Analyzing Sentry Logs for Playwright

REPRODUCTION BLUEPRINT
Environment: https://app.example.com/dashboard | Chrome 120 | 1920x1080
Initial State: Authenticated user (ID: user_123), dark_mode=true
Execution Steps:
1. Click "Export Data" button
2. Select "CSV Format" from dropdown
3. Submit form triggers POST /api/export
Assertion Point: ReferenceError: exportManager is not defined
Mocking Requirements: Mock POST /api/export to return 500 Internal Server Error

Progress:

• Extract environment context from Tags
• Identify initial application state from Context
• Map breadcrumbs to chronological actions
• Locate the exact error point
• Flag required API mocks from failed requests
• Format as structured blueprint

Step-by-Step Process

1. Parse Environment Data

   • Extract URL, browser, OS from Tags section
   • Note viewport size if available
   • Capture release version

2. Analyze Application State

   • User authentication status from Context
   • Feature flags or configuration from Tags
   • LocalStorage/Cookie dependencies

3. Convert Breadcrumbs to Actions

   • Focus on: ui.click, ui.input, navigation, http
   • Map UI events to user actions
   • Note failed HTTP requests (4xx/5xx status)

4. Identify Assertion Point

   • Extract exact exception name and message
   • Note line numbers from stack trace
   • Determine observable failure state

5. Document Mock Requirements

   • List failed API endpoints
   • Include expected error responses
   • Note timing dependencies

Example 1: Input: Sentry log with breadcrumbs showing navigation to /checkout, form submission, and TypeError on payment processing Output:

REPRODUCTION BLUEPRINT
Environment: https://shop.com/checkout | Firefox 118 | Mobile 375x667
Initial State: Cart contains 2 items, guest checkout
Execution Steps:
1. Navigate to checkout page
2. Fill shipping form fields
3. Click "Continue to Payment"
4. Enter credit card details
5. Submit payment form
Assertion Point: TypeError: Cannot read property 'validate' of null
Mocking Requirements: Mock POST /api/payment/validate to return 422 validation error

Example 2: Input: Insufficient breadcrumb data, only shows final error without user actions Output:

REPRODUCTION BLUEPRINT
Environment: https://admin.app.com/users | Chrome 119 | 1440x900
Initial State: Admin user authenticated
Execution Steps:
INSUFFICIENT DATA FOR: User interaction sequence leading to error
Assertion Point: ReferenceError: userManager is not defined at line 247
Mocking Requirements: None identified
