A mocking library for C# Kiota clients using a fluent library. This library is heavily inspired by the mockhttp library by richardszalay
The simple example provided by Microsoft is shown below with some sections removed for brevity
public class PostsRequestsTests
{
private static readonly List<Post> postsMock =
[ new Post { Id = 1, Title = "Post Title #1", Body = "Posts Body #1" } ];
// Basic test for GET /posts
[Fact]
public async Task All_Posts()
{
// Arrange
var adapter = Substitute.For<IRequestAdapter>();
var postsClient = new PostsClient(adapter);
// Return the mocked list of posts
adapter.SendCollectionAsync(
Arg.Any<RequestInformation>(),
Arg.Any<ParsableFactory<Post>>(),
Arg.Any<Dictionary<string, ParsableFactory<IParsable>>>(),
Arg.Any<CancellationToken>())
.ReturnsForAnyArgs(postsMock);
// Act
var posts = await postsClient.Posts.GetAsync();
// Assert
Assert.NotNull(posts);
Assert.Equal(postsMock.Count, posts.Count);
}
}As you can see, the simplest mock for IRequestAdapter requires a lot of configuration, most of which is of low importance in a unit test.
If you have a test which would call a Kiota client multiple times with different methods, each of these substitution statements would need to be more complex.
With more complex tests, the intention of each test gets harder to understand as you have to understand the meaning of any boilerplate code.
