python selenium全部在一个会话浏览器中进行测试

Question

I have a question.

I have 10 classes in 10 files and one main class and class with user log. I run all tests in the main class. I would like to run 10 at once. At present, the browser opens up to 10 times with each class. I would like 10 tests to take place in 1 browser session. It is possible? Because I can not do this. Please, help me, thank you! Me login class:

class Login(unittest.TestCase):
@classmethod
def setUpClass(cls):
    cls.browser = webdriver.Chrome()

def setUp(self):
    self.browser.get("www")
    username = self.browser.find_element_by_id("username")
    password = self.browser.find_element_by_id("password")
    username.send_keys("aaaa")
    password.send_keys("ssswww")
    self.browser.find_element_by_id("button").click()

def tearDown(self):
    self.browser.get("about:blank")

@classmethod
def tearDownClass(cls):
    cls.browser.quit()

Answer 1

I would like 10 tests to take place in 1 browser session.

This code will open one browser and then use it for multiple tests. I'm not sure that this is the best way to do selenium tests and you may want to clear cookies as shown in the accepted answer there but I'll leave that to you.

import time

import pytest
from selenium import webdriver


# if you omit `scope='module'`, every test will open a new browser
# this way it will use the same browser for each test
@pytest.fixture(scope='module')
def driver():
    d = webdriver.Chrome()
    # d.get("www")
    # username = d.find_element_by_id("username")
    # password = d.find_element_by_id("password")
    # username.send_keys("aaaa")
    # password.send_keys("ssswww")
    # d.find_element_by_id("button").click()
    yield d
    d.quit()


@pytest.mark.parametrize('url', (
    'https://google.com',
    'https://yahoo.com',
    'https://bing.com',
))
def test_hmm(driver, url):
    driver.get(url)
    time.sleep(3)
    assert True

Console:

$ pytest hmm.py

capybara-py , which provides a layer on top of Selenium, uses a single browser session, taking care of the necessary cleanup for you:

import capybara

class Login(unittest.TestCase):
    def setUp(self):
        self.page = capybara.dsl.page
        self.page.visit("http://www.example.com")
        self.page.fill_in("Username", value="aaaa")
        self.page.fill_in("Password", value="ssswww")
        self.page.click_button("Sign in")

    def tearDown(self):
        capybara.reset_sessions()

You can simply initialize Chrome webdriver inside your Login class, instead of initializing it in the setUp() class. This way, the browser will open once for each test.
