Generate Tests

Generate comprehensive unit tests for the specified module or function. Follow the project's existing test patterns and conventions.

Context

  • •Test framework: Vitest
  • •Test file naming: *.test.ts colocated with source
  • •Packages: @yubot/shared, @yubot/backend, @yubot/agent-runtime, @yubot/mobile
  • •Run tests: bun run test (all) or bun --filter <package> test (single package)

Steps

  1. •Read the target module/function specified by the user
  2. •Identify the public API, edge cases, and error conditions
  3. •Read 1-2 existing test files to match the project's testing style:
    • •packages/backend/src/server.test.ts — Fastify server.inject() pattern
    • •packages/shared/src/index.test.ts — simple assertion pattern
  4. •Generate tests covering:
    • •Happy path for each public function/method
    • •Edge cases (empty input, null, boundary values)
    • •Error conditions (invalid input, thrown exceptions)
    • •For agent tools: mock execute params, verify output shape and side effects
  5. •Write the test file next to the source file (e.g., foo.ts → foo.test.ts)
  6. •Run bun --filter <package> test to verify the new tests pass

Output Format

Write the test file and report:

  • •Number of test cases generated
  • •Coverage areas (happy path, edge cases, errors)
  • •Any tests that need manual review
