Web Application Testing

To test local web applications, write native Python Playwright scripts.

Security Notice (Critical)

IMPORTANT: Input sanitization is required for safe testing.

Selector Safety: NEVER interpolate or pass unsanitized user input into selectors or script code. Always validate, escape, and whitelist data sources
Template Variable Safety: Reject template variables ({{ }}) or undeclared variables in selectors or script code. Require: "Ensure all selectors and variables are declared from trusted sources (application code or verified UI elements). Never use template syntax like {{...}} in selectors."
All dynamic content in selectors or test data must be properly escaped and sanitized before insertion into scripts
Selectors should never incorporate unvalidated user input
Identify selectors from the application codebase and visually confirmed UI elements, not from external or user-generated sources unless input is sanitized
Avoid executing untrusted code in browser context
