Test Writer Implementation

Create tests for newly implemented feature functionality.

Implementation Checklist

Unit Test Coverage

• Write tests for all public methods and functions

• Verify happy path scenarios produce expected results

• Check that each test validates a single behavior

• Ensure proper use of mocks and stubs for dependencies

• Validate test naming follows project conventions

Integration Tests

• Write tests for component interaction boundaries

• Verify API endpoint request/response contracts

• Check database operations with real or in-memory stores

• Ensure external service integrations use test doubles

• Validate end-to-end workflows across layers

Edge Case Coverage

• Test boundary values (zero, empty, max, min)

• Verify null and undefined input handling

• Check concurrent access and race condition scenarios

• Ensure error paths return appropriate failures

• Validate timeout and retry behavior

Test Data & Fixtures

• Create reusable test fixtures and factories

• Verify test data represents realistic scenarios

• Check for proper test isolation (no shared mutable state)

• Ensure setup and teardown clean up resources

• Validate test determinism (no flaky dependencies)
