Question

我有我的源文件，我为其编写了

的测试用例

var debug = require('debug')('kc-feed:source:fb');
var request = require('request');
var config = require('../../config').root;


exports.source = function fetchFeed (callback) {
  var params = {
      headers: {'content-type' : 'application/jsons'},
      url: config.host + "v1/social/fb/sync_feed", 
      method: 'GET'
  };

  request(params, function(err, body, response) {
    if(err) {
      callback(err);
    }
    else {
      var raw_data = JSON.parse(response);
      callback(null, raw_data);
    }
  });
};

这是我的摩卡测试用例

var chai = require('chai'),
    expect = chai.expect,
    app = require('../app'),
    rewire = require('rewire'),
    fbfeed = rewire('../src/feed/source/fb_feed'),
    supertest = require('supertest'),
    sinon = require('sinon'),
    nock = require('nock');

describe('test cases for fb feed file', function() {
    var callback;
    beforeEach(function(){
        callback = sinon.spy();     
    });

    after(function(){
        nock.cleanAll();
    });

    it('callback should be called with the response', function(done) {
        nock('http://localhost:3000/')
            .get('/v1/social/fb/sync_feed') 
            .reply(200, {});
            callback = sinon.spy();
        fbfeed.source(callback);
        sinon.assert.calledOnce(callback);
        done();
    }); 

    it('callback should be called with the error', function(done) {
        nock('http://localhost:3000/')
            .get('/v1/social/fb/sync_feed') 
            .replyWithError(new Error('err'));
        fbfeed.source(callback);
        sinon.assert.calledOnce(callback);
        done();
    });

我的测试用例都失败了，因为它说回调被调用了0次。但总是调用回调。请帮忙。

看起来请求仍在异步执行（我无法明确说明在使用nock时是否预期这样做），所以你不能使用这样的间谍。

提供常规回调：

fbfeed.source(function(err, raw_data) {
  ...make your assertions...
  done();
});

sinon间谍作为回调未被召唤
