void awaitLatchUninterruptibly() {
      Uninterruptibles.awaitUninterruptibly(latch);
    }

    @Override
    boolean awaitLatchUninterruptibly(long timeout, TimeUnit unit) {
      return Uninterruptibles.awaitUninterruptibly(latch, timeout, unit);
    }

    @Override
    long getCount() {
      return latch.getCount();
    }
  }

Here's a complete example:

### Java
```java
public void test() throws Exception {
  // Create a MockWebServer. These are lean enough that you can create a new
  // instance for every unit test.
  MockWebServer server = new MockWebServer();

  // Schedule some responses.
  server.enqueue(new MockResponse.Builder()
      .body("hello, world!")
      .build());
  server.enqueue(new MockResponse.Builder()

      bytesPerPeriod: Long,
      period: Long,
      unit: TimeUnit,
    ): Builder =
      apply {
        throttleBytesPerPeriod = bytesPerPeriod
        throttlePeriodNanos = unit.toNanos(period)
      }

    public fun headersDelay(
      delay: Long,
      unit: TimeUnit,
    ): Builder =
      apply {
        headersDelayNanos = unit.toNanos(delay)
      }

    /**

   * cast:
   *
   * <pre>
   *   {@code @SuppressWarnings("unchecked") // guaranteed by invokeAll contract}
   *   {@code List<ListenableFuture<T>> futures = (List) executor.invokeAll(tasks, timeout, unit);}
   * </pre>
   *
   * @return a list of {@code ListenableFuture} instances representing the tasks, in the same
   *     sequential order as produced by the iterator for the given task list. If the operation did

cluster, it is recommended to write unit tests or REST tests instead.

In short, most new functionality should come with unit tests, and optionally
REST tests to test integration.

==== Refactor code to make it easier to test

Unfortunately, a large part of our code base is still hard to unit test.
Sometimes because some classes have lots of dependencies that make them hard to

        double target = value;
        String unit = ""; // TODO l10n?
        String format = "0.#";
        if (value < 1024) {
            format = "0";
        } else if (value < 1024L * 1024L) {
            target /= 1024;
            unit = "K";
        } else if (value < 1024L * 1024L * 1024L) {
            target /= 1024;
            target /= 1024;
            unit = "M";

          return -1L
        }
      },
    )
    return null
  }
