我跟着这个question来测试路由器。我的路由器是非常简单的:用茉莉花和sinon测试骨干路由器。无法调用pushState。
App.Router = Backbone.Router.extend({
routes:{
"": "index",
"help": "help"
},
help: function() {/* not really needed */ },
index: function(){
// does something
}
});
这是什么都要用茉莉花与兴农测试的apptempted翻译:
it('triggers the "index" route', function() {
var router = new App.Router();
Backbone.history.start();
//Not calling navigate it's a problem
router.navigate('help', {
trigger : true, replace: true
});
var index = sinon.spy(router, 'index');
var spyHasPS = sinon.spy(function(
data, title, url) {
expect(url).toEqual('/');
router.index();
});
var spyNoPS = sinon.spy(function(loc, frag) {
expect(frag).toEqual('');
router.index();
});
if (Backbone.history._hasPushState) {
pushStateSpy = sinon.stub(window.history, 'pushState', spyHasPS);
// window.history.pushState();
} else if (Backbone.history._wantsHashChange) {
pushStateSpy = sinon.stub(Backbone.history, '_updateHash', spyNoPS);
//Backbone.history._updateHash(window.location, '');
}
router.navigate('', {
trigger : true, replace: true
});
expect(pushStateSpy.called).toBe(true);
expect(index.called).toBe(true);
});
这个测试工作,但我能做到,因为我导航先上“帮帮我”。 “帮助”只是我为了通过考试而创建的,但原始问题没有做到,而且正在通过。我做错什么了吗?我也跑了测试,但我得到的错误是:
Expected spy _updateHash to have been called. Error: Expected spy
_updateHash to have been called.
at null.<anonymous> (/src/test/js/spec/wfcRouter.spec.js:65:32) Expected spy index to have been called.
我相信“的问题”是在导航功能。在navigate: function(fragment, options)
某一点上,我们有这样的控制:
fragment = this.getFragment(fragment || '');
if (this.fragment === fragment) return;
所以...它是有意义的测试pushState的时候,你只需要一个路线(记住我说的“帮助”只是为了让这个测试通过所以我不需要它)?如果确实有道理,我该如何实现这个测试?
