Question

我在项目中创建了多个unit_test文件。当我独立运行所有测试文件时，所有文件都会通过所有测试用例。

但是当我通过TestRunner运行所有测试时，我得到错误

TypeError: 'NoneType' object is not callable.

我注意到由于修补而抛出此错误。

======================================================================
ERROR [0.001s]: test_create_pull_requests (test_custom_logs_manager.TestCustomLogManager)

代码段：

       MagicMock(return_value = MockCustomLogsPullTrack()))

我们的单元测试框架中存在类似的问题。如果您通过单元测试测试的方法具有装饰器“transaction.commit_manually”，则需要在单元测试方法中使用相同的装饰器。否则你得到这个激活“没有类型的对象不可调用”，这将不会给出实际问题的线索。
