Testing

Adding a category to a test for filtering purposes. The source code sample demonstrates how to use the Trait attribute in C# with xUnit to categorize a test as an "IntegrationTest." This categorization helps in filtering and organizing tests based on their nature or purpose.

By using the Trait attribute with key-value pairs like "Category" and "IntegrationTests," tests can be grouped and executed selectively during testing workflows.

Sample code snippet:

[Fact, Trait("Category", "IntegrationTests")]
public async Task AcquireToken_GetToken_TokenNotNullOrEmpty()
{
   // test implementation
}

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());
}
