+ + var service = new DownloadManager(); + + var exception = await Assert.ThrowsAsync( + () => service.DownloadFileAsync("https://example.com/file.zip")); + + Assert.IsNotNull(exception); +} +``` + +## Advanced Scenarios + +### Callback Execution + +Execute custom logic when mocks are called: + +```csharp +[Test] +public void Mock_With_Callbacks() +{ + var loggedMessages = new List(); + + using var mock = Mock.Setup(() => Logger.Log(It.IsAny())) + .Callback(message => + { + loggedMessages.Add($"Captured: {message}"); + Console.WriteLine($"Mock captured: {message}"); + }); + + var service = new BusinessService();

+ Assert.AreEqual("User", SecurityService.ValidateUser("user_jane").Role); + Assert.IsFalse(SecurityService.ValidateUser("guest").IsValid); +} +``` + +## Best Practices + +### 1. Scope Mocks Appropriately + +```csharp +[Test] +public void Good_Mock_Scoping() +{ + // ✅ Good: Scope mocks to specific test needs + using var timeMock = Mock.Setup(() => DateTime.Now) + .Returns(new DateTime(2024, 1, 1)); + + using var fileMock = Mock.Setup(() => File.Exists("config.json")) + .Returns(true); + + // Test logic here +} + +[Test] +public void Bad_Mock_Scoping() +{ + // ❌ Bad: Don't create mocks you don't use in the test + using var unnecessaryMock = Mock.Setup(() => Console.WriteLine(It.IsAny())); + + // Test that doesn't use Console.WriteLine +} +``` + +### 2. Use Meaningful Return Values + +```csharp +[Test] +public void Meaningful_Return_Values() +{ + // ✅ Good: Return values that make sense for the test + using var mock = Mock.Setup(() => UserRepository.GetUserById(123)) + .Returns(new User + { + Id = 123, + Name = "Test User", + Email = "test@example.com", + IsActive = true + }); + + // ❌ Bad: Return meaningless default values + using var badMock = Mock.Setup(() => UserRepository.GetUserById(456)) + .Returns(new User()); // Empty object with no meaningful data +} +``` + +### 3. Group Related Mocks + +```csharp +[Test] +public void Group_Related_Mocks() +{ + // ✅ Good: Group mocks that work together + using var existsMock = Mock.Setup(() => File.Exists("database.config")) + .Returns(true); + using var readMock = Mock.Setup(() => File.ReadAllText("database.config")) + .Returns("connection_string=test_db"); + using var writeMock = Mock.Setup(() => File.WriteAllText(It.IsAny(), It.IsAny())); + + // Test configuration management + var configManager = new ConfigurationManager(); + configManager.UpdateConfiguration("new_setting", "value"); +} +``` + +### 4. Verify Mock Usage When Needed + +```csharp +[Test] +public void Verify_Mock_Usage() +{ + var callCount = 0; + + using var mock = Mock.Setup(() => AuditLogger.LogAction(It.IsAny())) + .Callback(action => callCount++); + + var service = new CriticalService(); + service.PerformCriticalOperation(); + + // Verify the audit log was called + Assert.AreEqual(1, callCount, "Audit logging should be called exactly once"); +} +``` + +## Common Patterns + +### Configuration Testing + +```csharp +[Test] +public void Configuration_Pattern() +{ + var testConfig = new Dictionary + { + ["DatabaseConnection"] = "test_connection", + ["ApiKey"] = "test_key_12345", + ["EnableFeatureX"] = "true" + }; + + using var mock = Mock.Setup(() => + ConfigurationManager.AppSettings[It.IsAny()]) + .Returns(key => testConfig.GetValueOrDefault(key)); + + var service = new ConfigurableService(); + service.Initialize(); + + Assert.IsTrue(service.IsFeatureXEnabled); + Assert.AreEqual("test_connection", service.DatabaseConnection); +} +``` + +### Time-Dependent Testing + +```csharp +[Test] +public void Time_Dependent_Pattern() +{ + var testDate = new DateTime(2024, 6, 15, 14, 30, 0); // Saturday afternoon + + using var mock = Mock.Setup(() => DateTime.Now) + .Returns(testDate); + + var scheduler = new TaskScheduler(); + var nextRun = scheduler.CalculateNextBusinessDay(); + + // Should be Monday since Saturday -> next business day is Monday + Assert.AreEqual(DayOfWeek.Monday, nextRun.DayOfWeek); + Assert.AreEqual(new DateTime(2024, 6, 17), nextRun.Date); +} +``` + +### External Dependency Testing + +```csharp +[Test] +public void External_Dependency_Pattern() +{ + // Mock external web service + using var webMock = Mock.Setup(() => + WebClient.DownloadString("https://api.weather.com/current")) + .Returns("{\"temperature\": 22, \"condition\": \"sunny\"}"); + + // Mock file system for caching + using var fileMock = Mock.Setup(() => + File.WriteAllText(It.IsAny(), It.IsAny())); + + var weatherService = new