In your test code, inject an equivalent policy that doesn't do any waiting, eg Retry (3) // etc Extract static SystemClock to interface Can it still be improved? However, there are a lot of classes that re commonly used which are not refactored in .NET Core. It will retry for a number of time when receiving any exception. Perhaps you have code modules for which you already had unit tests, including success and failure cases. The 3rd parameter of onRetry is an int which represents retryAttempt, this can be added to logs. Making statements based on opinion; back them up with references or personal experience. I will answer the question at three different levels, and you can choose what suits best. Want to learn more about Polly? Instead it inherits HttpMessageInvoker class. Find them at Test adapter for Boost.Test and Test adapter for Google Test. English version of Russian proverb "The hedgehogs got pricked, cried, but continued to eat the cactus". (in response to "I cannot retrieve the HttpClient that has been configured with the Polly polly"), (to respond to the question title: "Test Polly retry polly configured via Startup.ConfigureServices() with ASP.NET Core API"). It is important to have the circuit working on a higher level than the call (i.e. For more information, see Run unit tests with Test Explorer. using AutoFixture . Is there a generic term for these trajectories? That could be with a full DI container, or just simple constructor injection or property injection, per preference. In the Add Reference dialog, choose the project(s) you want to test. I don't want to wait more than one minute in my tests. Run CTest tests from the CMake main menu. Updated Integration Test method Therefore it makes sense to be prepared and implement retry logic. A test adapter integrates unit tests with the Test Explorer window. Polly policies all fulfil execution interfaces (ISyncPolicy, ISyncPolicy, IAsyncPolicy and IAsyncPolicy). The circuit breaker keeps track of the number of exceptions. To test that the retry policy is invoked, you could make the test setup configure a fake/mock ILog implementation, and (for example) assert that the expected call .Error("Delaying for {delay}ms, ") in your onRetry delegate is made on the fake logger. On retry attempts, you want to change the parameters to reduce the chances of transient errors during the next retry attempt: Note: The Fallback policy might have been a good option here, but the purpose of this is to show how to do retries without delaying.

For failed tests, the message displays details that help to diagnose the cause. In the DI container set the handler to be applied to the injected http client, this will be avalible to the constructor of FooService. It reduces pressure on the server, which decreases the chances of running into transient errors. This property was added in .NET 5 (finally!).

Lets say you want to check if your code was retried 3 times and then successfully completed on the final attempt.
