Generate Tests

Create comprehensive tests for the specified code.

Analysis Steps

1. Identify the code to test (file, function, or recent changes)
2. Understand existing test patterns in the project
3. Determine test framework in use (Jest, Pytest, Go test, etc.)
4. Analyze code for testable behaviors

Test Categories

Unit Tests

• Test individual functions/methods in isolation
• Mock dependencies
• Cover happy path and edge cases

Edge Cases to Cover

• Empty inputs (null, undefined, [], "")
• Boundary values (0, -1, MAX_INT)
• Invalid inputs (wrong types, malformed data)
• Error conditions (network failure, timeout)

Test Structure

describe('ComponentName', () => {
  describe('methodName', () => {
    it('should [expected behavior] when [condition]', () => {
      // Arrange
      // Act
      // Assert
    });
  });
});

Output Format

1. Test file - Complete, runnable test file
2. Coverage notes - What scenarios are tested
3. Missing coverage - What couldn't be easily tested and why

Test Quality Checklist

• Tests are independent (no shared state)
• Test names describe behavior, not implementation
• Each test has a single assertion focus
• Mocks are minimal and realistic
• Edge cases are covered
• Tests run fast (< 100ms each)

Run Verification

After generating tests, offer to:

1. Run the tests
2. Check coverage
3. Identify untested code paths
