多个测试模块的设置和拆卸方法

Question

我有许多测试，分散在不同的测试模块和类中。我需要在运行测试之前/之后启动/拆除docker容器，但The method add(enrollment) in the type LinkedList<enrollment> is not applicable for the arguments (String) The method add(int, enrollment) in the type LinkedList<enrollment> is not applicable for the arguments (int) The method add(int, enrollment) in the type LinkedList<enrollment> is not applicable for the arguments (int) The method add(enrollment) in the type LinkedList<enrollment> is not applicable for the arguments (String) The method add(enrollment) in the type LinkedList<enrollment> is not applicable for the arguments (String) at enrollment.main(enrollment.java:44) 和setUpClass()似乎都不合适。如何为多个模块指定设置和拆卸方法？

Answer 1

为您的所有测试创建一个基类，您可以在其中放置常用的setUpClass和tearDownClass方法：

class MyTestCase(unittest.TestCase):
    def setUpClass(self):
        ...set up docker stuff...

    def tearDownClass(self):
        ...tear down docker stuff...

现在让所有测试类继承自该基类：

from mymodule.mytestcase import MyTestCase

class TestMyNiftyFeature(MyTestCase):
    def test_feature(self):
        ...test things here...

这将在每个类之前和之后运行setup / teardown方法，这通常是你想要的，因为你希望你的测试是自包含的，这样你就可以在一个文件中运行测试而不在另一个文件中运行测试。
