Test Generator

Generate comprehensive tests with advanced testing strategies, scenario generation, and edge case identification.

When to Activate

• User asks to write tests
• User mentions test coverage
• User wants unit, integration, or e2e tests
• After implementing new features (suggest tests)
• User asks about testing a specific file or function

Quick Process

1. Analyze Code: Understand structure and dependencies
2. Select Strategy: Choose testing approach based on code type
3. Generate Tests: Create tests with appropriate framework
4. Identify Edge Cases: Boundary conditions and error handling
5. Output Files: Write test files with full coverage

Options

Option	Values	Default
--framework	jest, vitest, pytest, cypress, playwright	auto-detect
--type	unit, integration, e2e, all	unit
--strategy	standard, scenario, property, mutation	standard
--requirements	User stories for scenario generation	(none)

Strategies

• Standard: Traditional unit testing with assertions
• Scenario: Behavior-driven from user stories (Given-When-Then)
• Property: Property-based testing for pure functions
• Mutation: Mutation testing to verify test quality

Edge Case Emphasis

Always identifies:

• Boundary values and null/undefined handling
• Overflow/underflow conditions
• Security edge cases (injection, XSS)
• Concurrency and race conditions

Delegation

Invoke test-writer agent with:

• paths: Files to test
• framework: Testing framework
• testType: Testing strategy
• requirements: User stories (if provided)

For complex scenarios, coordinate with context-loader and security-analyzer.

Examples

"Write tests for src/utils/validator.ts"
"Add integration tests for the API endpoints"
"Generate e2e tests for checkout flow"
"I need property-based tests for this pure function"