WeatherService(); + var weather = weatherService.GetCurrentWeather(); + + Assert.AreEqual(22, weather.Temperature); + Assert.AreEqual("sunny", weather.Condition); +} +``` + +## Troubleshooting + +### Common Issues and Solutions + +#### Issue: Mock Not Triggering + +**Problem**: Your mock setup looks correct, but the original method is still being called. + +```csharp +// ❌ This might not work as expected +Mock.Setup(() => SomeClass.Method()).Returns("mocked"); +var result = SomeClass.Method(); // Still calls original! +``` + +**Solution**: Ensure you're calling the exact same method signature. + +```csharp +// ✅ Make sure parameter types match exactly +Mock.Setup(() => SomeClass.Method(It.IsAny())).Returns("mocked"); +var result = SomeClass.Method("any_parameter"); // Now mocked! +``` + +#### Issue: Parameter Matching Not Working + +**Problem**: Your parameter matcher seems too restrictive. + +```csharp +// ❌ Too specific +Mock.Setup(() => Validator.Validate("exact_string")).Returns(true); +var result = Validator.Validate("different_string"); // Not mocked! +``` + +**Solution**: Use appropriate parameter matchers. + +```csharp +// ✅ Use IsAny for flexible matching +Mock.Setup(() => Validator.Validate(It.IsAny())).Returns(true); + +// ✅ Or use Is with conditions +Mock.Setup(() => Validator.Validate(It.Is(s => s.Length > 0))).Returns(true); +``` + +#### Issue: Async Mocks Not Working + +**Problem**: Async methods aren't being mocked properly. + +```csharp +// ❌ Wrong return type +Mock.Setup(() => Service.GetDataAsync()).Returns("data"); // Won't compile! +``` + +**Solution**: Return the correct Task type. + +```csharp +// ✅ Return Task with proper value +Mock.Setup(() => Service.GetDataAsync()).Returns(Task.FromResult("data")); + +// ✅ Or use async lambda +Mock.Setup(() => Service.GetDataAsync()).Returns(async () => +{ + await Task.Delay(10); + return "data"; +}); +``` + +#### Issue: Mocks Interfering Between Tests + +**Problem**: Mocks from one test affecting another. + +**Solution**: Always use `using` statements with Sequential API to ensure proper cleanup. + +```csharp +[Test] +public void Test_With_Proper_Cleanup() +{ + using var mock = Mock.Setup(() => DateTime.Now) + .Returns(new DateTime(2024, 1, 1)); + + // Test logic here +} // Mock automatically disposed and cleaned up +``` + +### Getting Help + +When you encounter issues: + +1. **Check the Documentation**: Review this guide and the [API reference](../api/index.md) +2. **Search Issues**: Check [GitHub Issues](https://github.com/SvetlovA/static-mock/issues) for similar problems +3. **Create Minimal Repro**: Prepare a minimal code example that demonstrates the issue +4. **Ask for Help**: Create a new issue with details about your environment and problem + +### Performance Considerations + +- **Mock Setup Cost**: Creating mocks has a small one-time cost (~1-2ms per mock) +- **Runtime Overhead**: Method interception is very fast (<0.1ms per call) +- **Memory Usage**: Minimal impact, temporary IL modifications only +- **Cleanup**: Always dispose Sequential mocks to free resources promptly + +## Next Steps + +Now that you understand the basics of SMock, explore these resources: + +- **[API Reference](../api/index.md)** - Complete API documentation +- **[GitHub Repository](https://github.com/SvetlovA/static-mock)** - Source code, examples, and community +- **[NuGet Package](https://www.nuget.org/packages/SMock)** - Latest releases and version history + +Happy testing with SMock! 🚀 \ No newline at end of file diff --git a/docfx_project/articles/intro.md b/docfx_project/articles/intro.md deleted file mode 100644 index c1b96c8..0000000 --- a/docfx_project/articles/intro.md +++ /dev/null @@ -1,104 +0,0 @@ -# SMock -SMock is opensource lib for mocking static and instance methods and properties. -# Installation -Download and install the package from [NuGet](https://www.nuget.org/packages/SMock/) or [GitHub](https://github.com/SvetlovA/static-mock/pkgs/nuget/SMock) -# Getting Started -## Hook Manager Types -SMock is based on [MonoMod](https://github.com/MonoMod/MonoMod) library that produce hook functionality -## Code Examples -Setup is possible in two ways **Hierarchical** and **Sequential** -### Returns (Hierarchical) -```cs -Mock.Setup(context => StaticClass.MethodToMock(context.It.IsAny()), () => -{ - var actualResult = StaticClass.MethodToMock(1);

Exact parameter matching (fastest) +Mock.Setup(() => MyClass.Method("exact_value")).Returns("result"); + +// 2.

