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.

Use --reporter=line or --reporter=dot for CLI test runs:

# REQUIRED: Use minimal reporter to prevent context overflow
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:
