How to perform Automated Unit Testing with JavaScript?

To perform unit testing in JavaScript, use Unit.js. It is a cross-platform open-source unit testing framework.

Example

Let’s say the following in your test code −

var example = ‘Welcome’;
test.string(example)
.isEqualTo(‘Welcome’);

The function demo() displays a suit of tests, whereas demo1() is an individual test specification,

demo('Welcome’, function() {
   demo1('Welcome to the website', function() {
      var example = ‘Welcome’;
      test.string(example)
      .isEqualTo(‘Welcome’);
   });
});
