test.js

var Mocha = require('mocha'),
    fs = require('fs'),
    path = require('path');

// First, you need to instantiate a Mocha instance.
var mocha = new Mocha({
    timeout:50000,
    reporter: 'spec'
});

// Then, you need to use the method "addFile" on the mocha
// object for each file.

//// Here is an example:
//fs.readdirSync('./test').filter(function(file){
//    // Only keep the .js files
//    return file.substr(-3) === '.js';
//
//}).forEach(function(file){
//        // Use the method "addFile" to add the file to mocha
//        mocha.addFile(
//            path.join('./test', file)
//        );
//    });

mocha.addFile('./test/DeviceTest.js');

// Now, you can run the tests.
mocha.run(function(failures){
    process.on('exit', function () {
        process.exit(failures);
    });
});
