Unit Testing Exceptions in Async Methods

Unit testing throwing exceptions in asynchronous methods involves verifying that an async method correctly throws expected exceptions under specific conditions. This ensures robust error handling and code reliability in asynchronous programming.

Here's a sample C# code snippet using xUnit for unit testing async methods that throw exceptions:

public async Task TestAsyncMethod()
{
    // Arrange

    // Act
    async Task Act() => await _service.AsyncMethod();

    // Assert
    await Assert.ThrowsAsync<Exception>(() => Act());
}
