How to test endpoints protected by csrf in node.js/express

How to test endpoints protected by csrf in node.js/express

I have implemented csrf (cross-site request forgery) protection in an
express like so:
...
app.use(express.csrf());
app.use(function (req, res, next) {
res.cookie('XSRF-TOKEN', req.csrfToken());
next();
});
...
This works great. Angularjs utilized the csrf token in all requests made
through the $http service. The requests that I make through my angular app
work great.
My problem is testing these api endpoints. I'm using mocha to run my
automated tests and the request module to test my api endpoints. When I
make a request to an endpoint that utilizes csrf (POST, PUT, DELETE, etc.)
using the request module, it fails, even though it correctly utilizes
cookies and such.
Has anybody else come up with a solution to this? Does anyone need more
information?
Example of test:
function testLogin(done) {
request({
method: 'POST',
url: baseUrl + '/api/login',
json: {
email: 'myemail@email.com',
password: 'mypassword'
}
}, function (err, res, body) {
// do stuff to validate returned data
// the server spits back a 'FORBIDDEN' string,
// which obviously will not pass my validation
// criteria
done();
});
}
