I love atomic design with patternlab. But in combination with gemini, which provides utility for css regression tests, it's an awesome workflow for working on large scale projects, redesigns and especially css refactoring.
The idea behind this project is to generate the test cases automatically from the styleguide of patternlab.
This is a Node.js library. A soon as you have Node.js installed, just install it via npm:
$ npm install patternlab-to-gemini --save-dev
To start using patternlab-to-gemini you have to have a json config file. See Configuration for detail info.
As soon as you have you config file ready, you can generate your tests with the following command:
$ ./node_modules/.bin/patternlab-to-gemini -c path/to/your/configfile.json
You may also use --debug or -d to get debug output.
