unittest-ddt报错AttributeError: type object ‘forTestDDT‘ has no attribute ‘test

unittest 添加多个ddt数据驱动后，报错：

FAILED (errors=1)Error
Traceback (most recent call last):File "D:\Anaconda3\lib\unittest\case.py", line 60, in testPartExecutoryieldFile "D:\Anaconda3\lib\unittest\case.py", line 676, in runself._callTestMethod(testMethod)File "D:\Anaconda3\lib\unittest\case.py", line 633, in _callTestMethodmethod()File "D:\Anaconda3\lib\unittest\loader.py", line 34, in testFailureraise self._exceptionFile "D:\Anaconda3\lib\unittest\loader.py", line 169, in loadTestsFromNameparent, obj = obj, getattr(obj, part)
AttributeError: type object 'forTestDDT' has no attribute 'test_2'

百度解决方案如下：

原因：
运行的时候光标的位置放在 test_2方法里面了，加了ddt后，运行时要先识别装饰的类。若将光标放在某一个方法后面的话，测试用例只会执行当前的方法，ddt识别不到类，就会报错。将光标放到外面，则运行通过，或者加main方法，再运行，也不会报错
