homophony Description

Django and zc.testbrowser integration homophony is a software that provides zc.testbrowser integration for Django; zc.testbrowser is a lot more robust than the default functional testing client that comes with Django.See the introduction to zc.testbrowser for a better understanding of how powerful it is.Using homophonyFirst of all, you need to have homophony installed; for your convenience, recent versions should be available from PyPI.Let's say you're working on an application called foobar; the tests for this application are located in foobar/tests.py.Unit testsUse this as a starting point for foobar/tests.py:from homophony import BrowserTestCase, Browserclass FoobarTestCase(BrowserTestCase): def testHome(self): browser = Browser() browser.open('http://testserver') browser.getControl(name='first_name').value = 'Jim' browser.getForm().submit() self.assertEquals(browser.url, 'http://testserver/hello') self.assertEquals(browser.title, 'Hello Jim')Bear in mind that implementing custom setUp and tearDown methods should involve calling those defined in BrowserTestCase.DoctestsIf you prefer doctests over unit tests (as we do!), use the following as a base for foobar/tests.py:from homophony import DocFileSuitedef suite(): return DocFileSuite('tests.txt')And here is an example foobar/tests.txt file:The website welcomes its visitors with a form: >>> browser = Browser() >>> browser.open('http://testserver') >>> browser.getControl(name='first_name').value = 'Jim' >>> browser.getForm().submit()When a name is given, it echoes back with an informal greeting: >>> browser.title 'Hello Jim' >>> print browser.contents < !DOCTYPE html > ... < h1 >Hello Jim< /h1 > ...And there is a link to go back: >>> browser.getLink('Go back').click() >>> browser.title 'Home'HelpersThere are some useful helpers on the browser class. You can run XPath queries on HTML documents using queryHTML, like this: >>> browser.queryHTML('//h1') < h1 >Hello Jim< /h1 >When debugging tests, it is sometimes handy to open a browser at a particular point in the test. You can accomplish that by invoking serve: >>> browser.serve()This command will start an HTTP server and open a web browser with live access to your application. Use Ctrl-C to stop the server and continue running tests.There is a known issue that the mini-webserver does not serve static files, so your browser may not be able to access Javascript or CSS used by your app.Example applicationThere is an example Django application in the source distribution. Let's run the tests:wormhole:example admp$ ./manage.py test -v 2 websiteCreating test database...Creating table auth_permissionCreating table auth_groupCreating table auth_userCreating table auth_messageCreating table django_content_typeCreating table django_sessionCreating table django_siteInstalling index for auth.Permission modelInstalling index for auth.Message model...testHome (example.website.tests.FoobarTestCase) ... okDoctest: tests.txt ... ok----------------------------------------------------------------------Ran 2 tests in 0.102sOKDestroying test database...The -v 2 parameter is there to get the list of tests printed, and is otherwise unnecessary.For learning purposes, try to break the tests and witness the details in the output of the test runner.How does it work?Custom hooks are installed for urllib to pass all requests for http://testserver to a subclass of WSGIHandler (which exposes Django applications through WSGI). The real heavy lifting is performed by wsgi_intercept. Requirements: · Python
