1  类里使用Fixture

        Pytest中夹具（Fixture）有几种生命周期：function->model->class->session->packages，其中默认为function。    

import pytest
from Common.logger import Log
from Common.Operator import *
from Common.Logins import Logins
from Page.Credentials.CredentialsPage import CredentialsPage as cp
from selenium.webdriver.common.by import By
import allurelog = Log("TestJohnDeere")class TestJohnDeere:driver = Nonelg = Nonepage = Nonecoll = (By.XPATH, '//*[@id="nav_arrow"]/div')@pytest.fixture()  # 使用默认值def begin(self):log.info('--------开始测试John Deere Credentials功能--------')self.driver = browser("chrome")self.lg = Logins()self.lg.login(self.driver, 'atcred@iicon004.com', 'Win.12345')self.driver.implicitly_wait(10)self.page = cp()ac = self.lg.get_attribute(self.coll, 'class')while True:if ac != 'icn collapse':ar = (By.ID, 'nav_arrow')self.page.click(ar)continueelse:breakself.lg.click(self.page.johndeere_menu)time.sleep(1)self.lg.switch_to_iframe(self.page.right_iframe)yield self.lgself.driver.quit()def add_jdlink(self, begin):log.info('点击 JD Link 的Add')if not begin.is_clickable(self.page.jdlink_add_btn):time.sleep(2)try:begin.click(self.page.jdlink_add_btn)time.sleep(1)self.driver.switch_to.window(self.driver.window_handles[1])time.sleep(2)txt = begin.get_text(self.page.jdlink_page_signin_lable)except Exception:log.info('Add 跳转失败!')return Falseelse:log.info('Add 跳转成功!')self.driver.switch_to.window(self.driver.window_handles[0])if txt == 'Sign In':return Trueelse:return False@allure.feature("测试Credentials功能")@allure.story("测试JD Link Credentials设置功能")def test_addJDlink(self, begin):"""测试Add JD Link功能"""res = self.add_jdlink(begin)if res:log.info('Add JD Link 测试成功！')else:log.info('Add JD Link 测试失败！')assert resif __name__ == '__main__':pytest.main(['-vs', 'TestJohnDeere.py'])  # 主函数模式

2  指定Fixture范围

        在类外写Fixture，通过@pytest.para.usefixtures("fixture name")来调用。

    

import pytest
from Common.logger import Log
from Common.Operator import *
from Common.Logins import Logins
from selenium.webdriver.common.by import By
import allurelog = Log("test_logins")# 定义fixture
@pytest.fixture(scope='class')
def starts():driver = browser("chrome")lg = Logins()lg.login(driver)driver.implicitly_wait(10)yield lgdriver.quit()# 使用fixtures
@pytest.mark.usefixtures('starts')
class TestLogins(Operator):home_log = (By.ID, 'button_home')btnuser = (By.ID, 'btnuser')loc = (By.ID, 'spanusername')# 修改密码元素changePwBtn_loc = (By.XPATH, '//*[@id="usermenu_panel"]/ul/li[2]/table/tbody/tr/td[2]/span')oldpw_loc = (By.ID, 'txt_old_pass')newpw_loc = (By.ID, 'txt_new_pass')confirmpw_loc = (By.ID, 'txt_new_pass2')changeOk_loc = (By.ID, 'button_submit')# 退出登录相关元素logout_loc = (By.XPATH, '//*[@id="usermenu_panel"]/ul/li[3]/table/tbody/tr/td[2]/span')loginB_loc = (By.ID, 'btn_login')@allure.feature("用户登录相关测试")@allure.story("测试登录功能")def test_login(self, starts):starts.click(self.home_log)time.sleep(2)starts.click(self.btnuser)time.sleep(1)displayname = starts.find_element(self.loc).textstarts.click(self.btnuser)assert displayname == 'Auto Test'def change_password(self, starts):starts.driver.refresh()time.sleep(2)starts.click(self.btnuser)try:starts.click(self.changePwBtn_loc)time.sleep(1)except Exception:log.info('open change password failed!')return Falseelse:starts.send_keys(self.oldpw_loc, 'Win.12345')starts.send_keys(self.newpw_loc, 'Win.12345')starts.send_keys(self.confirmpw_loc, 'Win.12345')time.sleep(1)try:starts.click(self.changeOk_loc)time.sleep(2)starts.driver.switch_to.alert.accept()time.sleep(1)except Exception:return Falseelse:return True@allure.feature("用户登录相关测试")@allure.story("测试修改密码")def test_change_password(self, starts):assert self.change_password(starts)@allure.feature("用户登录相关测试")@allure.story("测试退出功能")def test_logout(self, starts):starts.driver.refresh()time.sleep(3)starts.click(self.btnuser)time.sleep(1)starts.click(self.logout_loc)# 判断是否正确退出res = starts.is_text_in_value(self.loginB_loc, 'LOGIN')assert resif __name__ == '__main__':pytest.main(['-v', 'Testlogins.py'])

3  fixture和参数化同时使用

        fixture中不使用参数，测试用例使用参数化。
