你今天如何用茉莉花测试这个?您是要浏览每个更改还是尝试使用 jasmine-phantom-node / jasmine-node 之类的命令行运行它?
一个示例可能如下所示。在下面的设置中,我正在测试一个视图,但相同的模拟/间谍想法适用于您上面的路由器示例。
require('static/script/vendor/filtersortpage.js');
require('static/script/app/person.js');
describe ("PersonApp.PersonView Tests", function(){
var sut, router, controller;
beforeEach(function(){
sut = PersonApp.PersonView.create();
router = new Object({send:function(){}});
controller = PersonApp.PersonController.create({});
controller.set("target", router);
sut.set("controller", controller);
});
it ("does not invoke send on router when username does not exist", function(){
var event = {'context': {'username':'', 'set': function(){}}};
var sendSpy = spyOn(router, 'send');
sut.addPerson(event);
expect(sendSpy).not.toHaveBeenCalledWith('addPerson', jasmine.any(String));
});
it ("invokes send on router with username when exists", function(){
var event = {'context': {'username':'foo', 'set': function(){}}};
var sendSpy = spyOn(router, 'send');
sut.addPerson(event);
expect(sendSpy).toHaveBeenCalledWith('addPerson', 'foo');
});
it ("does not invoke set context when username does not exist", function(){
var event = {'context': {'username':'', 'set': function(){}}};
var setSpy = spyOn(event.context, 'set');
sut.addPerson(event);
expect(setSpy).not.toHaveBeenCalledWith('username', jasmine.any(String));
});
it ("invokes set context to empty string when username exists", function(){
var event = {'context': {'username':'foo', 'set': function(){}}};
var setSpy = spyOn(event.context, 'set');
sut.addPerson(event);
expect(setSpy).toHaveBeenCalledWith('username', '');
});
});
如果您想在某些上下文中查看它,这里是一个真实项目中的茉莉花测试
这是被测视图(帮助理解上述茉莉花测试)
PersonApp.PersonView = Ember.View.extend({
templateName: 'person',
addPerson: function(event) {
var username = event.context.username;
if (username) {
this.get('controller.target').send('addPerson', username);
event.context.set('username', '');
}
}
});
