我最近从使用nose 更改为nose2，但是我的很多测试代码似乎在此过程中已损坏。特别是我在测试类“self.mir_axis”中放入的初始化变量给出了这个错误：

mirror_index = mirror_matrix.index(self.mir_axis)
AttributeError: 'TestConvert' object has no attribute 'mir_axis'

这曾经适用于nose，但是对于nose2，我的init变量由于某种原因不再注册。我在这里错过了什么吗？我使用 python 2.7.3，并将 eclipse 作为 IDE 顺便说一句。

        self.__class__.counter += 1 # increase counter when run
        if self.__class__.counter > 3:

我发现您发布的代码段存在两个问题：

第一个def _init__(self):是缺少下划线；它应该是def __init__(self):

第二个（似乎是错误的原因）是 , , 中的第一行_init__应该mir_axes = ['xy', '-xy', ...是self.mir_axes = ...

根据Coverage.py名声的Ned Batchelder的说法，你应该使用setUp而不是__init__不管。:)
