OkHttp MockWebServer fails to accept connections when restarted

Question

I\'m using the OkHttp MockWebServer to mock my server responses for unit tests.

It works great for the first test, but on the 2nd test my client fails with:

Answer 1

Your second request is using the URL of the first MockWebServer instance. (Each instance has a distinct URL.)

Answer 2

This localhost connection fails because it does not belong tot he mock server. Use this instead (mockHelper.getHost()).willReturn(okhttpMockWebServer.url("/").toString())
