How do I test MVC controllers in my application?

To test MVC controllers, you can use unit testing frameworks like NUnit or xUnit. You can mock dependencies and verify the behavior of your controllers.

What tools do you recommend for mocking dependencies?

I recommend using Moq or NSubstitute for mocking dependencies in your tests. They are both popular and easy to use.

Can you show me a simple example of a test case?

Sure! Here's a simple example using xUnit and Moq:

[Fact]
public void Get_ReturnsViewResult_WithCorrectModel()
{
    // Arrange
    var mockRepo = new Mock<IRepository>();
    var controller = new MyController(mockRepo.Object);

    // Act
    var result = controller.Index();

    // Assert
    var viewResult = Assert.IsType<ViewResult>(result);
    Assert.IsAssignableFrom<MyModel>(viewResult.Model);
}
