Needle is a tool for testing your CSS with [Selenium](http://seleniumhq.org/) and [nose](http://somethingaboutorange.com/mrl/projects/nose/).
It checks that CSS renders correctly by taking screenshots of portions of a website and comparing them against known good screenshots. It also provides tools for testing calculated CSS values and the position of HTML elements.
Example
This is what a Needle test case looks like:
from needle.cases import NeedleTestCase
- class BBCNewsTest(NeedleTestCase):
- def test_masthead(self):
self.driver.get(’http://www.bbc.co.uk/news/’) self.assertScreenshot(‘#blq-mast’, ‘bbc-masthead’)
This example checks for regressions in the appearance of the BBC’s masthead.
