# Testing Strategy
## Overview
This document outlines the testing strategy for the Memory Bank MCP project.
## Testing Approach
The Memory Bank MCP project follows a comprehensive testing approach that includes:
1. **Unit Testing**: Testing individual components in isolation
2. **Integration Testing**: Testing the interaction between components
3. **Error Handling Testing**: Testing how the system handles error conditions
4. **Edge Case Testing**: Testing boundary conditions and unusual scenarios
## Testing Framework
The project uses **Bun's built-in test runner** for all tests. This decision was made to:
- Leverage Bun's speed and efficiency
- Maintain consistency with the build tooling
- Simplify the development environment
- Reduce dependencies
## Test Organization
Tests are organized in the `src/__tests__` directory, with test files named according to the component they test:
- `fileUtils.test.ts`: Tests for the FileUtils class
- `memoryBankManager.test.ts`: Tests for the MemoryBankManager class
- `progressTracker.test.ts`: Tests for the ProgressTracker class
- `clinerules-integration.test.ts`: Tests for the clinerules integration
## Test Patterns
### Setup and Teardown
Each test file uses `beforeEach` and `afterEach` hooks to:
1. Create temporary test directories
2. Initialize test objects
3. Clean up after tests
Example:
```typescript
beforeEach(async () => {
// Create temporary directory
await fs.ensureDir(tempDir);
// Initialize test objects
testObject = new TestClass();
});
afterEach(async () => {
// Clean up
await fs.remove(tempDir);
});
```
### Asynchronous Testing
Asynchronous operations are tested using async/await:
```typescript
test('Should perform async operation', async () => {
const result = await asyncOperation();
expect(result).toBe(expectedValue);
});
```
### Event Testing
Events are tested using promises:
```typescript
test('Should emit event', async () => {
return new Promise<void>((resolve) => {
emitter.on('event', (data) => {
expect(data).toBe(expectedValue);
resolve();
});
emitter.emit('event', value);
});
});
```
### Error Testing
Error conditions are tested using try/catch blocks:
```typescript
test('Should handle errors', async () => {
try {
await operationThatShouldFail();
// Should not reach here
expect(true).toBe(false);
} catch (error) {
expect(error).toBeTruthy();
}
});
```
## Running Tests
To run all tests:
```bash
bun test
```
To run tests with coverage:
```bash
bun test --coverage
```
To run a specific test file:
```bash
bun test src/__tests__/fileUtils.test.ts
```
## Coverage Goals
The project aims for:
- **Function Coverage**: 95%+
- **Line Coverage**: 90%+
## Continuous Integration
Future plans include setting up a CI/CD pipeline to:
1. Run tests automatically on each commit
2. Generate coverage reports
3. Fail builds if coverage drops below thresholds
4. Ensure all tests pass before merging changes
## Test Maintenance
Tests should be maintained alongside code changes:
1. When adding new features, add corresponding tests
2. When fixing bugs, add regression tests
3. When refactoring code, update affected tests
4. Regularly review and improve test coverage
