Can I use Moq to verify that a mocked method was called with specific values in a complex parameter?

Yes, you can use Moq to verify that a mocked method was called with specific values in a complex parameter. Moq provides the It class, which allows you to specify complex argument matching expressions for method calls.

Assuming you have a complex parameter in your mocked method, you can use the It.Is<T> method to define a predicate that checks whether the parameter matches specific values or conditions.

Here's an example of how to verify that a mocked method was called with a complex parameter containing specific values:

using System; using Moq; public class ComplexParameter { public int Value1 { get; set; } public string Value2 { get; set; } } public interface IService { void ProcessComplexParameter(ComplexParameter parameter); } public class MyService : IService { public void ProcessComplexParameter(ComplexParameter parameter) { // Do something with the parameter } } public class Program { public static void Main() { // Create a mock of the IService interface Mock<IService> mockService = new Mock<IService>(); // Create an instance of the class that uses the mocked service MyServiceConsumer serviceConsumer = new MyServiceConsumer(mockService.Object); // Create a complex parameter with specific values ComplexParameter parameterToMatch = new ComplexParameter { Value1 = 42, Value2 = "Test" }; // Call the method that uses the mocked service with the complex parameter serviceConsumer.UseServiceWithComplexParameter(parameterToMatch); // Verify that the ProcessComplexParameter method was called with the specified parameter mockService.Verify(s => s.ProcessComplexParameter(It.Is<ComplexParameter>(p => p.Value1 == parameterToMatch.Value1 && p.Value2 == parameterToMatch.Value2)), Times.Once); } } public class MyServiceConsumer { private readonly IService _service; public MyServiceConsumer(IService service) { _service = service; } public void UseServiceWithComplexParameter(ComplexParameter parameter) { _service.ProcessComplexParameter(parameter); } }

In this example, we have a service (IService) with a method ProcessComplexParameter that takes a complex parameter ComplexParameter. We want to verify that the method was called with a specific ComplexParameter instance containing particular values.

In the Program class, we create a mock of IService and set it up to be used by MyServiceConsumer. We then create a complex parameter parameterToMatch with specific values and call the method in MyServiceConsumer that uses the mocked service with this parameter.

Finally, we use mockService.Verify with It.Is<ComplexParameter> to verify that the ProcessComplexParameter method was called with the specific ComplexParameter instance that matches the values in parameterToMatch.

By using It.Is, you can create complex argument matching expressions and verify that your mocked method was called with the expected complex parameter.

Examples

  1. "Moq verify method called with specific parameter values"

    Code:

    // Assuming IMyInterface is the mocked interface and DoSomething is the method var mock = new Mock<IMyInterface>(); // Arrange var expectedParameter = new MyComplexType { Property1 = "Value1", Property2 = "Value2" }; // Act mock.Object.DoSomething(expectedParameter); // Assert mock.Verify(x => x.DoSomething(It.Is<MyComplexType>(param => param.Property1 == "Value1" && param.Property2 == "Value2")), Times.Once);

    Description: Use It.Is to specify specific values for properties of a complex parameter when verifying that a method was called.

  2. "Moq verify method called with matching complex parameter"

    Code:

    // Assuming IMyInterface is the mocked interface and ProcessData is the method var mock = new Mock<IMyInterface>(); // Arrange var expectedData = new DataObject { Id = 1, Name = "TestObject" }; // Act mock.Object.ProcessData(expectedData); // Assert mock.Verify(x => x.ProcessData(It.Is<DataObject>(data => data.Id == 1 && data.Name == "TestObject")), Times.Once);

    Description: Verify that a method was called with a specific complex parameter using It.Is.
