fix(config): Improve config manager flexibility & test mocks

Refactored `config-manager.js` to handle different execution contexts (CLI vs. MCP) and fixed related Jest tests.

- Modified `readConfig` and `writeConfig` to accept an optional `explicitRoot` parameter, allowing explicit path specification (e.g., from MCP) while retaining automatic project root finding for CLI usage.

- Updated getter/setter functions (`getMainProvider`, `setMainModel`, etc.) to accept and propagate the `explicitRoot`.

- Resolved Jest testing issues for dynamic imports by using `jest.unstable_mockModule` for `fs` and `chalk` dependencies *before* the dynamic `import()`.

- Corrected console error assertions in tests to match exact logged messages.

- Updated `.cursor/rules/tests.mdc` with guidelines for `jest.unstable_mockModule` and precise console assertions.

- Imported functions may not use your mocked dependencies even with proper jest.mock() setup
- ES module exports are read-only properties (cannot be reassigned during tests)
- **Mocking Entire Modules**
- **Mocking Modules Statically Imported**
- For modules imported with standard `import` statements at the top level:
- Use `jest.mock('path/to/module', factory)` **before** any imports.
- Jest hoists these mocks.
- Ensure the factory function returns the mocked structure correctly.
- **Mocking Dependencies for Dynamically Imported Modules**
- **Problem**: Standard `jest.mock()` often fails for dependencies of modules loaded later using dynamic `import('path/to/module')`. The mocks aren't applied correctly when the dynamic import resolves.
- **Solution**: Use `jest.unstable_mockModule(modulePath, factory)` **before** the dynamic `import()` call.
```javascript
// Mock the entire module with custom implementation
jest.mock('../../scripts/modules/task-manager.js', () => {
// Get original implementation for functions you want to preserve
const originalModule = jest.requireActual('../../scripts/modules/task-manager.js');
// Return mix of original and mocked functionality
return {
...originalModule,
generateTaskFiles: jest.fn() // Replace specific functions
};
// 1. Define mock function instances
const mockExistsSync = jest.fn();
const mockReadFileSync = jest.fn();
// ... other mocks
// 2. Mock the dependency module *before* the dynamic import
jest.unstable_mockModule('fs', () => ({
__esModule: true, // Important for ES module mocks
// Mock named exports
existsSync: mockExistsSync,
readFileSync: mockReadFileSync,
// Mock default export if necessary
// default: { ... }
}));
// 3. Dynamically import the module under test (e.g., in beforeAll or test case)
let moduleUnderTest;
beforeAll(async () => {
// Ensure mocks are reset if needed before import
mockExistsSync.mockReset();
mockReadFileSync.mockReset();
// ... reset other mocks ...
// Import *after* unstable_mockModule is called
moduleUnderTest = await import('../../scripts/modules/module-using-fs.js');
});
// Import after mocks
import * as taskManager from '../../scripts/modules/task-manager.js';
// Now you can use the mock directly
const { generateTaskFiles } = taskManager;
// 4. Now tests can use moduleUnderTest, and its 'fs' calls will hit the mocks
test('should use mocked fs.readFileSync', () => {
mockReadFileSync.mockReturnValue('mock data');
moduleUnderTest.readFileAndProcess();
expect(mockReadFileSync).toHaveBeenCalled();
// ... other assertions
});
```
- ✅ **DO**: Call `jest.unstable_mockModule()` before `await import()`.
- ✅ **DO**: Include `__esModule: true` in the mock factory for ES modules.
- ✅ **DO**: Mock named and default exports as needed within the factory.
- ✅ **DO**: Reset mock functions (`mockFn.mockReset()`) before the dynamic import if they might have been called previously.
- **Mocking Entire Modules (Static Import)**
```javascript
// Mock the entire module with custom implementation for static imports
// ... (existing example remains valid) ...
```
- **Direct Implementation Testing**
- Instead of calling the actual function which may have module-scope reference issues:
```javascript
test('should perform expected actions', () => {
// Setup mocks for this specific test
mockReadJSON.mockImplementationOnce(() => sampleData);
// Manually simulate the function's behavior
const data = mockReadJSON('path/file.json');
mockValidateAndFixDependencies(data, 'path/file.json');
// Skip calling the actual function and verify mocks directly
expect(mockReadJSON).toHaveBeenCalledWith('path/file.json');
expect(mockValidateAndFixDependencies).toHaveBeenCalledWith(data, 'path/file.json');
});
// ... (existing example remains valid) ...
```
- **Avoiding Module Property Assignment**
```javascript
// ❌ DON'T: This causes "Cannot assign to read only property" errors
const utils = await import('../../scripts/modules/utils.js');
utils.readJSON = mockReadJSON; // Error: read-only property
// ✅ DO: Use the module factory pattern in jest.mock()
jest.mock('../../scripts/modules/utils.js', () => ({
readJSON: mockReadJSONFunc,
writeJSON: mockWriteJSONFunc
}));
// ... (existing example remains valid) ...
```
- **Handling Mock Verification Failures**
- If verification like `expect(mockFn).toHaveBeenCalled()` fails:
1. Check that your mock setup is before imports
2. Ensure you're using the right mock instance
3. Verify your test invokes behavior that would call the mock
4. Use `jest.clearAllMocks()` in beforeEach to reset mock state
5. Consider implementing a simpler test that directly verifies mock behavior
- **Full Example Pattern**
```javascript
// 1. Define mock implementations
const mockReadJSON = jest.fn();
const mockValidateAndFixDependencies = jest.fn();
// 2. Mock modules
jest.mock('../../scripts/modules/utils.js', () => ({
readJSON: mockReadJSON,
// Include other functions as needed
}));
jest.mock('../../scripts/modules/dependency-manager.js', () => ({
validateAndFixDependencies: mockValidateAndFixDependencies
}));
// 3. Import after mocks
import * as taskManager from '../../scripts/modules/task-manager.js';
describe('generateTaskFiles function', () => {
beforeEach(() => {
jest.clearAllMocks();
});
test('should generate task files', () => {
// 4. Setup test-specific mock behavior
const sampleData = { tasks: [{ id: 1, title: 'Test' }] };
mockReadJSON.mockReturnValueOnce(sampleData);
// 5. Create direct implementation test
// Instead of calling: taskManager.generateTaskFiles('path', 'dir')
// Simulate reading data
const data = mockReadJSON('path');
expect(mockReadJSON).toHaveBeenCalledWith('path');
// Simulate other operations the function would perform
mockValidateAndFixDependencies(data, 'path');
expect(mockValidateAndFixDependencies).toHaveBeenCalledWith(data, 'path');
});
});
```
1. Check that your mock setup (`jest.mock` or `jest.unstable_mockModule`) is correctly placed **before** imports (static or dynamic).
2. Ensure you're using the right mock instance and it's properly passed to the module.
3. Verify your test invokes behavior that *should* call the mock.
4. Use `jest.clearAllMocks()` or specific `mockFn.mockReset()` in `beforeEach` to prevent state leakage between tests.
5. **Check Console Assertions**: If verifying `console.log`, `console.warn`, or `console.error` calls, ensure your assertion matches the *actual* arguments passed. If the code logs a single formatted string, assert against that single string (using `expect.stringContaining` or exact match), not multiple `expect.stringContaining` arguments.
```javascript
// Example: Code logs console.error(`Error: ${message}. Details: ${details}`)
// ❌ DON'T: Assert multiple arguments if only one is logged
// expect(console.error).toHaveBeenCalledWith(
// expect.stringContaining('Error:'),
// expect.stringContaining('Details:')
// );
// ✅ DO: Assert the single string argument
expect(console.error).toHaveBeenCalledWith(
expect.stringContaining('Error: Specific message. Details: More details')
);
// or for exact match:
expect(console.error).toHaveBeenCalledWith(
'Error: Specific message. Details: More details'
);
```
6. Consider implementing a simpler test that *only* verifies the mock behavior in isolation.