+ } +} +``` + +## Frequently Asked Questions + +### Q: Can SMock mock sealed classes? +**A:** SMock mocks methods, not classes. It can mock static methods on sealed classes, but cannot mock instance methods on sealed classes that aren't virtual. + +```csharp +// ✅ This works - static method on sealed class +using var mock = Mock.Setup(() => File.ReadAllText(It.IsAny())) + .Returns("mocked content"); + +// ❌ This won't work - instance method on sealed class +// var sealedInstance = new SealedClass(); +// Mock.Setup(() => sealedInstance.NonVirtualMethod()).Returns("value"); +``` + +### Q: How does SMock compare performance-wise to other mocking frameworks? +**A:** SMock has minimal runtime overhead for method interception (<0.1ms per call), but higher setup cost (~1-2ms) due to IL modification. For most testing scenarios, this is negligible. + +### Q: Can I use SMock in production code? +**A:** No, SMock is designed exclusively for testing. It modifies runtime behavior and should never be used in production builds. + +### Q: Does SMock work with .NET Native/AOT? +**A:** SMock requires runtime IL modification capabilities that may not be available in AOT-compiled applications. It's designed for traditional .NET runtimes. + +### Q: Can I mock methods from third-party libraries? +**A:** Yes, SMock can mock any static method from any assembly, including third-party libraries. + +```csharp +// Works with third-party libraries +using var mock = Mock.Setup(() => JsonConvert.SerializeObject(It.IsAny())) + .Returns("{\"mocked\": true}"); +``` + +### Q: How do I verify that a mocked method was called? +**A:** Use callbacks to track method calls: + +```csharp +[Test] +public void Verify_Method_Called() +{ + var wasCalled = false; + + using var mock = Mock.Setup(() => Logger.Log(It.IsAny())) + .Callback(msg => wasCalled = true); + + // Your code that should call Logger.Log + MyService.DoSomething(); + + Assert.IsTrue(wasCalled, "Logger.Log should have been called"); +} +``` + +### Q: Can I mock generic methods? +**A:** Yes, but you need to specify the generic type parameters: + +```csharp +// ✅ Specify the generic type +using var mock = Mock.Setup(() => JsonSerializer.Deserialize(It.IsAny())) + .Returns(new MyClass()); + +// ❌ Don't use open generic types +// Mock.Setup(() => JsonSerializer.Deserialize(It.IsAny())) +``` + +## Getting Help + +### Self-Diagnosis Checklist + +Before seeking help, run through this checklist: + +- [ ] SMock package is properly installed and up-to-date +- [ ] Mock setup syntax is correct (parameter matching, return types) +- [ ] Using statements or proper disposal for Sequential API +- [ ] No conflicting mocks for the same method +- [ ] Test framework compatibility verified +- [ ] Environment supports runtime IL modification + +### Reporting Issues + +When reporting issues, include: + +1. **SMock Version**: `dotnet list package SMock` +2. **Environment**: .NET version, OS, architecture +3. **Minimal Reproduction**: Simplest code that demonstrates the issue +4. **Expected vs Actual**: What you expected vs what happened +5. **Error Messages**: Full exception messages and stack traces +6. **Test Framework**: NUnit, xUnit, MSTest version + +### Community Resources + +- **GitHub Issues**: [Report bugs and feature requests](https://github.com/SvetlovA/static-mock/issues) +- **GitHub Discussions**: [Ask questions and share solutions](https://github.com/SvetlovA/static-mock/discussions) +- **Documentation**: [Complete API reference](../api/index.md) +- **Examples**: [Real-world usage patterns](real-world-examples.md) + +### Professional Support + +For enterprise users requiring professional support: +- Priority issue resolution +- Custom integration assistance +- Performance optimization consulting +- Training and onboarding + +Contact: [GitHub Sponsors](https://github.com/sponsors/SvetlovA) for enterprise support options. + +This troubleshooting guide should help you resolve most SMock-related issues.

