使用Jasmine监视Backbone.js路由调用

const MyRouter = Backbone.Router.extend({
  routes: {
    "home": "home",
    "about": "about"
  },

  home: function() {
    // 路由逻辑
  },

  about: function() {
    // 路由逻辑
  }
});

describe("MyRouter", function() {
  let router;

  beforeEach(function() {
    router = new MyRouter();
    spyOn(router, "home");
    spyOn(router, "about");
  });

  it("should call home route", function() {
    router.navigate("home", { trigger: true });
    expect(router.home).toHaveBeenCalled();
  });

  it("should call about route", function() {
    router.navigate("about", { trigger: true });
    expect(router.about).toHaveBeenCalled();
  });
});
