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.

      assertThat(unsignedValue.toString()).isEqualTo(unsignedValue.bigIntegerValue().toString());
    }
  }

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

    assertTrue(multimap.containsEntry("bar", 3));
    assertEquals(4, (int) entrya.getValue());
    assertEquals(3, (int) entryb.getValue());
  }

  @GwtIncompatible // unreasonably slow
  public void testEntriesIteration() {
    List<Entry<String, Integer>> addItems =
        ImmutableList.of(
            immutableEntry("foo", 99), immutableEntry("foo", 88), immutableEntry("bar", 77));

(like HTTP/2).

URLs that share the same address may also share the same underlying TCP socket connection. Sharing a connection has substantial performance benefits: lower latency, higher throughput (due to [TCP slow start](https://www.igvita.com/2011/10/20/faster-web-vs-tcp-slow-start/)) and conserved battery. OkHttp uses a [ConnectionPool](https://square.github.io/okhttp/4.x/okhttp/okhttp3/-connection-pool/) that automatically reuses HTTP/1.x connections and multiplexes HTTP/2 connections....
