Python selenium -如何运行Selenium

Question

我第一次在运行python selenium时遇到了问题：

from selenium import webdriver 
from selenium.webdriver.common.keys import Keys 
import unittest

class segfam(unittest.TestCase):
    def setUp(self):
        self.driver=webdriver.chrome("/Users/tomersegal/Downloads/chromedriver")

    def test_blabla(self):
        driver=self.driver
        driver.get("https://www.google.co.il/")
        assert "Google" in driver.title

这是我的错误：

Ran 0 tests in 0.000s

OK
Launching unittests with arguments python -m unittest discover -s /Users/tomersegal/PycharmProjects/pythonProject1 -t /Users/tomersegal/PycharmProjects/pythonProject1 in /Users/tomersegal/PycharmProjects/pythonProject1


Process finished with exit code 0

Empty suite

Answer 1

在使用unittest框架时，必须从__main__函数调用它，如下所示：

if __name__ == "__main__":
    unittest.main()

因此，您的有效代码块将是：

from selenium import webdriver 
from selenium.webdriver.common.keys import Keys 
import unittest

class segfam(unittest.TestCase):
    def setUp(self):
        self.driver=webdriver.Chrome("/Users/tomersegal/Downloads/chromedriver")

    def test_blabla(self):
        driver=self.driver
        driver.get("https://www.google.co.il/")
        assert "Google" in driver.title

if __name__ == "__main__":
    unittest.main()

PS:注意铬向 chrome 的变化
