使用 Mocha for NodeJS 测试表单数据

Question

我正在尝试为发送表单数据并检查响应是否正常 (200) 的 nodejs 编写 mocha 测试，并且 res.body 具有一些属性，但是 测试失败 并且我不知道原因。增加 timout 没有帮助，当我使用 AdvancedRESTclient chrome 扩展和 Payload 部分中的表单数据时，它完美地工作！ .type('form') 应该是超级代理语法

var should = require('should'),
    assert = require('assert'),
    request = require('supertest'),
    superagent = require('superagent');

        describe('Data', function () {

            it('should return status OK (200)', function(done) {
                this.timeout(20000);
                request.post('http://xxx:3000/xxx/xxx')
                    .type('form')
                    .send({startDate:"2015-03-08",endDate:"2015-03-24",timeLapse:"day"})
                    .end(function(err, res) {
                        if (err) {
                            throw err;
                        }
                        assert.ok(res);
                        assert.ok(res.body);
                        assert.equal(res.status, 200);
                        res.body.should.have.property('trial');
                        done();
            });
        });

错误是：

试试这个：

var should = require('should'),
    assert = require('assert'),
    request = require('supertest')('http://xxx:3000'),
    superagent = require('superagent');

        describe('Data', function () {

            it('should return status OK (200)', function(done) {

                request.post('/xxx/xxx')
                    .type('form')
                    .send({startDate:"2015-03-08",endDate:"2015-03-24",timeLapse:"day"})
                    .end(function(err, res) {
                        if (err) {
                            throw err;
                        }
                        assert.ok(res);
                        assert.ok(res.body);
                        assert.equal(res.status, 200);
                        res.body.should.have.property('trial');
                        done();
            });
        });
