Can protractor tests be run in a random order?

问题:

I'm trying to enforce independence between protractor tests within a spec. To detect whether or not tests are depending on a state introduced by an previous test, I would like to run those tests in random order.

Is there a way to tell protractor the order of tests can be randomized?

I found a feature request for Jasmine at pivotaltracker

回答1:

As of 10/10/17, it's possible to set a setting in the protractor.conf.js JasmineNodeOpts to run specs in semi-random order when using Jasmine, no code needed.

In your protract.conf.js file add the following json block:

  jasmineNodeOpts?: {
    ...
    /**
     * If true, run specs in semi-random order
     */
    random?: boolean,
    ...
  };

You could execute the specs in a random order by shuffling them at the end of the suite:

var shuffle = function (items) {
  var item, ii;      
  for(var i = 0; i < items.length; i++){
    ii = (Math.random() * items.length) | 0;
    item = items[i];
    items[i] = items[ii];
    items[ii] = item;
  }
}

describe('Suite', function() {

  it("should a", function () {
      console.log("execute a");
  });

  it("should b", function () {
      console.log("execute b");
  });

  it("should c", function () {
      console.log("execute c");
  });

  shuffle(this.children);    // shuffle the specs

});
