Test Generation

When to Use

Use this skill when writing tests or when asked to add test coverage.

Test Categories

1. Unit Tests

• Test individual functions/methods
• Mock dependencies
• Cover edge cases

2. Integration Tests

• Test component interactions
• Real dependencies when possible
• Database transactions

3. Edge Cases to Cover

• Empty inputs
• Null/undefined values
• Maximum/minimum values
• Invalid types
• Concurrent access
• Network failures

Test Structure (AAA Pattern)

// Arrange - Set up test data and conditions
// Act - Execute the code under test
// Assert - Verify the results

Naming Convention

[methodName]_[scenario]_[expectedResult]

Example: calculateTotal_emptyCart_returnsZero

Coverage Goals

• Statements: 80%+
• Branches: 75%+
• Functions: 90%+
• Lines: 80%+
