i've looked @ beforeeach functions cant seem make work

var chai = require('chai'); var chaihttp = require('chai-http'); var app = require('../app'); var should = chai.should(); var expect = chai.expect; chai.use(chaihttp);  var username = 't@t.com'; var password = 'test';  before(function() {  it('should login details login form / post', function(done) {     var request = chai.request(app);     request         .post('/session/new')         .field('email', username)         .field('password', password)         .end(function(err, res) {             res.should.have.status(200);             res.should.be.html;             done();         }); }); describe('vouchers', function() {     it('should list vouchers on / get', function(done) {         var request = chai.request(app);         request             .get('/vouchers')             .end(function(err, res) {                 res.should.have.status(200);                 res.text.should.match(/welcome voucher homepage/);                 res.should.be.html;                 done();             });     }); }); }); 

you cannot put it inside before hook. i've tried see happen , got various results. behavior doing undefined.

looking @ code, looks want code in first it initialize state , have stuff in describe run afterwards. so, unwrap code you've put in first it , make body of before hook. , since chai-http produces promises, should able return request produce. should work:

before(function() {     var request = chai.request(app);     return request         .post('/session/new')         .field('email', username)         .field('password', password)         .end(function(err, res) {             res.should.have.status(200);             res.should.be.html;         }); });
