“AssertionError: False is not True”当我试图运行我的代码时

Question

I am getting an error on this function:

def test_returns_true_when_feature_is_enabled(self):
    # Arrange
    mock_client = mock.MagicMock()
    mock_client.is_feature_enabled.return_value = True
    with patch.object(fullstack_service, 'get_optly_object', return_value=mock_client):
      with patch('services.js_validator.js_validator_service_rollout._get_account_id', return_value=123):
        # Act / Assert
        self.assertTrue(should_use_js_validator_service())

The error I get is:

AssertionError: False is not true
test/services_test/js_validator_test/js_validator_service_rollout_test.py:44: AssertionError

How can I fix this?

With a liberal use of the Inte.net, I found that on GeeksforGeeks , when the first parameter is False , assertTrue fails the test and prints the (seemingly optional) second parameter. When the first parameter is True , it doesn't do anything. The issue is that the function should_use_js_validator_service() , which you have passed to assertTrue , does not return a truthy value.
