unittest on GAE has been a challenge for us as well. right now we trigger
our unittests via a controller run in the GAE dev server. it's not pretty,
but it mostly works and has the proper GAE env setup. I'd love to figure
out a cleaner way to make this happen.
here's the controller that we use to run the unittests:
def unittests():
"""
Admin page from which the unit tests can be run
"""
import os
from os.path import isfile, join
import sys
import glob
import logging
#get a list of the modules to test, and make it nice and readable
cdir = os.path.join('applications', request.application, 'tests')
if not os.path.isdir(cdir):
die("applications/%s/tests is not a directory"%request.application)
# Get the files in the /tests directory
onlyfiles = [ f for f in os.listdir(cdir) if isfile(join(cdir,f)) ]
# Strip __init__.py
onlyfiles.remove('__init__.py')
# Name them nicely, for the javascript
correctly_named_files = [ f[:-3] for f in onlyfiles if f[-3:] == '.py']
return dict(
filename_list=correctly_named_files
)
def run_one_test():
"""Controller that ajax POSTs too from the unittest page to
get the result of one unit test in html form.
Returns this result as a string
"""
import os
import sys
import cStringIO
from gluon.shell import env
from google.appengine.api import namespace_manager
#save stdout so we can capture data and reset it.
stdout = sys.stdout
stderr = sys.stderr
#get a list of the modules to test
test_file = os.path.join('applications', request.application, 'tests/',
'%s.py'%request.args[0])
html = ''
namespace_manager.set_namespace('myapp_test')
globs = env(request.application, c='default', f='index',
import_models=True, extra_request={'test_db':True})
sys.stdout = cStringIO.StringIO()
execfile(test_file, globs)
report = sys.stdout.getvalue().strip()
if report.find('FAIL') >= 0:
html += '<h3 class="failed">FAILED</h3>\n'
html += CODE(report, language='web2py', \
link='/examples/global/vars/').xml()
else:
html += '<h3 class="passed">PASSED</h3>\n'
sys.stdout = stdout
return html
So then we launch GAE dev server, and visit our tests/unittests
controller. from there we select a test to run and it is run in the GAE
environment. note that we set a different GAE namespace for running tests
in a clean DB. We found that executing in a running controller was easier
to setup the GAE environment properly then to get all the needed WSGI vars
in the shell.
