Testing

This server gives Claude five tools for generating and analyzing tests without leaving the conversation. You can scaffold Jest or Vitest test suites from function signatures, complete with happy path, edge cases, and boundary conditions. It generates mock data for common types like emails and UUIDs, creates realistic API response payloads from schema definitions, and analyzes source code against test files to surface untested functions ranked by complexity. The generate_assertions tool diffs expected versus actual values and writes granular assertion code for you. Useful when you're writing tests alongside implementation or need to quickly populate fixture data for integration tests.
