/**
|
||
* Manual E2E Testing Checklist:
|
||
*
|
||
* □ Start dev server: npm run dev
|
||
* □ Open /share?url=<instagram-url>
|
||
* □ Click "Extract Recipe"
|
||
* □ Verify logs show:
|
||
* - 🚀 Starting extraction
|
||
* - ℹ️ Loading Instagram page
|
||
* - 📦 Trying extraction method: Embedded JSON (or other methods)
|
||
* - ✅ Success message
|
||
* - Recipe displays correctly
|
||
* □ Test with problematic URL (should show retries):
|
||
* - 🔄 Retry messages appear
|
||
* - Multiple methods attempted
|
||
* □ Test with invalid URL:
|
||
* - ❌ Error messages appear
|
||
* - No crash or hang
|
||
* □ Verify current method indicator:
|
||
* - Blue badge appears during extraction
|
||
* - Shows correct method name
|
||
* - Disappears when complete
|
||
* □ Check log colors:
|
||
* - Success = green
|
||
* - Errors = red
|
||
* - Retries = yellow
|
||
* - Methods = blue
