Browser Tools
JAT includes browser automation tools in ~/.local/bin/:
| Tool | Purpose |
|---|---|
browser-start.js |
Launch Chrome with DevTools port |
browser-nav.js |
Navigate to URL |
browser-screenshot.js |
Capture screenshot |
browser-eval.js |
Execute JavaScript in page |
browser-pick.js |
Click element by selector |
browser-cookies.js |
Get/set cookies |
browser-wait.js |
Wait for condition |
Steps
STEP 1: Determine What to Test
Based on your recent work, identify:
- URL: What page to open
- Feature: What to test
- Success criteria: How to know it works
If unclear, ask the user.
STEP 2: Open Browser and Navigate
browser-start.js
browser-nav.js --url "http://localhost:5173/tasks"
browser-screenshot.js --output /tmp/verify-initial.png
Show the screenshot and describe what you see.
STEP 3: Test the Feature
Interact with what you built:
# Click elements
browser-pick.js --selector "button.create-task"
# Fill form fields
browser-eval.js "document.querySelector('input[name=title]').value = 'Test'"
# Check for elements
browser-eval.js "!!document.querySelector('.success-message')"
# Wait for content
browser-wait.js --text "Task created"
Take screenshots after each significant action.
STEP 4: Check Console for Errors
browser-eval.js "window.__errors = []; const orig = console.error; console.error = (...a) => { window.__errors.push(a.join(' ')); orig.apply(console, a); }"
# ... test the feature ...
browser-eval.js "window.__errors"
STEP 5: Report Findings
BROWSER VERIFICATION: {TASK_ID}
URL: http://localhost:5173/tasks
Feature: Task creation drawer
[pass] Page loaded successfully
[pass] Button visible and clickable
[pass] Form renders correctly
[pass] No console errors
Screenshots:
/tmp/verify-initial.png
/tmp/verify-after-action.png
If issues found, fix them and re-verify.
After Verification
- Passed: Return to "READY FOR REVIEW" state
- Failed: Fix issues, re-verify, then return to review state
