Generate thorough unit test suites with edge cases, mocking, and coverage for any function or module.

Prompt

Write a comprehensive test suite for [function/module]. Requirements:
- Test the happy path with typical inputs
- Test edge cases: empty inputs, null/undefined, boundary values
- Test error conditions: invalid inputs, network failures, timeouts
- Mock external dependencies (API calls, database, file system)
- Use descriptive test names that explain the expected behavior
- Group related tests with describe blocks
- Add setup/teardown (beforeEach/afterEach) where needed
- Test async operations with proper await/Promise handling
- Verify error messages and error types, not just that errors are thrown
- Include snapshot tests only if output is complex and stable
- Aim for branch coverage, not just line coverage
- Add comments explaining WHY edge cases matter
- Follow AAA pattern: Arrange, Act, Assert

How to Use

Select the function or module code, then apply this prompt. Cursor will analyze the code and generate tests covering all branches. Review generated mocks for correctness.
