### Question:
BindGoogleHadoopFileSystem { public void bindFileSystem(Configuration configuration) { LOG.debug("Binding GoogleHadoopFileSystem"); configuration.set(GS_FS_IMPLEMENTATION, GoogleHadoopFileSystem.class.getName()); configuration.set(GS_ABSTRACT_FS, GoogleHadoopFS.class.getName()); configuration.set(GCP_SERVICE_ACCOUNT_ENABLE, "true"); configuration.set(GCP_PROJECT_ID, "_THIS_VALUE_DOESNT_MATTER"); loadGSFileSystem(configuration); }  void bindFileSystem(Configuration configuration);  }### Answer:
@Test public void bindFileSystemTest() throws Exception { Configuration conf = new Configuration(); BindGoogleHadoopFileSystem binder = new BindGoogleHadoopFileSystem(); binder.bindFileSystem(conf); assertNotNull(conf.get(GCP_PROJECT_ID)); assertEquals("true", conf.get(GCP_SERVICE_ACCOUNT_ENABLE)); assertEquals(GoogleHadoopFileSystem.class.getName(), conf.get(GS_FS_IMPLEMENTATION)); assertEquals(GoogleHadoopFS.class.getName(), conf.get(GS_ABSTRACT_FS)); }
