You can hand-write the data in the responseText attribute of the $.mockjax call:

$.mockjax({
  url: '/products',
  type: 'GET',
  dataType: 'json',
  responseTime: 750,
  responseText: ['Here I can fake the response']
});

You can use a function to generate the mock data:

$.mockjax({
  url: '/products',
  type: 'GET',
  dataType: 'json',
  responseTime: 750,
  response: function(settings) {
    var fake = 'We fake the url:'+settings.url;
    this.responseText = fake;
  }
});

You can use a library that generates complex and random data in the response.

This third option can be performed with a library called mockJSON. You can download it from the GitHub repository at https://github.com/mennovanslooten/mockJSON.

This library allows you to generate data templates to create random data. This helps you to keep your fake data more realistic. You can see on...
