Custom boot

If you want to customize your jasmine environment you can customize your boot.js file.

The core of boot.js should stay the same, but you can add new things to the interface or configure things by changing this file.

 
(function() {

  window.jasmine = jasmineRequire.core(jasmineRequire);

  jasmineRequire.html(jasmine);

  var env = jasmine.getEnv();

Customizing the interface

Once the core jasmine interface has been loaded, you can add new functions or rewrite existing functions.

 
  var jasmineInterface = jasmineRequire.interface(jasmine, env);

Here, we're adding some aliases so before is the same as beforeEach

 
  jasmineInterface.before = jasmineInterface.beforeEach;

after is the same as afterEach

 
  jasmineInterface.after = jasmineInterface.afterEach;

and context is the same as describe

 
  jasmineInterface.context = jasmineInterface.describe;

  if (typeof window == "undefined" && typeof exports == "object") {
    extend(exports, jasmineInterface);
  } else {
    extend(window, jasmineInterface);
  }

Adding a custom reporter

You can also add your own reporter either in addition to or in place of the jsApiReporter and htmlReporter

 
  env.addReporter(jasmineInterface.jsApiReporter);

You can also customize how specs are filtered from the current run by changing the env.specFilter function

Alternately, specs to be run may also be specified after the tests have been parsed by passing an array of suite or spec IDs to the execute function. These IDs can be gleaned by traversing the tree of parsed tests accessible via env.topSuite().

 
  var specFilter = new jasmine.HtmlSpecFilter({
    filterString: function() { return queryString.getParam("spec"); }
  });

  env.specFilter = function(spec) {
    return specFilter.matches(spec.getFullName());
  };

  window.setTimeout = window.setTimeout;
  window.setInterval = window.setInterval;
  window.clearTimeout = window.clearTimeout;
  window.clearInterval = window.clearInterval;

By default, Jasmine will begin execution when the onload event is triggered in the browser. Replace this portion, if you want to wait for something else before calling execute

 
  var currentWindowOnload = window.onload;

  window.onload = function() {
    if (currentWindowOnload) {
      currentWindowOnload();
    }
    env.execute(env.topSuite().id);
  };

Helper function to add the Jasmine public interface to the correct object.

 
  function extend(destination, source) {
    for (var property in source) destination[property] = source[property];
    return destination;
  }

}());
