GAE Python 单元测试运行程序

Question

我在 Google 的 Cloud Endpoints 框架上有一个 Python API 运行ning。

我正在尝试使用 dev_appserver.

为我的单元测试实现运行ner

我已经复制并改编了 Google 提供的关于此的内容，只是编辑了一点使其成为运行 devappserver 一体机。

这是我目前所做的：

import argparse
import os
import sys
import unittest


def fixup_paths(path):
    """Adds GAE SDK path to system path and appends it to the google path
    if that already exists."""
    try:
        import google
        google.__path__.append("{0}/google".format(path))
    except ImportError:
        pass

    sys.path.insert(0, path)


def main(sdk_path, test_path, test_pattern):
    # If the SDK path points to a Google Cloud SDK installation
    # then we should alter it to point to the GAE platform location.
    if os.path.exists(os.path.join(sdk_path, 'platform/google_appengine')):
        sdk_path = os.path.join(sdk_path, 'platform/google_appengine')

    # Make sure google.appengine.* modules are importable.
    fixup_paths(sdk_path)

    # Make sure all bundled third-party packages are available.
    import dev_appserver
    dev_appserver.fix_sys_path()

    # Fix google shits
    from google.appengine.tools.devappserver2 import devappserver2

    # Start the devappserver
    server_instance = devappserver2.DevelopmentServer()
    server_instance.start()

    # Discover and run tests.
    suite = unittest.loader.TestLoader().discover(test_path, test_pattern)
    suite_result = unittest.TextTestRunner(verbosity=2).run(suite)
    server_instance.stop()
    return suite_result


if __name__ == '__main__':
    parser = argparse.ArgumentParser(
        description=__doc__,
        formatter_class=argparse.RawDescriptionHelpFormatter)
    parser.add_argument(
        'sdk_path',
        help='The path to the Google App Engine SDK or the Google Cloud SDK.')
    parser.add_argument(
        '--test-path',
        help='The path to look for tests, defaults to the current directory.',
        default=os.getcwd())
    parser.add_argument(
        '--test-pattern',
        help='The file pattern for test modules, defaults to *_test.py.',
        default='test_*.py')

    args = parser.parse_args()

    result = main(args.sdk_path, args.test_path, args.test_pattern)

    if not result.wasSuccessful():
        sys.exit(1)

但是我遇到了一个奇怪的导入错误。

我一直在搜索 Github，但找不到任何东西：

Traceback (most recent call last):
  File "runner.py", line 65, in <module>
    result = main(args.sdk_path, args.test_path, args.test_pattern)
  File "runner.py", line 34, in main

    from six.moves.urllib.request import parse_http_list, parse_keqv_list
ImportError: cannot import name parse_http_list

我不知道如何修复那个导入问题:(

Answer 1

该错误表示您安装的软件包六不包含parse_http_list。尝试升级六个包：

pip install six==1.14.0

可能是父包然后抛出错误，然后也升级该包。
