### Question:
Container_Move_Simple extends DataSource { @Override protected int getDataSourceKey() { return 17218; } Container_Move_Simple(IDataSourceCallback iDataSourceCallback,
      HttpDataSourceCredentials credentials,
      String serverName);  Container_Move_Simple(
      IDataSourceCallback iDataSourceCallback,
      HttpDataSourceCredentials credentials,
      String serverName, boolean useTestServer); protected  Container_Move_Simple(IDataSourceCallback iDataSourceCallback,
      HttpDataSourceCredentials credentials, String serverName, boolean useTestServer,
      IDataSourceConnector connector); void setLocation(String location); void setSerialNo(String serialNo); void setUpdateBy(int updateBy); void setValidateLocation(boolean validateLocation);  }### Answer:
@Test public void getDataSourceKey() { int expected = 17218; int output = new Container_Move_Simple(null, null, null).getDataSourceKey(); assertEquals(expected, output); }
