在django之上为google云端点API编写测试用例
在django之上为google云端点API编写测试用例
提问于 2016-03-04 13:41:11
我在我的django应用程序上使用来提供RESTful服务。所有的API服务都运行得很好。现在是写测试用例的时候了。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')我试着用python manage.py test，python manage.py test appname运行上面的代码。但这行不通。
我还试过django-nose。它甚至连一个测试用例都无法测试。运行python manage.py test后显示的输出是，
----------------------------------------------------------------------
Ran 0 tests in 0.000s
OK
Destroying test database for alias 'default'...所以它没能运行我的第一个测试案例。请给我一些建议。
编辑：
将文件名更改为testpoilist可以找到测试用例，但它无法导入与应用程序引擎相关的模块。并导致了许多import错误。所以我试着运行nosetests，但是它显示，

通过将项目的lib文件夹附加到系统路径变量中，我设法解决了这个问题。
所以manage.py文件的一部分应该是，
if __name__ == "__main__":
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mysite.settings")
sys.path.append(sys.path[0] + os.path.sep + 'lib')然后通过django运行测试。不要做nosetest。
python manage.py test注意，您的测试文件应该有一个以test开头的名称，这样django就会把它当作一个测试文件。我的一个测试文件看起来像，
import unittest
from django.test import TestCase
import endpoints
import webtest
from google.appengine.ext import testbed
from project.queries import CategoryQuery
from project.api.internal.categories import Categories
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')
app = endpoints.api_server([Categories], 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/Categories.get_list', msg, status='*')
self.assertEqual(resp.status_code, 200)
self.assertEqual(resp.json['categories'][0]['name'], 'Museums')Stack Overflow用户

在appengine_config.py中，将vendor.add('lib')更改为vendor.add(os.path.join(os.path.dirname(os.path.realpath(__file__)), 'lib'))。您的测试正在执行的路径不是相对于lib的，因此您将看到该错误。不要忘记导入os。
