angular-scroll-animate/bower_components/jasmine/spec/core/QueueSpec.js

An Angular.js directive which allows you to perform any javascript actions (in the controller, or on the element) when an element is scrolled into, or out of, the users viewport, without any other dependencies.

describe("jasmine.Queue", function() {
  it("should not call itself recursively, so we don't get stack overflow errors", function() {
    var queue = new jasmine.Queue(new jasmine.Env());
    queue.add(new jasmine.Block(null, function() {}));
    queue.add(new jasmine.Block(null, function() {}));
    queue.add(new jasmine.Block(null, function() {}));
    queue.add(new jasmine.Block(null, function() {}));

    queue.next_ = function() {
      nestCount++;
      if (nestCount > maxNestCount) maxNestCount = nestCount;

      nestCount--;
