Create a wrapper around HttpClient, inject it in your SUT using singleton scope, then you can use Moq to mock the IHttpClient to always return the response you want when you execute SendAsync. If you replace ItExpr. var response = await ProcessRequestAsync(func); // response = await ProcessRequestAsync(func); In this case func returns the same request every single time. Voilà! That’s how to write tests with HttpClient and Moq. Protected() method. Here's my analysis of the situation: The class MultipartContent basically has a collection of child HttpContent objects (ByteArrayContent is inheriting from HttpContent). I would suggest a different approach. I created a DefaultHttpContext, set the headers there, I just discovered that with HttpRequestMessage class, you can easily add headers for testing your WebAPI controllers without having to create any fake HttpContext. Here's an example of what your Fake Factory could look like: I have the following Method which returns HttpResponseMessage public async Task<HttpResponseMessage> PatchStatus(string transactionId, JsonPatchDocument<BspStatusDetails> patchDoc) Please correct me if I'm wrong. NET, spinning up a new HttpClient is at least a monthly pleasure. 5. CreateResponse is an extension method that, internally, makes use of the request's associated HttpConfiguration. I start learn Moq and I have this problem. My first attempt was: var mock = new Mock<WebRequest>(); mock. In this case all you have to do is to extract Task. So even without calling Setup, Moq has already stubbed the methods for IPrinter so you can just call Verify. The method that we’ll need to setup is SendAsync(), which is ultimately what all HTTP requests are made through. Why does my test fails, if I run it besides others (whole test class) but always pass if I run it individually. Request = new HttpRequestMessage(); controller. Hot Network Questions HttpRequestMessage response = // Obtain the message somewhere, like HttpClient. HttpContextFactory. unconstrained mocking libraries in the art of unit testing. This gives you some additional methods on the Moq, where you can access the protected members using their names. Moq setup throw exception. Protected. Hot Network Questions What is the special significance of laying the lost& found sheep on the shepherd ' s shoulders? To learn more about using Moq to create/configure/use mock objects check out my Mocking in . It's an ASP. Expected. Many time we call external rest API’s from our backend code and we want to write unit test for such code so that we can test our code with the Here is an example of how to write a Unit Test using moq to check that an HttpModule is working as expected: Unit Test for HttpModule using Moq to wrap HttpRequest. That is the only requirements that needs to be setup before using it in your test. Even, we can setup the fake HttpMessageHandler passing an Uri with a method ForUri(), for example. In my specific case I had to mock an HttpResponseMessage setting up the status code to return Ok, but how to do it if that property is not virtual?. Since you use Capture directly in the parameter list, it is far less prone to issues when refactoring a method's parameter list, and therefore makes tests less brittle. Please try to avoid having parameters like this: Object requestBody, prefer two generic parameters instead; Task<(TResponse, HttpStatusCode)> SendPostAsync<TRequest, TResponse>( LoggingContext loggingContext, string path, CancellationToken ct, TRequest requestBody, string spanTitle, Let me know if I am wrong, it's the first time I use moq object. Mock. If you are testing some I want to write Unit test cases for following code HomeController. Note that this You created a Mock<IResponseMessage>, which uses MockBehavior. By using the TResult value overload of Returns, you are choosing to always return the exact same HttpResponseMessage instance for all handler. using Moq I have an asp . Object); controller. However, as a good practice, I always set it up because we may need to enforce the parameters to the method or How to mock HttpRequestMessage with Moq. In this article, we shall see how to Unit Test and Mock HttpRequest in ASP. 2. Hot Network Questions Why does a = a * (x + i) / i; and a *= (x + i) / i; return two different results? Not sure if previous version didn't allow for that, but if you have different HTTP calls within the same method, you can Moq each of them by specifying the HttpRequestMessage, similar to what you did. 325 1 1 I am using Moq in my XUnit test. 0 How to mock a post request? 13 Mock ControllerBase Request using Moq.
