他提示我，保存图片没有拓展名，但是我已经加了，但是他还是会把，没有加拓展名的文件保存到我的case里，这里我的代码
class FirstDdtCase(unittest.TestCase):
def setUp(self):
self.driver = webdriver.Chrome()
self.driver.get('http://www.5itest.cn/register?goto=/')
self.driver.maximize_window()
self.login = RegisterBusiness(self.driver)
def tearDown(self):
time.sleep(2)
# _outcome.errors 可以拿到当前运行case和运行信息（list）
for method_name, error in self._outcome.errors: # 判断error有没有，如果有就进行截图
if error:
case_name = self._testMethodName # ._testMethodName 有错误的时候直接拿到case的名字
filter_path = os.path.join('../report/' + case_name + '.png')
self.driver.save_screenshot(filter_path)
self.driver.close()
# print('这个是case的后置条件')
@ddt.data(
