ReferenceError:描述未定义NodeJs [英] ReferenceError: describe is not defined NodeJs

问题描述

我正在尝试定义一些端点并使用nodejs进行测试.在server.js中，我有:

I am trying to define some endpoints and do a test using nodejs. In server.js I have:

var express = require('express');
var func1 = require('./func1.js');
var port = 8080;
var server = express();

server.configure(function(){
  server.use(express.bodyParser());
});

server.post('/testend/', func1.testend);

和func1.js中的

    var testend = function(req, res) {
           serialPort.write("1", function(err, results) {
           serialPort.write("2" + "\n", function(err, results) {
           });
      });
   });
    exports.testend = testend;

现在在test.js中，我正在尝试使用此端点:

Now in test.js I am trying to use this endpoint:

var should = require('should');
var assert = require('assert');
var request = require('supertest');
var http = require('http');
var app = require('./../server.js');
var port = 8080;

describe('Account', function() {
        var url = "http://localhost:" + port.toString();
        it('test starts', function(done) {
                request(url).post('/testend/')
                // end handles the response
                .end(function(err, res) {
                        if (err) {
                                throw err;
                        }
                        res.body.error.should.type('string');
                        done();
                });
        });
});

但是当我运行node test.js时，出现此错误:

But when I run node test.js I am getting this error:

describe('Account', function() {
^

ReferenceError: describe is not defined

如何解决此问题?

推荐答案

假设您正在通过 mocha 进行测试，则必须运行使用mocha命令而不是node可执行文件进行测试.

Assuming you are testing via mocha, you have to run your tests using the mocha command instead of the node executable.

因此，如果您还没有这样做，请确保您已执行npm install mocha -g.然后只需在项目的根目录中运行mocha.

So if you haven't already, make sure you do npm install mocha -g. Then just run mocha in your project's root directory.
