Backbone.js BackboneJS使用jasmine测试是否传递参数以获取

我有一个主干集合，需要将一些参数传递给.fetch（{data:{gender:'male'}）。有没有办法用jasmine测试参数是否通过

提前感谢

您可以使用下面示例中的方法来实现这一点。 请注意，，下面的代码将截获获取调用并返回，调用将不会到达服务器。如果希望进行服务器端仿真，则需要使用Sinon或其他类似方法

    describe("People collection" function() {
        var people = Backbone.Collection.extend({
            // ...
        });

        function searchPeople(people, data ) {
            people.fetch(data);
        }

        it("must verify the fetch parameters!", function(){
            var param = {data : {gender : 'male'}};
            // Set up the spy.
            spyOn(people, 'fetch').andReturn(); // Warning: this makes the call synchronous, Fetch actually won't go through!

            // Now perform the operation that would invoke Collection.fetch.
            searchPeople(people, param);

            expect(people.fetch).toHaveBeenCalled();            // Verifies the fetch was actually called.
            expect(people.fetch).toHaveBeenCalledWith(param);   // Verifies that the fetch was called with specified param.

        });
    });
