Stability Improvement Program
The following best practices are recommended based on Microsoft's official documentation recommendations:
- Element positioning strategy::
- Preferred use of element references in snapshot mode (refID)
- Avoid relying on volatile XPath/CSS selectors
- Adding ARIA tags to key elements improves accessibility
- Exception handling mechanism::
- combiningbrowser_waitEnabling smart waiting (2-5 seconds recommended)
- Setting the operation timeout threshold (configured via the MCP protocol)
- Execution on a regular basisbrowser_snapshotPerform state validation
- Multi-browser compatible::
- Execute critical test cases in Chromium/Firefox/WebKit respectively
- utilization-browserparameter specifies the rendering engine
diagnostic technique::
1. Remove-headless mode for real-time observation of operations
2. AdoptionDEBUG=pw:mcp*Detailed log of environment variable output
3. Screenshots of the visualization model (browser_screenshot) can be used for failure review
