Testing Node with Superagent and Mocha

Question

when I run this code below, the user is logged in and the browser is redirected to a new route home. How do I structure the test below to validate that /home is being redirected to.

The application is working fine, I am just trying to get my test cases in order.

Thanks

   it('should login user',
    function(done) {
        request
        .post(url.parse('http://localhost:3000/login'))
        .send({
            userName: "[email protected]", password: "xyzpassword"
        })
        .end(function(res) {
            res.statusCode.should.equal(302);
            done();
        })
    });

additional information... the code works but is failing with the stackdump so I am unable to verify that the test is successful or not

From the superagent docs

Response header fields

The res.header contains an object of parsed header fields, lowercasing field names much like node does. For example res.header['content-length'].

So you can check along the lines of:

(/home$/).test res.header['location']

For your redirect test case.
