Write Tests

Write comprehensive unit and integration tests with framework-specific best practices: $ARGUMENTS

Current Testing Context

• Test framework: !find . -name "jest.config." -o -name ".test.*" | head -1 && echo "Jest/Vitest detected" || echo "Detect framework"
• Target file: Analysis of $ARGUMENTS for test requirements and complexity
• Project patterns: !find . -name ".test." -o -name ".spec." | head -3 existing test patterns
• Coverage setup: !grep -l "coverage" package.json jest.config.* 2>/dev/null | head -1 || echo "Setup needed"

Task

Execute comprehensive test writing with framework-specific optimizations and best practices:

Test Focus: Use $ARGUMENTS to specify target file, unit tests, integration tests, e2e tests, or component tests Test Writing Framework:

• Code Analysis - Analyze target code structure, identify testable functions, assess dependency complexity, evaluate edge cases
• Test Strategy Design - Plan test organization, design test hierarchies, identify mock requirements, optimize test isolation
• Framework Integration - Setup framework-specific patterns, configure test utilities, implement proper assertions, optimize test performance
• Mock Implementation - Design dependency mocks, implement test doubles, create factory functions, setup async handling
• Test Case Generation - Write unit tests, integration tests, edge cases, error scenarios, performance tests, snapshot tests
• Quality Assurance - Ensure test maintainability, optimize execution speed, validate coverage, implement proper cleanup

Advanced Features: Property-based testing, contract testing, visual regression testing, accessibility testing, performance benchmarking. Framework Support: Jest/Vitest, React Testing Library, Vue Test Utils, Angular TestBed, Cypress, Playwright integration. Output: Comprehensive test suite with unit tests, integration tests, proper mocking, test utilities, and coverage optimization.
