Python unittest 上的执行顺序 [英] Execution order on Python unittest

问题描述

我需要为我的测试设置一个执行顺序，因为我需要在其他数据之前验证一些数据.可以下单吗?

I need to set an order of execution for my tests, because I need some data verified before the others. Is possible to set an order?

class OneTestCase(unittest.TestCase):
    def setUp(self):
        # something to do
    def test_login (self):
        # first test
        pass
    def test_other (self):
        # any order after test_login
    def test_othermore (self):
        # any order after test_login
if __name__ == '__main__':
    unittest.main()

推荐答案

最好不要这样做.

测试应该是独立的.

做你想做的最好的事情就是将代码放入测试调用的函数中.

To do what you want best would be to put the code into functions that are called by the test.

像这样:

def assert_can_log_in(self):
    ...

def test_1(self):
    self.assert_can_log_in()
    ...

def test_2(self):
    self.assert_can_log_in()
    ...

甚至可以拆分测试类并将断言放入setUp函数中.

Or even to split the test class and put the assertions into the setUp function.

class LoggedInTests(unittest.TestCase):
    def setUp(self):
        # test for login or not - your decision

    def test_1(self):
        ...

当我拆分班级时，我经常编写更多更好的测试，因为测试被拆分了，我可以更好地了解所有应该测试的案例.

When I split the class I often write more and better tests because the tests are split up and I can see better through all the cases that should be tested.
