Node.js Question

NodeJS and supertest : start tests with npm command

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

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.
