing the test.${mode !== 'plan' ? '\n\nFormat: commit as `test: regression test for {what broke}`' : ''}`);

If test framework detected (or bootstrapped in Step 2.5):
- Prioritize error handlers and edge cases first (happy paths are more likely already tested)
- Read 2-3 existing test files to match conventions exactly
- Generate unit tests. Mock all external dependencies (DB, API, Redis).
- For paths marked [→E2E]: generate integration/E2E tests using the project's E2E framework (Playwright, Cypress, Capybara, etc.)
- For paths marked [→EVAL]: generate eval tests using the project's eval framework, or flag for manual eval if none exists
- Write tests that exercise the specific uncovered path with real assertions
- Run each test. Passes → commit as \`test: coverage for {feature}\`
- Fails → fix once. Still fails → revert, note gap in diagram.

Caps: 30 code paths max, 20 tests generated max (code + user flow combined), 2-min per-test exploration cap.

Using the coverage percentage from the diagram in substep 4 (the \`COVERAGE: X/Y (Z%)\` line):

- **>= target:** Pass. "Coverage gate: PASS ({X}%)." Continue.
- **>= minimum, < target:** Use AskUserQuestion:
  - "AI-assessed coverage is {X}%. {N} code paths are untested. Target is {target}%."
  - RECOMMENDATION: Choose A because untested code paths are where production bugs hide.
  - Options:
    A) Generate more tests for remaining gaps (recommended)
    B) Ship anyway — I accept the coverage risk
    C) These paths don't need tests — mark as intentionally uncovered
  - If A: Loop back to substep 5 (generate tests) targeting the remaining gaps. After second pass, if still below target, present AskUserQuestion again with updated numbers. Maximum 2 generation passes total.
  - If B: Continue. Include in PR body: "Coverage gate: {X}% — user accepted risk."
  - If C: Continue. Include in PR body: "Coverage gate: {X}% — {N} paths intentionally uncovered."

- **< minimum:** Use AskUserQuestion:
  - "AI-assessed coverage is critically low ({X}%). {N} of {M} code paths have no tests. Minimum threshold is {minimum}%."
  - RECOMMENDATION: Choose A because less than {minimum}% means more code is untested than tested.
  - Options:
    A) Generate tests for remaining gaps (recommended)
    B) Override — ship with low coverage (I understand the risk)
  - If A: Loop back to substep 5. Maximum 2 passes. If still below minimum after 2 passes, present the override choice again.
  - If B: Continue. Include in PR body: "Coverage gate: OVERRIDDEN at {X}%."

After producing the coverage diagram, check the coverage percentage. Read CLAUDE.md for a \`## Test Coverage\` section with a \`Minimum:\` field. If not found, use default: 60%.

Consider writing tests before running /ship.

This is INFORMATIONAL — does not block /review. But it makes low coverage visible early so the developer can address it before reaching the /ship coverage gate.