7. Implement client validation to ensure proper initialization
8. Testing approach: Mock API responses to test client creation and error handling
<info added on 2025-04-14T23:02:30.519Z>
Here's additional information for the client factory implementation:
For the client factory implementation:
1. Structure the factory with a modular approach:
```javascript
// ai-client-factory.js
import { createOpenAI } from '@ai-sdk/openai';
import { createAnthropic } from '@ai-sdk/anthropic';
import { createGoogle } from '@ai-sdk/google';
import { createPerplexity } from '@ai-sdk/perplexity';
const clientCache = new Map();
export function createClientInstance(providerName, options = {}) {
// Implementation details below
}
```
2. For OpenAI-compatible providers (Ollama), implement specific configuration:
```javascript
case 'ollama':
const ollamaBaseUrl = process.env.OLLAMA_BASE_URL || 'http://localhost:11434';
return createOpenAI({
baseURL: ollamaBaseUrl,
apiKey: 'ollama', // Ollama doesn't require a real API key
...options
});
```
3. Add provider-specific model mapping:
```javascript
// Model mapping helper
const getModelForProvider = (provider, requestedModel) => {
const modelMappings = {
openai: {
default: 'gpt-3.5-turbo',
// Add other mappings
},
anthropic: {
default: 'claude-3-opus-20240229',
// Add other mappings
},
// Add mappings for other providers
};
return (modelMappings[provider] && modelMappings[provider][requestedModel])
|| modelMappings[provider]?.default
|| requestedModel;
};
```
4. Implement caching with provider+model as key:
```javascript
export function getClient(providerName, model) {
const cacheKey = `${providerName}:${model || 'default'}`;
if (clientCache.has(cacheKey)) {
return clientCache.get(cacheKey);
}
const modelName = getModelForProvider(providerName, model);
const client = createClientInstance(providerName, { model: modelName });
clientCache.set(cacheKey, client);
return client;
}
```
5. Add detailed environment variable validation:
```javascript
function validateEnvironment(provider) {
const requirements = {
openai: ['OPENAI_API_KEY'],
anthropic: ['ANTHROPIC_API_KEY'],
google: ['GOOGLE_API_KEY'],
perplexity: ['PERPLEXITY_API_KEY'],
openrouter: ['OPENROUTER_API_KEY'],
ollama: ['OLLAMA_BASE_URL'],
grok: ['GROK_API_KEY', 'GROK_BASE_URL']
};
const missing = requirements[provider]?.filter(env => !process.env[env]) || [];
if (missing.length > 0) {
throw new Error(`Missing environment variables for ${provider}: ${missing.join(', ')}`);
}
}
```
6. Add Jest test examples:
```javascript
// ai-client-factory.test.js
describe('AI Client Factory', () => {
beforeEach(() => {
// Mock environment variables
process.env.OPENAI_API_KEY = 'test-openai-key';
process.env.ANTHROPIC_API_KEY = 'test-anthropic-key';
// Add other mocks
});
test('creates OpenAI client with correct configuration', () => {
const client = getClient('openai');
expect(client).toBeDefined();
// Add assertions for client configuration
});
test('throws error when environment variables are missing', () => {
delete process.env.OPENAI_API_KEY;
expect(() => getClient('openai')).toThrow(/Missing environment variables/);
});
// Add tests for other providers
});
```

Add Jest test examples:\n```javascript\n// ai-client-factory.test.js\ndescribe('AI Client Factory', () => {\n beforeEach(() => {\n // Mock environment variables\n process.env.OPENAI_API_KEY = 'test-openai-key';\n process.env.ANTHROPIC_API_KEY = 'test-anthropic-key';\n // Add other mocks\n });\n \n test('creates OpenAI client with correct configuration', () => {\n const client = getClient('openai');\n expect(client).toBeDefined();\n // Add assertions for client configuration\n });\n \n test('throws error when environment variables are missing', () => {\n delete process.env.OPENAI_API_KEY;\n expect(() => getClient('openai')).toThrow(/Missing environment variables/);\n });\n \n // Add tests for other providers\n});\n```\n</info added on 2025-04-14T23:02:30.519Z>",
