Playwright Best Practices
CLI Context: Prevent Context Overflow
When running Playwright tests from Claude Code or any CLI agent, always use minimal reporters to prevent verbose output from consuming the context window.

npx playwright test --reporter=line
npx playwright test --reporter=dot
# BAD: Default reporter generates thousands of lines, floods context
npx playwright test
Configure playwright.config.ts to use minimal reporters by default when CI or CLAUDE env vars are set:
