Can't access Sails.js app instance in integration tests - testing

Question

I'm trying to write some integration tests in sailsjs. I have a bootstrap.test.js file that lifts my server in a global before as the docs suggest.
In my integration test when I try to pass my sails app to supertest I get an error:
app is not defined
agent = request.agent(app.hooks.http.app);
^
bootstrap.test.js
var Sails = require('sails'),
Barrels = require('barrels'),
app;
before(function(done) {
console.log('Global before hook'); // Never called?
this.timeout(5000);
Sails.lift({
log: {
level: 'error'
},
models: {
connection: 'test',
migrate: 'drop'
}
}, function(err, sails) {
app = sails;
if (err) return done(err);
var barrels = new Barrels();
fixtures = barrels.data;
barrels.populate(function(err) {
done(err, sails);
});
});
});
// Global after hook
after(function (done) {
console.log(); // Skip a line before displaying Sails lowering logs
Sails.lower(done);
});
integration test
var chai = require('chai'),
expect = chai.expect,
request = require('supertest'),
agent = request.agent(app.hooks.http.app);
describe('Species CRUD test', function() {
it('should not allow an unauthenticated user create a species', function(done){
var species = {
scientificName: 'Latin name',
commonName: 'Common name',
taxon: 'Amphibian',
leadOffice: 'Vero Beach',
range: ['Florida', 'Georgia']
};
agent.post('species')
.send(species)
.end(function(err, species) {
expect(err).to.exist;
expect(species).to.not.exist;
done();
});
});
});

I have been trying to make the integration test work for a few days now. This seems to be working fine in my environment. Maybe you can give it a try.
bootstrap.test.js
var Sails = require('sails');
var sails;
before(function(done)
{
Sails.lift({
log: {
level: 'error'
},
connections: {
testDB: {
adapter: 'sails-memory'
}
},
connection: 'testDB',
}, function(err, server)
{
sails = server;
if (err) return done(err);
done(err, sails);
});
});
after(function(done)
{
Sails.lower(done);
});
Test
var request = require('supertest');
it('should return all users', function(done){
request(sails.hooks.http.app)
.get('/user)
.expect(200)
.expect('Content-Type', /json/)
.end(function(err, res){
// check the response
done();
);
}
I place bootstrap.test.js on the root of my test folder and then use mocha to run the test.
mocha test/bootstrap.test.js test/**/*.test.js
Hope this help.

it seems that since version 3.x of mocha, nodejs global variables capabilities was removed. so if you need it, you should specifically pass it to your environment like that:
mocha --globals global test/bootstrap.test.js test/**/*.test.js
or
in your mocha.opts file :
#test/mocha.opts
--globals global
