Needle

Build Status

Needle is a tool for testing visuals with Selenium and nose.

It checks that visuals (CSS/fonts/images/SVG/etc.) render 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.

Documentation

Full documentation available on Read the Docs.

If you'd like to build the documentation yourself, first install sphinx:

pip install sphinx

Then run:

cd docs
make html

The documentation will then be available browsable from docs/_build/index.html.
