driver在不同fixture之间共享

前言：

如果要用到fixture函数的返回值，先return出来，用例传fixture对象就能直接调用了。

fixture参数共享driver

实现场景：

1、用例开始前只打开一次浏览器

2、每个用例开始前，都打开首页，从首页开始运行

3、用例执行完成最后，关闭浏览器

实现方法

1、先定义一个driver函数，设置scope=‘module’,在当前模块全局生效，这样可以做到只启动一次浏览器，就能执行全部用例

2、定义一个start函数，设置scope=‘function’，在每个用例前调用一次

3、addfinalizer终结函数可以在用例全部执行完成后，最后调用driver.quit()退出浏览器

from selenium import webdriver
import pytest
import time

@pytest.fixture(scope='module')
def driver(request):
    driver=webdriver.Chrome(r"D:chromedriver.exe")
    print("start chrome浏览器")
    
    def end():
        driver.quit()
    
    request.addfinalizer(end)
    return driver

@pytest.fixture(scope='function')
def start(driver):
    print("open baidu.com")
    driver.get("https://wwww.baidu.com")
    time.sleep(1)

def test_01(driver,start):
    print("用例1")
    driver.find_element_by_id("kw").send_keys("hello")
    driver.find_element_by_id("su").click()
    time.sleep(1)
    print(driver.title)
    assert 'hello' in driver.title

def test_02(driver,start):
    print("用例2")
    driver.find_element_by_id("kw").send_keys("hello world!")
    driver.find_element_by_id("su").click()
    time.sleep(1)
    print(driver.title)
    assert "hello world!" in driver.title

if __name__ == '__main__':
    pytest.main(['-v','test_baidu.py'])

用例用Classs实现

from selenium import webdriver
import  pytest
import  time

@pytest.fixture(scope='module')
def driver(request):
    driver=webdriver.Chrome(r'D:chromedriver.exe')
    print("start chrome浏览器")

    def end():
        driver.quit()
    request.addfinalizer(end)
    return  driver

class TestBaidu():
    @pytest.fixture(scope='function',autouse=True)#zutouse=True自动调用fixture功能
    def start(self,driver):
        print("open baidu.com")
        driver.get("https://www.baidu.com")
        time.sleep(1)

    def test_01(self,driver):
        print("用例01")
        driver.find_element_by_id('kw').send_keys("hello")
        driver.find_element_by_id('su').click()
        time.sleep(1)
        print(driver.title)
        assert 'hello' in driver.title

    def test_02(self,driver):
        print("用例02")
        driver.find_element_by_id("kw").send_keys("hello world!")
        driver.find_element_by_id("su").click()
        time.sleep(1)
        print(driver.title)
        assert 'hello world!' in driver.title

if __name__ == '__main__':
    pytest.main(['-v','test_baiduClass.py'])
