Question

我是unittest的新手，我不知道为什么会收到此错误：

runTest (__main__.TestTimeInterval)
No test ... Traceback (most recent call last):
  File "/Users/bli1/Development/Trinity/qa-trinity/python_lib/qe/tests/test_timestamp_interval.py", line 122, in <module>
    sys.exit(main(sys.argv))
  File "/Users/bli1/Development/Trinity/qa-trinity/python_lib/qe/tests/test_timestamp_interval.py", line 110, in main
    result_set = runner.run(suite)
  File "/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/unittest/runner.py", line 168, in run
    test(result)
  File "/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/unittest/suite.py", line 87, in __call__
    return self.run(*args, **kwds)
  File "/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/unittest/suite.py", line 125, in run
    test(result)
  File "/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/unittest/case.py", line 625, in __call__
    return self.run(*args, **kwds)
  File "/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/unittest/case.py", line 555, in run
    testMethod = getattr(self, self._testMethodName)
AttributeError: 'TestTimeInterval' object has no attribute 'runTest'

我想创建一个简单的测试，看看是否一切正常，但我得到了上面的错误。我将测试添加到套件中，然后使用.run()

运行它

class TestTimeInterval(unittest.TestCase):
    def __init__(self, log, runtag, interval, path_file):
        super(TestTimeInterval, self).__init__()
        self.interval = interval
        self.path_file = path_file
        self.log = log
        self.runtag = runtag

    def test_record(self):
        self.assertTrue(1 > 0)

    parser = argparse.ArgumentParser(description=main.__doc__)
    parser.add_argument("file", metavar="FILE",

    log = logging.getLogger(me)
    logfile = args.runtag + ".log"

    log.addHandler(logging.FileHandler(logfile))

        suite = unittest.TestSuite()
        print(args)
        suite.addTest(TestTimeInterval(log, args.runtag, args.interval, args.file))
        try:

    return exit_code

您几乎不需要自己创建TestSuite和TestRunner。通常，您可以执行以下操作：

# my_test.py
import unittest

class Something(object):
    def __init__(self):
        self.foo = 1

class TestSomething(unittest.TestCase):
    def setUp(self):
        super(TestSomething, self).setUp()
        self.something = Something()

    def test_record(self):
        self.assertTrue(1 > 0)

    def test_something_foo_equals_1(self):
        self.assertEqual(self.something.foo, 1)


if __name__ == '__main__':
    unittest.main()

现在，要运行测试，只需执行脚本。

python my_test.py

AttributeError：对象没有属性＆＃39; runTest＆＃39;
