audit: Test coverage and quality

Audit: Testing

Evaluate test coverage, quality, and practices.

Coverage Analysis

1. Line Coverage - What percentage?
2. Branch Coverage - All paths tested?
3. Critical Paths - Auth, payments, core logic covered?
4. Untested Code - List files/functions with 0% coverage

Test Quality

1. Test Independence

   • Tests isolated?
   • Order-dependent tests?
   • Shared mutable state?

2. Test Clarity

   • Descriptive names?
   • Arrange-Act-Assert pattern?
   • Single assertion principle?

3. Test Reliability

   • Flaky tests?
   • Time-dependent tests?
   • External dependencies mocked?

Missing Tests

1. Edge Cases - Null, empty, boundary values
2. Error Paths - Exception handling
3. Security Tests - Auth bypass, injection
4. Integration Tests - Component interaction
5. Performance Tests - Load, stress

Anti-Patterns

• Testing implementation details
• Excessive mocking
• Brittle assertions
• Slow tests
• Ignored tests
