### Question:
BootstrapEnvironment { public RestfulServerConfiguration getRestfulServerConfiguration() { return new RestfulServerConfiguration(Integer.parseInt(getValue(EnvironmentArgument.PORT))); } private  BootstrapEnvironment(); String getFrameworkHostPort(); MesosConfiguration getMesosConfiguration(); ZookeeperConfiguration getZookeeperConfiguration(); RestfulServerConfiguration getRestfulServerConfiguration(); FrameworkConfiguration getFrameworkConfiguration(); Optional<JobEventRdbConfiguration> getJobEventRdbConfiguration(); HashMap<String, String> getJobEventRdbConfigurationMap(); Optional<String> getMesosRole();  }### Answer:
@Test public void assertGetRestfulServerConfiguration() { RestfulServerConfiguration restfulServerConfig = bootstrapEnvironment.getRestfulServerConfiguration(); Assert.assertThat(restfulServerConfig.getPort(), Is.is(8899)); }
