# Trouble Shotting and Debugging

> Learn how to troubleshoot browser checks.

## Common Issues

<Accordion title="Element Selection Problems">
  **Issue: Elements not found or interactions failing**

  **Solutions**:

  1. Use browser dev tools to test selectors
  2. Add explicit waits for dynamic content
  3. Use more specific or stable selectors
  4. Check for iframe or shadow DOM elements
</Accordion>

<Accordion title="Timing and Race Conditions">
  **Issue: Tests failing due to timing issues**

  **Solutions**:

  1. Use `waitForSelector()` instead of fixed delays
  2. Wait for network requests to complete
  3. Use `waitForLoadState()` for page readiness
  4. Implement proper error handling and retries
</Accordion>

<Accordion title="Authentication and Session Issues">
  **Issue: Login failures or session timeouts**

  **Solutions**:

  1. Verify credentials are correct and active
  2. Handle multi-factor authentication scenarios
  3. Use session storage for authentication state
  4. Test login flow separately from main workflow
</Accordion>

<Accordion title="Performance and Timeout Issues">
  **Issue: Tests timing out or running too slowly**

  **Solutions**:

  1. Optimize page load performance
  2. Increase timeout values for slow operations
  3. Use parallel execution where possible
  4. Monitor and alert on performance degradation
</Accordion>

## Error Handling and Debugging

<Accordion title="Wait Strategies">
  ```typescript theme={null}
  // Wait for specific conditions
  await page.waitForSelector('[data-testid="loading-complete"]')
  await page.waitForURL('**/dashboard')
  await page.waitForFunction(() => window.dataLoaded === true)

  // Wait for network requests
  await page.waitForResponse(response => 
    response.url().includes('/api/user') && response.status() === 200
  )

  // Timeout configuration
  await page.waitForSelector('.slow-element', { timeout: 30000 })
  ```
</Accordion>

<Accordion title="Error Recovery">
  ```typescript theme={null}
  // Graceful error handling
  try {
    await page.click('.optional-popup-close', { timeout: 5000 })
  } catch (error) {
    // Continue if popup doesn't appear
    console.log('No popup to close')
  }

  // Conditional interactions
  const isLoggedIn = await page.locator('.user-menu').isVisible()
  if (!isLoggedIn) {
    await page.click('.login-button')
    // Handle login flow
  }
  ```
</Accordion>
