NodeJS and supertest : start tests with npm command

Question

I use supertest. I want to launch all tests in tests directory.
My /tests/tests.js file :

var request = require('supertest');
var app = require('express.io')();

//add good url with http:// and redirection 
request(app)
  .post('/add/')
  .expect(201)
  .send({url: 'http://www.google.fr'})
  .end(function(err, res){
      console.log(res.body.url);
    if (err) throw err;
    request(app)
        .get('/redirect/' + res.body.url.generatedid)
        .expect(302)
        .end(function(err, res){
            if (err) throw err;
         });
});

//add good url with www. and redirection  
request(app)
  .post('/add/')
  .expect(201)
  .send({url: 'www.google.com'})
  .end(function(err, res){
    if (err) throw err;
       request(app)
        .get('/redirect/' + res.body.url.generatedid)
        .expect(302)
        .end(function(err, res){
            if (err) throw err;
         });
    });

I want to launch with the npm command : npm run tests.
I changed my package.json file.

    {
  "name": "UrlShortener",
  "version": "0.0.1",
  "description": "Licence pro Web JS project",
  "main": "index.js",
  "scripts": {
    "start": "node index",
    "release" : "npm install",
    "tests" : "supertest tests/*.js",
    "dev" : "DEBUG=feedback supervisor index"
  },
  "dependencies": {
    "express.io": "^1.1.13",
    "mongoose": "^3.8.21",
    "nunjucks": "^1.1.0",
    "short-id": "0.1.0-1",
    "socket.io": "^1.2.1",
    "validator": "^3.27.0"
  },
  "devDependencies": {
   "supertest": "^0.15.0"
 },
  "engines": {
    "node": "0.10.x"
  }
}

npm run start works but when I try npm run tests I have :

> UrlShortener@0.0.1 tests c:\Users\Damien\Desktop\Nouveau dossier\urlshortener
> supertest tests/*.js

'supertest' n'est pas reconnu en tant que commande interne
ou externe, un programme exécutable ou un fichier de commandes.

How to launch my tests (supertest) with npm command ?

Answer 1

supertest package doesn't contain an executable script. Replace your scripts.tests in package.json to this:

"scripts": {
  "tests" : "node tests/tests.js"
}

You can specify which test files should be run in tests.js by requiring them.
