I do this all the time. The main idea is documented here: https://github.com/renzon/tekton/wiki https://github.com/renzon/tekton/wiki You can see tests all over my repos starting with prefix "gae".Here you have a example of a app that I build to automate form validation: https://github.com/renzon/gaeforms/blob/master/test/ndb/form_tests.py https://github.com/renzon/gaeforms/blob/master/test/ndb/form...
