How can I test asynchronous methods in ASP.NET?

How can I test asynchronous methods in ASP.NET?

You can use the built-in testing framework like xUnit or NUnit along with Moq for mocking dependencies.

Can you show me an example of testing an async method?

Sure! Here's a simple example using xUnit:

[Fact]
public async Task TestAsyncMethod()
{
    // Arrange
    var service = new MyService();

    // Act
    var result = await service.MyAsyncMethod();

    // Assert
    Assert.NotNull(result);
}

What about handling exceptions in async tests?

You can use Assert.ThrowsAsync to verify that an exception is thrown during the execution of an async method.

Are there any best practices for async testing?

Yes, always ensure your tests are isolated, use proper mocking, and avoid using Task.Wait() to prevent deadlocks.
