The plugin uses gets number of errors/warnings from W3C's Unified Validator.

Global Configuration


Project Configuration

For a project to use the Unicorn Validation plugin, you need to add it as a build step to your job:

Here you can specify:

Unicorn service URL - the w3c's url is the default one, but you can specify your own if you have custom unicorn service


Max number of errors/warnings for build to be stable/unstable - this is your threshold to decide if the build should be stable/unstable/failed ... currently these number are the same for every aspect of unicorn result (html, css, rss).

Plot Configuration

You can also get a pretty graph which shows you number of warnings/errors of previous builds. There a unicorn template for that to help you configure it.


- currently all the test are executed that the unicorn validator offers ... ability to choose which ones to execute
