generate-tests

Generate comprehensive tests for code. Use when user says "write tests for this function", "add unit tests to this file", "generate integration tests for the API", "I need test coverage for this module", or "create e2e tests for the checkout flow".

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

Analyze Code: Understand structure and dependencies
Select Strategy: Choose testing approach based on code type
Generate Tests: Create tests with appropriate framework
Identify Edge Cases: Boundary conditions and error handling
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 agent with:

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

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

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"
