 Other than that, we try to use as less Karma plugins as possible because they often duplicate process we already have inside Gulp. For sake of coherence and stability we're searching for a process centralized in Gulp and not duplicated in Karma or other tools like perhaps Webpack.
 
+## End to end tests
+
+The generator provides end to end testing using [Protractor](https://angular.github.io/protractor/#/). By default, Protractor uses the Jasmine test framework for its testing interface. There is an option to change the testing framework to [Cucumber](https://cucumber.io/), a BBD testing framework that uses human readable feature tests to drive assertions.
+
+When the Cucumber options is selected, the [Chai](http://chaijs.com/) library loaded for assertions in your end-to-end tests.
+
 ## Optimization process
 
 The central piece of the optimization process is the use of the [gulp-useref](https://github.com/jonkemp/gulp-useref). Its task is to concat files and rewriting the `index.html` file to points on the concat versions of the files. All works with HTML comments block starting with `<!-- build:(...) ->` and ending with `<!-- endbuild -->`.
