我有一个方法(run_script)想测试.具体来说,我想测试一个调用subprocess.Popen发生.测试subprocess.Popen使用某些参数进行测试会更好.当我运行测试但是我得到了TypeError: 'tuple' object is not callable.

如何测试我的方法以确保实际使用模拟调用子进程？

@mock.patch('subprocess.Popen')
def run_script(file_path):
  process = subprocess.Popen(['myscript', -M, file_path], stdout=subprocess.PIPE)
  output,err = process.communicate()
  return process.returncode

def test_run_script(self, mock_subproc_popen):
  mock_subproc_popen.return_value = mock.Mock(communicate=('ouput','error'), returncode=0)
  am.account_manager("path")
  self.assertTrue(mock_subproc_popen.called)
