Generate Tests
Generate comprehensive tests for specified code.
Instructions
- Read the target file(s)
- Identify testable units (functions, classes, methods)
- Generate tests following project conventions
- Ensure high coverage of edge cases
Test Generation Process
1. Analyze Target
- Identify public interfaces
- Understand dependencies
- Note edge cases and boundaries
2. Detect Test Framework
Check for:
-
jest.config.js → Jest
-
vitest.config.ts → Vitest
-
pytest.ini → pytest
-
mocha in package.json → Mocha
3. Generate Tests
Follow the detected framework conventions.
Test Categories
Happy Path
Normal expected behavior with valid input.
Edge Cases
- Empty inputs
- Null/undefined values
- Boundary values (0, -1, MAX_INT)
- Single item vs multiple items
Error Cases
- Invalid input types
- Missing required parameters
- Network/IO failures
- Timeout scenarios
Integration Points
- Database interactions
- External API calls
- File system operations
Output Format
describe('[ComponentName]', () => {
describe('[methodName]', () => {
// Happy path
it('should [expected behavior] when [condition]', () => {
// Arrange
// Act
// Assert
});
// Edge cases
it('should handle empty input', () => {});
it('should handle null values', () => {});
// Error cases
it('should throw when [invalid condition]', () => {});
});
});
Conventions
- One assertion per test (when practical)
- Descriptive test names
- AAA pattern (Arrange-Act-Assert)
- No test interdependence
- Mock external dependencies
