我有一個測試，作爲unittest.TestCase的一個子類，我使用裝飾器。在我的unittest.TestCase類上使用裝飾器後，未使用unittest.TestLoader（）加載測試
import unittest
from selenium import webdriver
import sys
SAUCE_USERNAME = 'xxx'
SAUCE_ACCESS_KEY = 'xxx'
sauce = SauceClient(SAUCE_USERNAME, SAUCE_ACCESS_KEY)
browsers = [{"platform": "Mac OS X 10.9",
"browserName": "chrome",
"version": "31"},
{"platform": "Windows 8.1",
"browserName": "internet explorer",
"version": "11"}]
def on_platforms(platforms):
def decorator(base_class):
module = sys.modules[base_class.__module__].__dict__
for i, platform in enumerate(platforms):
d = dict(base_class.__dict__)
d['desired_capabilities'] = platform
name = "%s_%s" % (base_class.__name__, i + 1)
module[name] = new.classobj(name, (base_class,), d)
return decorator
@on_platforms(browsers)
class MyTestSuite(unittest.TestCase):
@classmethod
def setUpClass(cls):
cls.desired_capabilities['name'] = cls.id()
sauce_url = "http://%s:%[email protected]:80/wd/hub"
cls.driver = webdriver.Remote(
desired_capabilities=cls.desired_capabilities,
command_executor=sauce_url % (SAUCE_USERNAME,SAUCE_ACCESS_KEY))
cls.driver.implicitly_wait(30)
def test_1from_sauce(self):
pass
def test_2from_sauce(self):
pass
@classmethod
def tearDownClass(cls):
cls.driver.quit()
if __name__ == "__main__":
suite =unittest.TestLoader().loadTestsFromTestCase(Registration)
unittest.TextTestRunner(verbosity=1).run(suite)
問題是，當我使用CLI運行此代碼，我得到這個錯誤：
File "MyTestSuite.py", line xxx, in <module>
suite = unittest.TestLoader().loadTestsFromTestCase(Registration)
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/unittest/loader.py", line 50, in loadTestsFromTestCase
if issubclass(testCaseClass, suite.TestSuite):
TypeError: issubclass() arg 1 must be a class
這個錯誤消失，當我註釋掉@on_platforms裝飾。另外當我使用這個裝飾器時，MyTestSuite type is "Nonetype"，當我刪除它時，MyTestSuite的類型更改爲"type"。問題來自哪裏？
