Testing in TurboGears

I finally got time to continue on my GTD application. I wrote unit tests for all controller methods.

My first idea was to include a mock framework so I wouldn’t need to execute external logic in my tests, but then I realized that would be overkill. I’m using an in-memory database (SQLite) and executing the whole application stack (except for javascript). All tests runs within 10 seconds, which is acceptable.

TurboGears includes Nose, which is a test discovery and running process for unittest. Typing “nosetests” on the command line runs all tests in the project.

I’ve decided to later use AJAX in my application, and a good way to test the whole stack including javascript is to test with Selenium. I’ll leave this for later.

It just works

I have never felt such a joy developing a web application. I get into flow more often. Things just work and I rarely show the ‘what the heck happened’-face.

baseTest.py:

from turbogears import testutil
from turbogtd.controllers import Root
from turbogtd import model
import cherrypy

cherrypy.root = Root()
cherrypy.config.update({"sqlalchemy.dburi" : "sqlite:///:memory:"})
cherrypy.config.update({'sessionFilter.on': True})

class BaseTest:
  def setUp(self):
    # a 'dummy' call to initialize the database
    testutil.create_request('/')
    model.create()
  def tearDown(self):
    model.drop()

test_project.py:

class TestProject(BaseTest):
  def test_create(self):
    testutil.create_request('/project/create?title=title&notes=notes')
    page = cherrypy.response.body[0]
    assert 'Project added' in page, "text not found. page: " +page
    project = Project.get(1)
    assert 'title' == project.title, "error in title: " +project.title
    assert 'notes' == project.notes, "error in notes: " +project.notes
