Using PUT method on Supertest

Question

How do I use a PUT method with SuperTest? All I get is "404 Not found" as response.

The request handler:

router.put('/', function (req, res) {
    res.type('json');

    FooResource(req.body, function () {
        res.send("{}");
    });
});

The test suite:

describe("PUT /foo/fii", function () {

    it("Respond with 200", function (done) {

        request(app)
            .put('/')
            .set('Accept', 'application/json')
            .expect(200, done);

    });
});

Added:

    it("Respond with 200", function (done) {

        request(app)
            .put('/')
            .send("{}")
            .expect(200)
            .end(function(err, res) {
                done();
            })

    });

And now it works(?)
