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.

 * or both.
 *
 * ## Authentication Retries
 *
 * If your authentication may be flaky and requires retries you should apply some policy
 * to limit the retries by the class of errors and number of attempts.  To get the number of
 * attempts to the current point use this function.
 *
 * ```java
 * private int responseCount(Response response) {
 *   int result = 1;

            refusedStreamCount++
            if (refusedStreamCount > 1) {
              noNewExchangesEvent = !noNewExchanges
              noNewExchanges = true
              routeFailureCount++
            }
          }

          e.errorCode == ErrorCode.CANCEL && call.isCanceled() -> {
            // Permit any number of CANCEL errors on locally-canceled calls.
          }

during compilation indicate errors in your style and can be viewed in the
`checkstyle-result.xml` file.

Some general advice

- Don’t change public API lightly, avoid if possible, and include your reasoning in the PR if essential.  It causes pain for developers who use OkHttp and sometimes runtime errors.

    val request2 = server.takeRequest()
    assertThat(tlsVersions).contains(request2.handshake?.tlsVersion)
  }
