我正在使用 Python 3.6.5 和以下库:
- Appium-Python-Client==0.26
- unittest2==1.1.0
- Selenium ==3.5.0
- pytest==3.6.3
现在我需要截屏以防测试失败,所以我故意做了一个错误的陈述
self.driver.find_element_by_css_selector('test')
.
我正在使用 sys.exc_info()
。但是,当我使用以下命令执行以下代码时:py.test untitled.py
或 python3 -m unittest untitled.py
它不会捕获它。
代码:
import sys, time, unittest2
from selenium import webdriver
class FB360(unittest2.TestCase):
def setUp(self):
self.driver = webdriver.Chrome()
def test_user_can_login(self):
self.driver.get('https://www.google.co.in')
self.driver.find_element_by_css_selector('test')
def tearDown(self):
print(sys.exc_info())
if sys.exc_info()[0]:
test_method_name = self._testMethodName
self.driver.save_screenshot(test_method_name + str(time.time()) + '.png')
self.driver.quit()
if __name__ == '__main__':
unittest2.main()
O/P:
(None, None, None)
E
====================================================================== ERROR: test_user_can_login (untitled.FB360)

我的基础:
print(sys.exc_info())
打印:(无,无,无)。这意味着即使我收到以下异常,我的测试用例也已通过:
selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {"method":"css selector","selector":"test"}
- 由于
sys.exc_info())
返回 (None, None, None) 在if
条件下执行不会完成
所以我主要担心的是,为什么即使我收到 NoSuchElementException,sys.exc_info())
也会返回 (None, None, None)?
最佳答案
我用它来截取失败测试的屏幕截图
@pytest.fixture()
def browser(request):
options = Options()
options.add_argument("--headless") # Runs Chrome in headless mode.
_chrome = webdriver.Chrome(options=options)
failed_before = request.session.testsfailed
yield _chrome
if request.session.testsfailed != failed_before:
test_name = request.node.name
take_screenshot(_chrome, test_name)
_chrome.close()
def take_screenshot(browser, test_name):
screenshots_dir = "path_to/functional_tests/failure_screenshots"
screenshot_file_path = "{}/{}.png".format(screenshots_dir, test_name)
browser.save_screenshot(
screenshot_file_path
)
