name: testgen description: Generate tests for a file or module using coverage analysis and TDD patterns

$ARGUMENTS

Generate tests by analyzing coverage gaps and applying TDD London School patterns.

1. Analyze gaps: npx @claude-flow/cli@latest hooks coverage-gaps --format table
2. Route for coverage: npx @claude-flow/cli@latest hooks coverage-route --task "$ARGUMENTS"
3. Suggest tests: npx @claude-flow/cli@latest hooks coverage-suggest --path "$ARGUMENTS"

Parse $ARGUMENTS as a file path or module name. Generate tests following these conventions:

• Place tests adjacent to source: src/foo.ts -> src/foo.test.ts
• Use describe/it blocks with descriptive names
• Mock external dependencies
• Cover happy path, edge cases, and error paths

If no arguments, run coverage-gaps to show what needs tests.