Mock Lifecycle Management - -**Optimize mock creation and disposal**: - -```csharp -// ❌ Inefficient: Creating mocks unnecessarily -[Test] -public void Inefficient_Mock_Usage() -{ - using var mock1 = Mock.Setup(() => Service1.Method()).Returns("value1"); - using var mock2 = Mock.Setup(() => Service2.Method()).Returns("value2"); - using var mock3 = Mock.Setup(() => Service3.Method()).Returns("value3"); - - // Only Service1.Method() is actually called - var result = Service1.Method(); - Assert.AreEqual("value1", result); -} - -// ✅ Efficient: Only mock what you need -[Test] -public void Efficient_Mock_Usage() -{ - using var mock = Mock.Setup(() => Service1.Method()).Returns("value1"); - - var result = Service1.Method(); - Assert.AreEqual("value1", result); -} -``` - -### 2. Parameter Matching Optimization - -**Choose the most efficient parameter matching strategy**: - -```csharp -// Performance ranking (fastest to slowest): - -// 1. Exact parameter matching (fastest) -Mock.Setup(() => MyClass.Method("exact_value")).Returns("result"); - -// 2. It.IsAny() matching -Mock.Setup(() => MyClass.Method(It.IsAny())).Returns("result"); - -// 3. Simple It.Is() conditions -Mock.Setup(() => MyClass.Method(It.Is(s => s != null))).Returns("result"); - -// 4. Complex It.Is() conditions (slowest) -Mock.Setup(() => MyClass.Method(It.Is(s => - s != null && s.Length > 5 && s.Contains("test")))).Returns("result"); -``` - -### 3. Batch Mock Setup - -**Group related mocks to minimize setup overhead**: - -```csharp -public class OptimizedTestBase -{ - protected static readonly Dictionary> MockTemplates = - new Dictionary> - { - ["datetime_fixed"] = () => Mock.Setup(() => DateTime.Now) - .Returns(new DateTime(2024, 1, 1)), - - ["file_exists_true"] = () => Mock.Setup(() => File.Exists(It.IsAny())) - .Returns(true), - - ["environment_test"] = () => Mock.Setup(() => Environment.MachineName) - .Returns("TEST_MACHINE") - }; - - protected IDisposable CreateMock(string template) => MockTemplates[template](); -} - -[TestFixture] -public class OptimizedTests : OptimizedTestBase -{ - [Test] - public void Test_With_Prebuilt_Mocks() - { - using var dateMock = CreateMock("datetime_fixed"); - using var envMock = CreateMock("environment_test"); - - // Test logic with optimized mock setup - var service = new TimeAwareService(); - var result = service.GetMachineTimeStamp(); - - Assert.IsNotNull(result); - } -} -``` - -### 4. Conditional Mock Activation - -**Use lazy initialization for expensive mocks**: - -```csharp -[Test] -public void Lazy_Mock_Activation() -{ - Lazy expensiveMock = new(() => - Mock.Setup(() => ExpensiveExternalService.ComputeComplexResult(It.IsAny())) - .Returns("precomputed_result")); - - var service = new OptimizedService(); - - // Mock only created if external service is actually needed - var result = service.ProcessData("simple_data"); // No external service call - Assert.IsNotNull(result); - - if (service.RequiresExternalComputation("complex_data")) - { - using var mock = expensiveMock.Value; - var complexResult = service.ProcessData("complex_data"); - Assert.IsNotNull(complexResult); - } -} -``` - -### 5. Memory-Efficient Mock Patterns - -**Optimize memory usage with smart mock disposal**: - -```csharp -public class MemoryEfficientMockManager : IDisposable -{ - private readonly List _activeMocks = new(); - private readonly ConcurrentDictionary _mockCache = new(); - - public IDisposable GetOrCreateMock(string key, Func factory) + public void MultipleMocksSetup() { - if (_mockCache.TryGetValue(key, out var weakRef) && - weakRef.IsAlive && weakRef.Target is IDisposable existingMock) - { - return existingMock;

