description	Provides test design patterns, coverage strategies, and best practices for comprehensive test suite development
version	1.0.0

Overview

This skill provides strategies for test design, test coverage, test organization, and testing best practices across different testing types and frameworks.

Test Coverage Targets

• Critical Code (auth, payment, security): 100%
• Business Logic: 90-100%
• Utilities: 80-90%
• UI Components: 70-80%
• Overall Project: 80%+

Test Types

Unit Tests

• Test individual functions/methods in isolation
• Use mocks for dependencies
• Fast execution (<1ms per test)
• Cover happy path, edge cases, errors

Integration Tests

• Test component interactions
• Use real dependencies where reasonable
• Test API endpoints, database operations
• Moderate execution time

End-to-End Tests

• Test complete user workflows
• Use real system components
• Critical paths only (slower execution)

Test Case Pattern

For each function, create tests for:

1. Happy Path: Normal, expected inputs
2. Edge Cases: Boundary values, empty inputs
3. Error Cases: Invalid inputs, exceptions
4. Special Cases: Nulls, zeros, large values

When to Apply

Use when creating test suites, improving coverage, fixing failing tests, or designing test strategies.
