Is there a generic term for these trajectories? This will add quite a few extra scenarios where things can go wrong, the most commonly be timeouts and expiration of tokens. Not the answer you're looking for? In case of unit testing you are not relying on your DI. According to my understanding in your provided sample you are making asserting only against the result. Have a question about this project? Going further and checking HttpMessageInvoker, you can see that it is not an abstract class nor it implements any interface other than IDisposable which is not much helpful for us in this case since we need to mock behaviors id GetStringAsync method which does not come from IDisposable. Why did DOS-based Windows require HIMEM.SYS to boot? Can you still use Commanders Strike if the only attack available to forego is an attack against an ally? If I configure Policy.Handle().Retry(3), it would be nice to check it really works, right? If you want to test the Polly policy configured on IHttpClientService within your app, via an end-to-end integration test of your app orchestrated by WebApplicationFactory, then you will have to fire the whole request at http://localhost:1234/api/v1/car/ (as your test code is already doing), and somehow stub out whatever downstream call http://localhost:1234/api/v1/car/ is making through HttpClientService. Why did US v. Assange skip the court of appeal? To produce a test result, use the static methods in the Assert class to test actual results against expected results. I am using polly to handle retry (see below code). Can it still be improved? Do we want customer to have a slower experience while retrying to reach the API although we know the last few calls have been unsuccessful? But, to allow you to concentrate on delivering your business value rather than reinventing Polly's test wheel, keep in mind that the Polly codebase tests its own operation extensively. It will open the circuit for a certain amount of time which means it will not even try to execute the call but immediately throw an exception. Testing Your Code When Using Polly | no dogma blog These are a few samples from the documentation. The signatures use the TEST_CLASS and TEST_METHOD macros, which make the methods discoverable from the Test Explorer window. The following sections show the basic steps to get you started with C++ unit testing. I don't want to wait more than one minute in my tests. So, how does it test the integration between the HttpClient and the retry policy? Adding Polly retry policy to a mocked HttpClient? Implement HTTP call retries with exponential backoff with Polly How do I stop the Flickering on Mode 13h? Test Explorer discovers test methods in other supported frameworks in a similar way. For insight into how to do this, pull down the codebase and check out how Polly's own unit tests manipulate the clock. I have a few classes to demonstrate these scenarios, BusinessLogic.cs and OtherBusinessLogic.cs are the classes under test. Please view the original page on GitHub.com and not this indexable
