## Common Testing Pitfalls and Solutions
- **Complex Library Mocking**
- **Problem**: Trying to create full mocks of complex libraries like Commander.js can be error-prone
- **Solution**: Instead of mocking the entire library, test the command handlers directly by calling your action handlers with the expected arguments
```javascript
// ❌ DON'T: Create complex mocks of Commander.js
class MockCommand {
constructor() { /* Complex mock implementation */ }
option() { /* ... */ }
action() { /* ... */ }
// Many methods to implement
}
// ✅ DO: Test the command handlers directly
test('should use default PRD path when no arguments provided', async () => {
// Call the action handler directly with the right params
await parsePrdAction(undefined, { numTasks: '10', output: 'tasks/tasks.json' });
// Assert on behavior
expect(mockParsePRD).toHaveBeenCalledWith('scripts/prd.txt', 'tasks/tasks.json', 10);
});
```
- **ES Module Mocking Challenges**
- **Problem**: ES modules don't support `require()` and imports are read-only
- **Solution**: Use Jest's module factory pattern and ensure mocks are defined before imports
```javascript
// ❌ DON'T: Try to modify imported modules
import { detectCamelCaseFlags } from '../../scripts/modules/utils.js';
detectCamelCaseFlags = jest.fn(); // Error: Assignment to constant variable
// ❌ DON'T: Try to use require with ES modules
const utils = require('../../scripts/modules/utils.js'); // Error in ES modules
// ✅ DO: Use Jest module factory pattern
jest.mock('../../scripts/modules/utils.js', () => ({
detectCamelCaseFlags: jest.fn(),
toKebabCase: jest.fn()
}));
// Import after mocks are defined
import { detectCamelCaseFlags } from '../../scripts/modules/utils.js';
```
- **Function Redeclaration Errors**
- **Problem**: Declaring the same function twice in a test file causes errors
- **Solution**: Use different function names or create local test-specific implementations
```javascript
// ❌ DON'T: Redefine imported functions with the same name
import { detectCamelCaseFlags } from '../../scripts/modules/utils.js';
function detectCamelCaseFlags() { /* Test implementation */ }
// Error: Identifier has already been declared
// ✅ DO: Use a different name for test implementations
function testDetectCamelCaseFlags() { /* Test implementation */ }
```
- **Console.log Circular References**
- **Problem**: Creating infinite recursion by spying on console.log while also allowing it to log
- **Solution**: Implement a mock that doesn't call the original function
```javascript
// ❌ DON'T: Create circular references with console.log
const mockConsoleLog = jest.spyOn(console, 'log');
mockConsoleLog.mockImplementation(console.log); // Creates infinite recursion
// ✅ DO: Use a non-recursive mock implementation
const mockConsoleLog = jest.spyOn(console, 'log').mockImplementation(() => {});
```
- **Mock Function Method Issues**
- **Problem**: Trying to use jest.fn() methods on imported functions that aren't properly mocked
- **Solution**: Create explicit jest.fn() mocks for functions you need to call jest methods on
```javascript
// ❌ DON'T: Try to use jest methods on imported functions without proper mocking
import { parsePRD } from '../../scripts/modules/task-manager.js';
parsePRD.mockClear(); // Error: parsePRD.mockClear is not a function
// ✅ DO: Create proper jest.fn() mocks
const mockParsePRD = jest.fn().mockResolvedValue(undefined);
jest.mock('../../scripts/modules/task-manager.js', () => ({
parsePRD: mockParsePRD
}));
// Now you can use:
mockParsePRD.mockClear();
```
- **EventEmitter Max Listeners Warning**
- **Problem**: Commander.js adds many listeners in complex mocks, causing warnings
- **Solution**: Either increase the max listeners limit or avoid deep mocking
```javascript
// Option 1: Increase max listeners if you must mock Commander
class MockCommand extends EventEmitter {
constructor() {
super();
this.setMaxListeners(20); // Avoid MaxListenersExceededWarning
}
}
// Option 2 (preferred): Test command handlers directly instead
// (as shown in the first example)
```
- **Test Isolation Issues**
- **Problem**: Tests affecting each other due to shared mock state
- **Solution**: Reset all mocks in beforeEach and use separate test-specific mocks
```javascript
// ❌ DON'T: Allow mock state to persist between tests
const globalMock = jest.fn().mockReturnValue('test');
// ✅ DO: Clear mocks before each test
beforeEach(() => {
jest.clearAllMocks();
// Set up test-specific mock behavior
mockFunction.mockReturnValue('test-specific value');
});
```

# Task ID: 30
# Title: Enhance parse-prd Command to Support Default PRD Path
# Status: pending
# Dependencies: None
# Priority: medium
# Description: Modify the parse-prd command to automatically use a default PRD path when no path is explicitly provided, improving user experience by reducing the need for manual path specification.
# Details:
Currently, the parse-prd command requires users to explicitly specify the path to the PRD document. This enhancement should:
1. Implement a default PRD path configuration that can be set in the application settings or configuration file.
2. Update the parse-prd command to check for this default path when no path argument is provided.
3. Add a configuration option that allows users to set/update the default PRD path through a command like `config set default-prd-path <path>`.
4. Ensure backward compatibility by maintaining support for explicit path specification.
5. Add appropriate error handling for cases where the default path is not set or the file doesn't exist.
6. Update the command's help text to indicate that a default path will be used if none is specified.
7. Consider implementing path validation to ensure the default path points to a valid PRD document.
8. If multiple PRD formats are supported (Markdown, PDF, etc.), ensure the default path handling works with all supported formats.
9. Add logging for default path usage to help with debugging and usage analytics.
# Test Strategy:
1. Unit tests:
- Test that the command correctly uses the default path when no path is provided
- Test that explicit paths override the default path
- Test error handling when default path is not set
- Test error handling when default path is set but file doesn't exist
2. Integration tests:
- Test the full workflow of setting a default path and then using the parse-prd command without arguments
- Test with various file formats if multiple are supported
3. Manual testing:
- Verify the command works in a real environment with actual PRD documents
- Test the user experience of setting and using default paths
- Verify help text correctly explains the default path behavior
4. Edge cases to test:
- Relative vs. absolute paths for default path setting
- Path with special characters or spaces
- Very long paths approaching system limits
- Permissions issues with the default path location
