ReferenceError: describe is not defined NodeJs

manpreet Best Answer 2 years ago

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);

and in func1.js:

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

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(); }); }); });

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

describe('Account', function() {
^

How can I fix the issue?

You can do like this:

  var mocha = require('mocha')
  var describe = mocha.describe
  var it = mocha.it
  var assert = require('chai').assert

  describe('#indexOf()', function() {
    it('should return -1 when not present', function() {
      assert.equal([1,2,3].indexOf(4), -1)
    })
  })