- var result = service.GetFileTimestamp("test.txt"); - - Assert.IsNotNull(result); -} // All mocks disposed automatically -``` - -## Memory Management - -### Memory Usage Patterns - -SMock's memory usage follows predictable patterns: - -```csharp -[Test] -public void Analyze_Memory_Patterns() -{ - var initialMemory = GC.GetTotalMemory(true); - - // Create multiple mocks and measure memory growth - var mocks = new List(); - - for (int i = 0; i < 100; i++) - { - var mock = Mock.Setup(() => TestClass.Method(i.ToString())) - .Returns($"result_{i}"); - mocks.Add(mock); - - if (i % 10 == 0) - { - var currentMemory = GC.GetTotalMemory(false); - var memoryUsed = currentMemory - initialMemory; - Console.WriteLine($"Mocks: {i + 1}, Memory: {memoryUsed:N0} bytes, Per mock: {memoryUsed / (i + 1):N0} bytes"); - } - } - - // Cleanup and measure memory release - mocks.ForEach(m => m.Dispose()); - var finalMemory = GC.GetTotalMemory(true); - - Console.WriteLine($"Initial: {initialMemory:N0} bytes"); - Console.WriteLine($"Final: {finalMemory:N0} bytes"); - Console.WriteLine($"Memory retained: {finalMemory - initialMemory:N0} bytes"); - - // Most memory should be released - Assert.Less(finalMemory - initialMemory, 50_000, "Memory retention should be minimal"); -} -``` - -### Garbage Collection Impact - -```csharp -[Test] -public void Measure_GC_Impact() -{ - var gen0Before = GC.CollectionCount(0); - var gen1Before = GC.CollectionCount(1); - var gen2Before = GC.CollectionCount(2); - - // Create and dispose many mocks - for (int i = 0; i < 1000; i++) - { - using var mock = Mock.Setup(() => TestClass.Method(It.IsAny())) - .Returns("result"); - - var _ = TestClass.Method($"test_{i}"); - } - - var gen0After = GC.CollectionCount(0); - var gen1After = GC.CollectionCount(1); - var gen2After = GC.CollectionCount(2); - - Console.WriteLine($"Gen 0 collections: {gen0After - gen0Before}"); - Console.WriteLine($"Gen 1 collections: {gen1After - gen1Before}"); - Console.WriteLine($"Gen 2 collections: {gen2After - gen2Before}"); - - // SMock should not cause excessive GC pressure - Assert.Less(gen2After - gen2Before, 2, "Should not trigger many Gen 2 collections");

- Console.WriteLine($"Average test time: {averageTime:F2}ms"); - Console.WriteLine($"Max test time: {maxTime:F2}ms"); - Console.WriteLine($"Tests per second: {testCount / overallStart.Elapsed.TotalSeconds:F1}"); - - // Performance thresholds for scalability - Assert.Less(averageTime, 50, "Average test time should be under 50ms"); - Assert.Less(maxTime, 200, "No test should take more than 200ms"); - } - - private void ExecuteIndividualTest(int testIndex) - { - var stopwatch = Stopwatch.StartNew();

- - stopwatch.Stop(); - PerformanceMetrics[$"test_{testIndex}"] = stopwatch.Elapsed; - } -} -``` - -### Concurrent Test Execution - -SMock is designed to handle concurrent test execution: - -```csharp -[Test] -public void Concurrent_Mock_Usage() -{ - var concurrentTests = 50;

Minimize Parameter Matching Overhead + +**Problem**: `It.IsAny()` adds 6-7x overhead compared to exact value matching + +```csharp +// ❌ Slower - Dynamic parameter matching (8.5ms) +Mock.Setup(context => MyClass.Method(context.It.IsAny())) + .Returns(42); + +// ✅ Faster - Exact parameter matching (1.3ms) +Mock.Setup(() => MyClass.Method("specific-value")) + .Returns(42); +``` + +**When to use each**: +- Use exact matching for known test values +- Use `IsAny()` only when parameter values vary significantly +- Consider conditional matching `It.Is(predicate)` for complex validation + +### 2. Prefer Static Method Mocking + +**Modern .NET Performance Comparison**: +- Static method setup: 600-730 μs +- Instance method setup: 1,050 μs (40% slower) + +```csharp +// ✅ Preferred - Static method mocking +Mock.Setup(() => DateTime.Now) + .Returns(new DateTime(2024, 1, 1)); + +// ❌ Slower - Instance method mocking +Mock.Setup(() => myInstance.GetCurrentTime()) + .Returns(new DateTime(2024, 1, 1)); +``` + +### 3. Framework Selection Strategy + +**Choose Modern .NET (.NET 8+) for**: +- New projects requiring optimal memory usage +- High-frequency test execution +- CI/CD pipelines with memory constraints + +**Stick with .NET Framework for**: +- Legacy codebases where parameter