Automating everything

Test automation was never so easy without Gulp. Gulp is an open source JavaScript library that provides efficient build creation processes and serves as a task runner. We will use Gulp to automate our unit tests by a single command in terminal.

npm install gulp-cli -g
npm install gulp --save-dev
touch test/gulpfile.js
gulp --help

Note that you may require root access to install the global package of gulp-cli. Use sudo in such cases, for example, sudo npm install gulp-cli -g. We used --save-dev to install Gulp locally and save it as a development dependency in our package.json.

Further, we created a Gulp file in the test directory. Now, to test the directory of our app and make sure that we have the following file structure:

Once we've installed the required packages and created a Gulp file, let's start writing some code, as follows:

var gulp = require('gulp');
gulp.task('default', function(...
