python - 如何在不同的浏览器中使用 LiveServerTestCase 运行 selenium 测试？

Question

需要连续在不同的浏览器中运行测试(即首先在 firefox 中，接下来在 chrome 中进行相同的测试..)。解决此问题的最佳方法是什么？

我试图在 setUpClass 中加入循环，但它并没有真正帮助:

class UITest(LiveServerTestCase):

    fixtures = ['initial_test_data.json']

    @classmethod
    def setUpClass(self):
        for browser in [webdriver.Firefox(), webdriver.PhantomJS(), webdriver.Chrome()]:
            self.selenium = browser
            super(UITest, self).setUpClass()

Answer 1

为此，我使用了简单的装饰器，它通过指定的网络驱动程序运行测试:

import functools


def run_through_drivers(driver_pool='drivers'):
    def wrapped(test_func):
        @functools.wraps(test_func)
        def decorated(test_case, *args, **kwargs):
            test_class = test_case.__class__
            web_driver_pool = getattr(test_class, driver_pool)
            for web_driver in web_driver_pool:
                setattr(test_case, 'selenium', web_driver)
                test_func(test_case, *args, **kwargs)
        return decorated
    return wrapped

使用方法:

class UITest(LiveServerTestCase):

    fixtures = ['initial_test_data.json']
    selenium = None

    @classmethod
    def setUpClass(self):
        cls.drivers = WebDriverList(
            webdriver.Chrome(),
            webdriver.Firefox(),
            webdriver.PhantomJS
        )
        super(UITest, cls).setUpClass()

    @classmethod
    def tearDownClass(cls):
        for driver in cls.drivers:
            driver.quit()
        super(UITest, cls).tearDownClass()

    @run_through_drivers()
    def test_example(self):
        ...
