Using Test Classes, Test Title and Link [ID:601] (4/5)

in series: Robust and Reliable Web Sites with twill and nosetests

(Showmedo is undergoing major changes. To report any problems viewing the videos please email us and include browser and OS specifics. Cheers - Kyran.)

For our third test we write a class-based test and look at the setUp and tearDown methods. During the test we confirm that our page's title looks right and that a link exists.

We then follow the link and confirm that we end up on the correct page (in case the website was using a redirect - though our's isn't).

I also show another way of running a unit test by using the format 'nosetests' which allows us to drill into just 1 method inside a class inside a file.

from twill.commands import *

# usage examples:
# nosetests - try all tests that nosetests can find
# nosetests - call all tests in the file
# nosetests
# nosetests

# twill API reference

def test_homepage_OK():
    "test we can get to the homepage"
    # 200
    http_code = b.result.get_http_code()    
    print "http_code", http_code
    assert http_code == 200
def test_404():
    "test that a bad url generates a 404 error"
    # 404 OK
    http_code = b.result.get_http_code()    
    print http_code
    assert http_code == 404

class Tests(object):
    def setUp(self):
        print "setUp"
        self.b = get_browser()
    def tearDown(self):
        print "tearDown"
    def test_title(self):
        "test that our title contains the right text"
        http_code = self.b.result.get_http_code()    
        assert http_code == 200
        title = self.b.get_title()
        print title
        assert "Learning Python" in title

    def test_link(self):
        "test we can find an expected link and that we follow it to the right destination"
        # find the first link to
        link = self.b.find_link('/videos/python')
        print link
        #Link(base_url='', url='/videos/python', 
        #text='Python', ta [('href', '/videos/python')])
        # follow the link
        current_url = self.b.get_url()
        print current_url
        assert current_url == ""

Educating the Open-source Community With Showmedo

Although as important as the software it supports, education and documentation are relatively neglected in the Open-source world. Coders love to code, and explaining how best to use or improve the software tends to be deferred or even sidelined.

At Showmedo we believe the community can play a vital role here and also say thanks for the tools and software that make our lives easier. If you have a piece of software you love or a programming langugage you are enthusiastic about, why not make a screencast showing others how to use it? All the stuff you wish you'd been told, the tips, tricks, insights that would have saved you time and frustration.

Screencasting is easier than you think, and we're happy to help you. You can emailus for advice or just use some of the how-to screencasts on the site. This screencasting learning-pathis a good place to start.

Kudos and Thanks for Ian
