我在Python中使用unittest和nose进行单元测试,但现在我正在使用py.test
unittest和nose总是在执行TestCase中的每个方法之前调用class.setUp
。
我怎么能用py.test做到这一点?
编辑:如果我添加:
def setup_class(cls):
cls.a = pypol.polynomial('x^3 - 2x^2 + x -5')
cls.b = pypol.polynomial('a^3 - 2x^2 - b + 3')
cls.c = pypol.polynomial('-x + 1')
cls.d = pypol.polynomial('a')
我收到所有错误:
_____________________________ TestPolynomial.testSetitem ______________________________
self = <test_pypol.TestPolynomial object at 0x97355ec>
def testSetitem(self):
> TestPolynomial.a[2] = (3, {'x': 3, 'y': 4})
E AttributeError: type object 'TestPolynomial' has no attribute 'a'
test_pypol.py:162: AttributeError
_____________________________ TestPolynomial.testDelitem ______________________________
self = <test_pypol.TestPolynomial object at 0x9735eac>
def testDelitem(self):
> del TestPolynomial.a[1:3]
E AttributeError: type object 'TestPolynomial' has no attribute 'a'
EDIT2:好的,我很蠢。我不得不把它放在TestCase内而不是外面。谢谢。

听起来你需要在测试类上定义setup_method
