如何爲ng2單元測試模擬ng2-restangular？

Question

我試圖找到正確的方法來模擬ng2-restangular來測試我的ng2服務。

例如，對於服務方法：

get(id) { 
    return this.restangular.all('notes').get(id); 
}

import {BaseRequestOptions, Http} from "@angular/http"; 
import {MockBackend} from "@angular/http/testing"; 
import {RestangularHttp} from "../../src/ng2-restangular-http"; 

export const MockProviders = [ 
    BaseRequestOptions, 
    MockBackend, 
    { 
    provide: RestangularHttp, 
    useFactory: (http: Http) => { 
     return new RestangularHttp(http); 
    }, 
    deps: [Http] 
    }, 
    { 
    provide: Http, 
    useFactory: (backendInstance: MockBackend, defaultOptions: BaseRequestOptions) => { 
     return new Http(backendInstance, defaultOptions); 
    }, 
    deps: [MockBackend, BaseRequestOptions] 
    }, 
];
