karma-git-diff

A Karma plugin to export the list of git diff to the JavaScript tests.

How-to

Install the karma-git-diff plugin:

npm install --save-dev karma-git-diff

Then add it to your karma.conf.js and configure it properly:

modules.exports = function(config) {
  config.set({
    frameworks: ['jasmine', 'git-diff'],
    gitDiffConfig: {
      ref: 'origin/master'
    }
  });
};

In your Javascript in Karma, there will now be a window.__gitdiff__ that is an array of files that changed.

> console.log(window.__gitdiff__);
[ "karma.conf.js", "package.json", "test/root.js" ]
