🔧 Test Configuration

Test Dependencies

<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

[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

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

3. Concurrent Operation Testing

[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:

   dotnet build ../MarketAlly.AIPlugin.Learning
   

2. Restore Packages:

   dotnet restore
   

3. Verify Test Discovery:

   dotnet test --list-tests
