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);

    assertSame(immutable, Multimaps.unmodifiableMultimap(immutable));
    assertSame(immutable, Multimaps.unmodifiableMultimap((Multimap<String, Integer>) immutable));
  }

  public void testUnmodifiableArrayListMultimap() {
    checkUnmodifiableMultimap(
        ArrayListMultimap.<@Nullable String, @Nullable Integer>create(), true);
