Generate Test Cases

Generate comprehensive test cases automatically

Instructions

1. **Target Analysis and Scope Definition**

• Parse target file or function from arguments: `$ARGUMENTS`
• If no target specified, analyze current directory and prompt for specific target
• Examine the target code structure, dependencies, and complexity
• Identify function signatures, parameters, return types, and side effects
• Determine testing scope (unit, integration, or both)

2. **Code Structure Analysis**

• Analyze function logic, branching, and control flow
• Identify input validation, error handling, and edge cases
• Examine external dependencies, API calls, and database interactions
• Review data transformations and business logic
• Identify async operations and error scenarios

3. **Test Case Generation Strategy**

• Generate positive test cases for normal operation flows
• Create negative test cases for error conditions and invalid inputs
• Generate edge cases for boundary conditions and limits
• Create integration test cases for external dependencies
• Generate performance test cases for complex operations

4. **Unit Test Implementation**

• Create test file following project naming conventions
• Set up test framework imports and configuration
• Generate test suites organized by functionality
• Create comprehensive test cases with descriptive names
• Implement proper setup and teardown for each test

5. **Mock and Stub Generation**

• Identify external dependencies requiring mocking
• Generate mock implementations for APIs and services
• Create stub data for database and file system operations
• Set up spy functions for monitoring function calls
• Configure mock return values and error scenarios

6. **Data-Driven Test Generation**

• Create test data sets for various input scenarios
• Generate parameterized tests for multiple input combinations
• Create fixtures for complex data structures
• Set up test data factories for consistent data generation
• Generate property-based test cases for comprehensive coverage

7. **Integration Test Scenarios**

• Generate tests for component interactions
• Create end-to-end workflow test cases
• Generate API integration test scenarios
• Create database integration tests with real data
• Generate cross-module integration test cases

8. **Error Handling and Exception Testing**

• Generate tests for all error conditions and exceptions
• Create tests for timeout and network failure scenarios
• Generate tests for invalid input validation
• Create tests for resource exhaustion and limits
• Generate tests for concurrent access and race conditions

9. **Test Quality and Coverage**

• Ensure comprehensive code coverage for target functions
• Generate tests for all code branches and paths
• Create tests for both success and failure scenarios
• Validate test assertions are meaningful and specific
• Ensure tests are isolated and independent

10. **Test Documentation and Maintenance**

• Generate clear test descriptions and documentation
• Create comments explaining complex test scenarios
• Document test data requirements and setup procedures
• Generate test maintenance guidelines and best practices
• Create test execution and debugging instructions
• Validate generated tests execute successfully and provide meaningful feedback
