Not a silly question at all! Yes, I'm exiting the context. My base test
code looks like this:
import requests
import unittest
import webapp2
from google.cloud import ndb
from test._testhelper import TestHelper
NDB_CLIENT = ndb.Client(project='tilegames2')
NDB_CLIENT.host = 'localhost:8089'
NDB_CLIENT.secure = False
class MyTestCase(unittest.TestCase):
def setUp(self):
self.testapp = webapp2.WSGIApplication([])
self.testHelper = TestHelper()
# clear datastore
requests.post('http://localhost:8089/reset')
self.ndb_context = NDB_CLIENT.context()
self.ndb_context.__enter__()
def tearDown(self):
self.ndb_context.__exit__(None, None, None)
