## 🔧 Test Configuration

### Test Dependencies

```xml
<PackageReference Include="Microsoft.NET.Test.Sdk" Version="17.8.0" />
<PackageReference Include="MSTest.TestAdapter" Version="3.1.1" />
<PackageReference Include="MSTest.TestFramework" Version="3.1.1" />
<PackageReference Include="Moq" Version="4.20.70" />
```

### Mock Strategy

Tests use **Moq** for creating test doubles:
- **Service Mocks**: Interface-based mocking for dependency isolation
- **Configuration Mocks**: Options pattern mocking for settings
- **External Dependencies**: File system and network operation mocking

### Test Data Management

- **Isolated Tests**: Each test creates its own data
- **Temporary Files**: Automatic cleanup of test artifacts
- **In-Memory Configuration**: No external configuration dependencies
- **Deterministic Results**: Consistent test outcomes

## 🧩 Advanced Testing Patterns

### 1. Service Integration Testing

```csharp
[TestMethod]
public async Task FullWorkflow_ComprehensiveContextPreparation_IntegratesAllServices()
{
    var unifiedContextService = _serviceProvider.GetRequiredService<IUnifiedContextService>();
    var securityService = _serviceProvider.GetRequiredService<ISecurityService>();
    
    var context = await unifiedContextService.PrepareFullContextAsync(query, filePath, 6000);
    
    Assert.IsTrue(securityService.IsPathSafe(filePath));
    Assert.IsNotNull(context.CurrentCodeAnalysis);
    Assert.IsTrue(context.EstimatedTotalTokens <= 6000);
}
```

### 2. Configuration Validation Testing

```csharp
[TestMethod]
public void Configuration_Validation_WorksWithDataAnnotations()
{
    var config = TestDataBuilder.CreateValidConfiguration();
    var validationResults = ValidateObject(config);
    
    Assert.AreEqual(0, validationResults.Count);
}
```

### 3. Concurrent Operation Testing

```csharp
[TestMethod]
public async Task Performance_ConcurrentOperations_HandleCorrectly()
{
    var tasks = new List<Task<ComprehensiveContext>>();
    
    for (int i = 0; i < 5; i++)
    {
        tasks.Add(unifiedContextService.PrepareFullContextAsync($"query {i}"));
    }
    
    var results = await Task.WhenAll(tasks);
    Assert.AreEqual(5, results.Length);
}
```

## 🎯 Testing Best Practices

### 1. Test Organization
- **AAA Pattern**: Arrange, Act, Assert
- **Descriptive Names**: Clear test method naming
- **Single Responsibility**: One assertion per test
- **Independent Tests**: No test dependencies

### 2. Mock Usage
- **Interface Mocking**: Mock dependencies, not implementations
- **Behavior Verification**: Verify method calls when appropriate
- **Data Isolation**: Separate test data from production data

### 3. Error Testing
- **Exception Scenarios**: Test error conditions thoroughly
- **Edge Cases**: Boundary value testing
- **Resource Constraints**: Memory and timeout limitations

### 4. Performance Testing
- **Concurrent Operations**: Multi-threading safety
- **Memory Management**: Resource leak detection
- **Timeout Handling**: Operation time limits

## 🚨 Troubleshooting

### Common Issues

#### 1. Missing Dependencies
```
Error: Could not load file or assembly 'RefactorIQ.Core'
```
**Solution**: Ensure RefactorIQ projects are built first

#### 2. File System Tests
```
Error: Access to the path is denied
```
**Solution**: Run tests with appropriate permissions or use temporary directories

#### 3. Configuration Validation
```
Error: Required property 'Git' is null
```
**Solution**: Use `TestDataBuilder.CreateValidConfiguration()` for test data

### Test Environment Setup

1. **Build Dependencies**:
   ```bash
   dotnet build ../MarketAlly.AIPlugin.Learning
   ```

2. **Restore Packages**:
   ```bash
   dotnet restore
   ```

3. **Verify Test Discovery**:
   ```bash
   dotnet test --list-tests
   ```

## 📈 Continuous Integration

### GitHub Actions Example

```yaml

## 📝 Contributing to Tests

### Adding New Tests

1. **Choose Appropriate Category**: Service, Configuration, Integration
2. **Follow Naming Conventions**: `MethodName_Scenario_ExpectedResult`
3. **Use Test Builders**: Leverage `TestDataBuilder` for consistent data
