背景:
我将 py.test 与 pytest-selenium 一起使用,现在我想在断言失败时截取页面的屏幕截图。
目前我已经在我的基页对象类中定义了小助手方法:
class PageBase(object):
def __init__(self,driver):
self.driver = driver
self.fake = Factory.create()
def screenshot(self,name):
self.driver.save_screenshot(datetime.now().strftime('%Y-%m-%d %H:%M:%S') + 'scr_'+name+'.png')
@contextmanager
def wait_for_page_load(self, timeout=45):
old_page = self.driver.find_element_by_tag_name('html')
yield
WebDriverWait(self.driver, timeout).until(
EC.staleness_of(old_page)
)
问题是我想让它自动化机制而不是“手动”使用:
(测试类示例):
class TestLogin:
@allure.feature('Ability to login into admin panel')
def test_admin_login(self, prepare, page):
print URLMap.admin('test')
driver = prepare
driver.get(URLMap.admin(page))
login_page = LoginPage(driver)
assert login_page.is_page_correct(),'Login page not loaded correctly'
login_page.fill_login_data('testadmin','testadmin')
login_page.click_login_button()
assert login_page.is_user_logged_in(),'User cannot log in with provided credentials'
login_page.screenshot(page+'_logged_in')
如何为每个断言失败运行某些方法?
最佳答案
我个人没有使用过,但这可能是您的解决方案:
