### Question:
WrappedHttpClientConfig { public int getIoThreadCount() { return ioThreadCount; } protected  WrappedHttpClientConfig(Builder builder); HttpClientConfig getHttpClientConfig(); int getIoThreadCount();  }### Answer:
@Test public void builderBuildsWithGivenIoThreadCount() { HttpClientConfig givenConfig = new HttpClientConfig.Builder("http: WrappedHttpClientConfig.Builder builder = new WrappedHttpClientConfig.Builder(givenConfig); int ioThreadCount = new Random().nextInt(1000) + 10; builder.ioThreadCount(ioThreadCount); WrappedHttpClientConfig config = builder.build(); assertEquals(ioThreadCount, config.getIoThreadCount()); }
