I have the following method to create a Http client with a mocked response:

public static HttpClient GetMockedHttpClient(string responseContent, HttpStatusCode httpStatusCode)
        {
            var handlerMock = new Mock<HttpMessageHandler>(MockBehavior.Strict);
            handlerMock
               .Protected()
               .Setup<Task<HttpResponseMessage>>(
                  "SendAsync",
                  ItExpr.IsAny<HttpRequestMessage>(),
                  ItExpr.IsAny<CancellationToken>()
               )
               .ReturnsAsync(new HttpResponseMessage()
               {
                   StatusCode = httpStatusCode,
                   Content = new StringContent(responseContent),
               })
               .Verifiable();
            return new HttpClient(handlerMock.Object);
        }

How can I make the response dependent on a specific url, so that the setup only takes effect when the HttpClient is called with a given address?

CodePudding user response：

What you need to change is the line:

ItExpr.IsAny<HttpRequestMessage>(),

IsAny<HttpRequestMessage>() means the mock will catch any property of that type, if you want it to catch a specific uri you use Is<HttpRequestMessage>()

ItExpr.Is<HttpRequestMessage>(m => m.RequestUri == [your uri goes here]),

I would suggest using https://github.com/justeat/httpclient-interception. I had to run similar tests and it did the job, although I used it to mock whole client.
