class_docstr: The class is the base class for tests under the remote module. It can provide different mocked environments for tests, and each test should inherit this class.
      Note that users **SHOULD NOT** override the setUp function, and they should implement _setUp for initialization instead.
  
  Usage: Users should inherit this class to implement the unit tests for remote modules. The class must be decorated with the env_config declared above. (e.g., @env_config_for_test at line 19)
  
  Example: Please refer to parl/remote/tests/mocking_env_test.py.
code: def patch(self, target, **kwargs):
      p = mock.patch(target, **kwargs)
      p.start()
      self.addCleanup(p.stop)

label_desc: Use image node_id 1 for calling the MockingEnv obj's underlying member method code with example usage: obj.patch(target) without return types
