Request: request(url, function(error, response, body) 方法的单元测试用例

创建于 2016-04-18 · 3评论 · 资料来源: request/request

大家好，
在我的大多数文件中，我使用了以下方法 -

var request = require('request');
request(url, function(error, response, body) {
    if (!error && response.statusCode === 200) {

我如何在单元测试中存根这个方法？

已经尝试过 sinon.stub(request)，但这没有帮助。

Help (please use Stackoverflow) stale

尝试proxyquire ：

var proxyquire = require('proxyquire');
var requestSpy = jasmine.createSpy();
var myFile = proxyquire('../../file/that/requires/request', {
    request: requestSpy,
});
describe('the test', function() {
    it('should use the mock', function() {
        myFile.makeARequest();
        expect(requestSpy).toHaveBeenCalledWith(jasmine.objectContaining({
            headers: jasmine.objectContaining({
                Accept: 'application/json',
            }),
            method: 'GET',
        }), jasmine.any(Function));
    });
});

示例： http :

或者模拟需要

var mock = require('mock-require');
var requestSpy = jasmine.createSpy();
mock('request', requestSpy);
var myFile = require('../../file/that/requires/request');
describe('the test', function() {
    it('should use the mock', function() {
        myFile.makeARequest();
        expect(requestSpy).toHaveBeenCalled();
        // and you should be able to invoke the callback also, e.g.
        // var callback = requestSpy.calls.first().args[1];
        // expect(callback(/* vars */))...
    });
});

@simov已经尝试过，但找不到它，有人已经遇到过这个问题吗？
