我有一些测试用例,如下所述。但是我想在其他所有测试用例之后重复test1()。我怎样才能做到这一点?
@pytest.mark.test1()
@pytest.mark.parametrize(a,b,c)
def test_test1():
......
......
@pytest.mark.test2()
def test_test2():
......
......
@pytest.mark.test3()
def test_test3():
......
......
run test1() again
最佳答案
您可以通过实现pytest_collection_modifyitems
挂钩来修改要执行的测试列表。示例:在您的根目录中,创建一个名为conftest.py
的文件,并将钩子添加到其中:
def pytest_collection_modifyitems(session, config, items):
test1s = [item for item in items if item.function.__name__ == 'test_test1']
items.extend(test1s)
现在,
test_test1
将被添加到已经收集的测试列表中,并执行两次:$ pytest -v

一个更优雅的解决方案是使用自定义标记,我们将其命名为
my_repeat
:@pytest.mark.my_repeat
@pytest.mark.parametrize(a,b,c)
def test_test1():
...
适应
conftest.py
中的钩子:def pytest_collection_modifyitems(session, config, items):
repeats = [item for item in items if item.get_marker('my_repeat')]
items.extend(repeats)
