Trigger only works if it's the first test on the spec

[andregumieri]

It's a weird behaviour that is happening on my tests. First, I confess that i'm new on it, but i've made my researches and didn't find anything that helps me.

Depending on the order I execute the tests, it passes or fails. But, as I see, one shouldn't conflict with another.

My stack:

• an already compiled script with browserify
• karma
• jasmine + jasmine-jquery (of course).

I've created the follow spec. Really simple. It shoud verify if a function is defined and then, if a class is added to a element when the event is triggered:

describe('Menu', function() {
    beforeEach(function() {
        jasmine.getFixtures().clearCache()

        var f = jasmine.getFixtures();
        f.fixturesPath = 'base/test/fixtures';
        f.load('menu.html');
        $.holdReady(false);
    });

    afterEach(function() {
        var f = jasmine.getFixtures();
        f.cleanUp();
        f.clearCache();
    });

    it('should be defined', function() {
        expect(window.app.components.menu.init).toBeDefined()
    });

    it('should show the submenu on hover', function() {
        var $a = $(".sub").eq(0).parent().children("a");
        $a.trigger("mouseenter");
        expect($(".sub").eq(0)).toBeMatchedBy('.show');
    });
});

It fails:

04 12 2015 13:02:23.841:INFO [watcher]: Changed file "/Users/admin/teste-dev/karma-teste-boilerplate/test/menu-spec.js".

Now, the weird part: If I put the trigger validation before the defined, it works:

describe('Menu', function() {
    beforeEach(function() {
        jasmine.getFixtures().clearCache()

        var f = jasmine.getFixtures();
        f.fixturesPath = 'base/test/fixtures';
        f.load('menu.html');
        $.holdReady(false);
    });

    afterEach(function() {
        var f = jasmine.getFixtures();
        f.cleanUp();
        f.clearCache();
    });

    it('should show the submenu on hover', function() {
        var $a = $(".sub").eq(0).parent().children("a");
        $a.trigger("mouseenter");
        expect($(".sub").eq(0)).toBeMatchedBy('.show');
    });

    it('should be defined', function() {
        expect(window.app.components.menu.init).toBeDefined()
    });
});

It passes:

I've tried the following without success:

• Use spyOn on the mouseenter event
• Use another matches, as 'toHaveClass' expect($(".sub").eq(0)).toHaveClass('show'); and toBe expect($(".sub").eq(0).hasClass('show')).toBe(true);
• Use the script without browserify
• Use browserify plugin on karma
• cleanUp() on afterEach, on afterAll and even don't cleanUp at all
• The same to setup the fixture: tried on beforeEach and beforeAll
