为 google 云端点编写测试用例 API 编写在 django 之上
Writing Testcases for google cloud endpoints API written on top of django
我在我的 Django 应用程序上使用 google 云端点来提供 RESTful 服务。所有 API 服务都运行良好。现在，是时候编写测试用例了。所以我写了这个。
TestPOIList.py
import unittest
from django.test import TestCase
import endpoints
import webtest
from google.appengine.ext import testbed
from .queries import CategoryQuery
from .queries import PointOfInterestQuery
from .models import PointOfInterest
from .api.internal.point_of_interest import PointOfInterests
class Test(TestCase):
def setUp(self):
self.testbed = testbed.Testbed()
self.testbed.setup_env(current_version_id='testbed.version')
self.testbed.activate()
self.testbed.init_all_stubs()
self.category_a = CategoryQuery.create_category_by_name('Museums')
self.poi = PointOfInterestQuery.create_new_poi(name='bhavan', category=self.category_a,
place='hdgf', phone='3454545', email='dsg@jhgs.com'
)
app = endpoints.api_server([PointOfInterests], restricted=False)
self.testapp = webtest.TestApp(app)
def tearDown(self):
self.testbed.deactivate()
# Test the handler.
def test_should_return_list_of_pois(self):
msg = {}
resp = self.testapp.post_json('/_ah/spi/PointOfInterests.get_list', msg, status='*')
self.assertEqual(resp.status_code, 200)
self.assertEqual(resp.json['pois']['name'], 'Saravan bhavan')
我尝试 运行 将上述代码与 python manage.py test 、python manage.py test appname 结合使用。但是不行。
我也试过django-nose。它甚至无法测试单个测试用例。在 运行ning python manage.py test 之后显示的输出是，
----------------------------------------------------------------------
Ran 0 tests in 0.000s
OK
Destroying test database for alias 'default'...
所以它未能 运行 我的第一个测试用例。请给些建议。
编辑：
将文件名更改为testpoilist 找到测试用例，但无法导入appengine 相关模块。并导致许多 import 错误。所以我尝试了 运行ning nosetests 但它显示，

看来我快接近了。 PYTHONPATH 变量显示 google_appengine sdk 路径。
在appengine_config.py中将vendor.add('lib')改为vendor.add(os.path.join(os.path.dirname(os.path.realpath(__file__)), 'lib'))。执行测试的路径与 lib 无关，因此您会看到该错误。不要忘记导入 os.
我已通过将项目的 lib 文件夹附加到系统路径变量来解决此问题。
所以您的 manage.py 文件的一部分应该类似于
if __name__ == "__main__":
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mysite.settings")
sys.path.append(sys.path[0] + os.path.sep + 'lib')
然后运行通过django测试。不要做 nosetest.
python manage.py test
请注意，您的测试文件的名称应以 test 开头，以便 django 将其视为测试文件。我的一个测试文件看起来像，
