needle 0.2.0

Automated testing for your CSS.

Latest Version: 0.5.0

[![Build Status](](

Needle is a tool for testing your CSS with [Selenium]( and [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.


This is what a Needle test case looks like:

from needle.cases import NeedleTestCase

class BBCNewsTest(NeedleTestCase):
def test_masthead(self):
self.driver.get(‘’) self.assertScreenshot(‘#blq-mast’, ‘bbc-masthead’)

This example checks for regressions in the appearance of the BBC’s masthead.
