ExtJS 4.2.1模拟Ext.Ajax.request(ExtJS 4.2.1 mocking Ext.Ajax.request)

 对于使用jasmine的前端单元测试，我想在我的应用程序中模拟我的所有请求。 
 
 我已经实现了一个方法来模拟我的所有代理。 
 
proxy: appname.classes.proxy.ProxyNegotiator.getModelProxy("User")
 
 这个方法做的是这样的： 
 
getModelProxy: function(config) {
    var url = this.getUrl(config);

    if (this.getProxyType() == 'api') {
        return appname.classes.proxy.WebApiProxy.getModelProxy(url);
    } else if (this.getProxyType() == 'test') {
        return appname.classes.proxy.LocalTestProxy.getModelProxy(url);
    }
    return undefined;
}
 
 所以你可以想象，根据我的ProxyType配置，我得到web api代理或本地代理进行测试。 我现在已经覆盖了我的粗暴行动.. 
 
 不过，我还有另外一个问题要处理..我的应用程序中还有其他一些请求，如此（用户名的验证）： 
 
//check if Username is Valid
Ext.Ajax.request({
    url: '/api/User',
    method: 'GET',
    async: false,
    params: { id: user.get('Id'), username: user.get('UserName') },
    failure: function(response, opts) {
        myErrors.push({
            field: 'UserName',
            message: appname.locale.ErrorInvalidUsername
        });
    }
});
 
 我确实有一些麻烦嘲笑这个Ext.Ajax.request的东西......我已经在网上搜索过了，并没有找到任何好的解决方案。 什么是模拟此请求的最佳做法？ 我很高兴你能给我的每一个暗示和/或想法。 请帮忙！ 

For frontend unit testing with jasmine i want to mock all my requests in my application. 
 
I've already implemented a method to mock all my proxies.
 
proxy: appname.classes.proxy.ProxyNegotiator.getModelProxy("User")
 
and this method does something like this:
 
getModelProxy: function(config) {
    var url = this.getUrl(config);

    if (this.getProxyType() == 'api') {
        return appname.classes.proxy.WebApiProxy.getModelProxy(url);
    } else if (this.getProxyType() == 'test') {
        return appname.classes.proxy.LocalTestProxy.getModelProxy(url);
    }
    return undefined;
}
 
so you can imagine depending on my ProxyType configuration i get the web api proxy or the local proxy for testing. I do now have covered my crud operations..
 
Still, i do have another issue to deal with.. I do have some other requests in my application like this (validation of the username):
 
//check if Username is Valid
Ext.Ajax.request({
    url: '/api/User',
    method: 'GET',
    async: false,
    params: { id: user.get('Id'), username: user.get('UserName') },
    failure: function(response, opts) {
        myErrors.push({
            field: 'UserName',
            message: appname.locale.ErrorInvalidUsername
        });
    }
});
 
I do have some troubles with mocking this Ext.Ajax.request things... I've already searched in the web and did not find any nice solution for this. Whats best practice to mock this request? I am glad about every hint and/or idea u can give me. Please HELP!
