pytest 参数化测试是否适用于基于单元测试类的测试? [英] Does pytest parametrized test work with unittest class based tests?

问题描述

我一直在尝试将参数化的 @pytest.mark.parametrize 测试添加到基于类的单元测试中.

I've been trying to add parametrized @pytest.mark.parametrize tests to a class based unittest.

class SomethingTests(unittest.TestCase):
    @pytest.mark.parametrize(('one', 'two'), [
        (1, 2), (2, 3)])
    def test_default_values(self, one, two):
        assert one == (two + 1)

但是参数化的东西没有发挥作用:

But the parametrized stuff didn't kick in:

TypeError: test_default_values() takes exactly 3 arguments (1 given)

我已经切换到简单的基于类的测试(没有单元测试).但我想知道是否有人尝试过并且有效.

I've switched to simple class based tests (without unittest). But I'd like to know if anyone tried it and it worked.

推荐答案

根据 pytest 文档:

unittest.TestCase 方法不能直接接收fixture函数作为实施的论点可能会影响运行常规的unittest.TestCase 测试套件.

unittest.TestCase methods cannot directly receive fixture function arguments as implementing that is likely to inflict on the ability to run general unittest.TestCase test suites.
