How to test HttpClientFactory with Moq - Code4IT

Mocking IHttpClientFactory is hard, but luckily we can use some advanced features of Moq to write better tests.

Was this NOT a thing when you wrote this article?

System.NotSupportedException HResult=0x80131515 Message=Unsupported expression: x => x.CreateClient() Extension methods (here: HttpClientFactoryExtensions.CreateClient) may not be used in setup / verification expressions. Source=Moq

Hopefully I can find something out there on how to fix this. : /

The answer is that you must created a "Named" HttpClient via the .CreateClient("this can be empty") method.

Yes, if you use named HttpClients, you have to specify the name of the client in the tests.

Otherwise, the solution I shared is fine. You can download and run the tests here.
