needle 0.2.3

Automated testing for your CSS.

[](https://travis-ci.org/bfirsh/needle)

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.
