testing everything. You can even copy & paste HTTP responses from your real web
server to create representative test cases. Or test that your code survives in
awkward-to-reproduce situations like 500 errors or slow-loading responses.


### Example

Use MockWebServer the same way that you use mocking frameworks like
[Mockito](https://github.com/mockito/mockito):

1. Script the mocks.
2. Run application code.

    int k1 = mixK1(input);
    int h1 = mixH1(seed, k1);

    return fmix(h1, Ints.BYTES);
  }

  @Override

    int low = (int) input;
    int high = (int) (input >>> 32);

    int k1 = mixK1(low);

    h1 = mixH1(h1, k1);
