Testing

Tests the specific feature or bug fix implemented in the current session. NOT full E2E testing - focused on the session's work.

Requirements

• Active session with implemented changes
• Implementation phase completed
• Working Dir available (for starting app)
• If no active session: STOP and ask user for session path

Execution Steps

1. Read session context:

   • Read _overview.md to understand what was implemented
   • Review implementation docs to identify what needs testing

2. Determine test strategy:

   • Frontend changes -> Browser testing
   • Backend changes -> API testing via curl/httpie
   • Full-stack -> Both approaches

3. Select browser testing tool (if frontend testing needed):

   Choose the most suitable tool for your needs:

   Tool	Best For	Setup
   chrome-devtools MCP	Quick inspection, console access	Add to .mcp.json
   Puppeteer	Scripted browser automation	npx puppeteer
   Playwright	Cross-browser testing, screenshots	npx playwright

   Recommendation:

   • Simple UI verification -> chrome-devtools MCP
   • Complex interactions -> Puppeteer or Playwright
   • Need screenshots/traces -> Playwright

   If adding MCP: After modifying .mcp.json, signal continue to restart the agent process (MCP doesn't hot-reload).

4. Start the application:

   • Read project's .samocode file or README for startup instructions
   • Follow project-specific setup commands
   • Verify app is running (check ports, health endpoints)
   • If fails to start -> document error, signal blocked

5. Execute feature tests:

   Browser testing:

   • Navigate to relevant page
   • Interact with new/modified UI elements
   • Verify expected behavior
   • Check console for errors

   API testing:

   # Example: Test endpoint
   curl -X POST http://localhost:8000/api/endpoint \
     -H "Content-Type: application/json" \
     -d '{"test": "data"}'
   

   • Use project-specific auth if needed (check .samocode or README)
   • Verify response codes and data

6. Smoke test (side effect):

   • App started successfully = smoke test passed
   • No crashes during feature test = smoke test passed

7. Document results:

   Create [SESSION_PATH]/[TIMESTAMP_FILE]-test-[feature-slug].md:

   # Test: [feature name]
   Date: [TIMESTAMP_LOG]
   
   ## What Was Tested
   [Brief description of implemented feature]
   
   ## Test Environment
   - Working Dir: [path]
   - App Status: [running/failed to start]
   - Testing Tools: [chrome-devtools/puppeteer/playwright/curl]
   
   ## Test Steps
   1. [Step and result]
   2. [Step and result]
   ...
   
   ## Results
   - Feature Test: [PASS/FAIL]
   - Smoke Test: [PASS/FAIL]
   
   ## Issues Found
   [None or list of issues]
   

8. Update session:

   • Edit _overview.md:
     • Flow Log: - [TIMESTAMP_ITERATION] Feature tested: [result] -> [filename].md
     • Files: - [filename].md - Test report
   • Commit (if git repo): cd [SESSION_DIR] && git add . && git commit -m "Test: [feature]"

9. Signal result:

   • Tests PASS -> signal continue, recommend quality phase
   • Tests FAIL -> signal blocked with failure details (don't auto-fix)

Browser Tool Setup

chrome-devtools MCP

Add to .mcp.json:

{
  "mcpServers": {
    "chrome-devtools": {
      "command": "npx",
      "args": ["chrome-devtools-mcp@latest", "--headless=true"]
    }
  }
}

Then signal continue to restart with new MCP.

Puppeteer (via Bash)

# Quick test script
npx puppeteer <<'EOF'
const puppeteer = require('puppeteer');
(async () => {
  const browser = await puppeteer.launch({ headless: true });
  const page = await browser.newPage();
  await page.goto('http://localhost:3000');
  // ... test steps
  await browser.close();
})();
EOF

Playwright (via Bash)

# Quick test
npx playwright test --headed=false

# Or inline script
npx playwright <<'EOF'
const { chromium } = require('playwright');
(async () => {
  const browser = await chromium.launch();
  const page = await browser.newPage();
  await page.goto('http://localhost:3000');
  await page.screenshot({ path: 'test.png' });
  await browser.close();
})();
EOF

Edge Cases

• Working Dir not in _overview.md -> Check project .samocode file for MAIN_REPO, or ask user
• App fails to start -> Document in test report, signal blocked
• MCP not available -> Use Puppeteer/Playwright via bash instead
• Can't determine what to test -> Review implementation docs, ask if unclear
• No implementation phase completed -> Signal blocked (nothing to test)

Important Notes

• Test ONLY the session's implemented work
• Don't attempt to fix failures automatically - signal blocked instead
• Document everything for human review
• Smoke test happens naturally (app start + no crashes)
• Read project .samocode file or README for project-specific setup instructions
