On Windows, [Current] has been made considerably faster when
the current user is joined to a slow domain, which is the
usual case for many corporate users. The new implementation
performance is now in the order of milliseconds, compared to
the previous implementation which could take several seconds,

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.

      UnsignedLong unsignedValue = UnsignedLong.fromLongBits(value);
      assertThat(unsignedValue.toString()).isEqualTo(unsignedValue.bigIntegerValue().toString());
    }
  }

    for (int radix = Character.MIN_RADIX; radix <= Character.MAX_RADIX; radix++) {
      for (long l : TEST_LONGS) {
        UnsignedLong value = UnsignedLong.fromLongBits(l);