matching is heavily used +- Projects with existing .NET Framework dependencies +- When `IsAny()` operations dominate your test scenarios + +### 4. Efficient Mock Management + +#### Group Mock Setup +```csharp +// ✅ Efficient - Setup multiple mocks together +using var mock1 = Mock.Setup(() => DateTime.Now).Returns(fixedDate); +using var mock2 = Mock.Setup(() => Environment.MachineName).Returns("TEST"); +using var mock3 = Mock.Setup(() => File.Exists(It.IsAny())).Returns(true); + +// Execute all operations +``` + +#### Avoid Excessive Mock Creation +```csharp +// ❌ Inefficient - Creating mocks in loops +for (int i = 0; i < 100; i++) +{ + using var mock = Mock.Setup(() => Method()).Returns(i); + Method(); // Each iteration pays setup cost +} + +// ✅ Efficient - Single mock with callback +var results = new Queue(Enumerable.Range(0, 100)); +using var mock = Mock.Setup(() => Method()) + .Returns(() => results.Dequeue()); + +for (int i = 0; i < 100; i++) +{ + Method(); // Only execution cost +} +``` + +### 5. Callback Optimization + +Simple callbacks perform better than complex ones: + +```csharp +// ✅ Fast - Simple callback (950 μs) +Mock.Setup(context => Method(context.It.IsAny())) + .Callback(_ => { /* minimal work */ }); + +// ❌ Slower - Complex callback (2.6ms) +Mock.Setup(context => Method(context.It.IsAny())) + .Callback(x => { + // Complex computation + var result = ExpensiveOperation(x); + ProcessResult(result); + }); +``` + +## Memory Management + +SMock automatically manages memory for mock hooks and IL modifications. However, you can optimize memory usage: + +### Disposal Patterns + +```csharp +// ✅ Automatic disposal with using +using var mock = Mock.Setup(() => Method()).Returns(42); +// Hook automatically removed at end of scope + +// ❌ Manual disposal required +var mock = Mock.Setup(() => Method()).Returns(42); +// ... test code ... +mock.Dispose(); // Must explicitly dispose +``` + +### Memory Pressure Monitoring + +For memory-intensive testing scenarios: + +```csharp +// Monitor memory usage during extensive mocking +var initialMemory = GC.GetTotalMemory(false); + +// ... extensive mock operations ... + +var finalMemory = GC.GetTotalMemory(true); // Force GC +var memoryUsed = finalMemory - initialMemory; + +Assert.That(memoryUsed, Is.LessThan(expectedThreshold)); +``` + +## Performance Monitoring + +### Benchmark Integration + +Add performance assertions to your test suite: + +```csharp +[Test] +public void MockSetup_ShouldCompleteWithinTimeLimit() +{ + var stopwatch = Stopwatch.StartNew(); + + using var mock = Mock.Setup(() => ExpensiveMethod()) + .Returns(42); + + stopwatch.Stop(); + + // Assert reasonable setup time (adjust based on your requirements) + Assert.That(stopwatch.ElapsedMilliseconds, Is.LessThan(10)); +} +``` + +### Profiling Integration + +For continuous monitoring, integrate with APM tools: + +```csharp +// Example with custom timing wrapper +public class TimedMockSetup : IDisposable where T : IDisposable +{ + private readonly T _mock; + private readonly IMetrics _metrics; + private readonly string _operationName; + private readonly Stopwatch _stopwatch; + + public TimedMockSetup(T mock, IMetrics metrics, string operationName) + { + _mock = mock; + _metrics = metrics; + _operationName = operationName; + _stopwatch = Stopwatch.StartNew(); + } + + public void Dispose() + { + _stopwatch.Stop(); + _metrics.RecordValue($"mock_setup_{_operationName}", _stopwatch.ElapsedMilliseconds); + _mock.Dispose(); + } + + public static implicit operator T(TimedMockSetup setup) => setup._mock; +} ``` \ No newline at end of file diff --git a/src/StaticMock.Tests.Benchmark/ComprehensiveBenchmarks.cs b/src/StaticMock.Tests.Benchmark/ComprehensiveBenchmarks.cs index 411797a..be561be 100644 --- a/src/StaticMock.Tests.Benchmark/ComprehensiveBenchmarks.cs +++ b/src/StaticMock.Tests.Benchmark/ComprehensiveBenchmarks.cs @@ -4,7 +4,6 @@ namespace StaticMock.Tests.Benchmark;
