Unit test expressJwt middleware with mocha js

Question

I am trying to figure out how to unit test the following route using Mocha.

router.delete('/auth/cut', expressJwt({ secret: global.secret }), function (req, res, next) {
    if (!req.user) {
        res.status(401).send().end();
    } else {
        fileProcessor.cut(req, res);
    }
});

I am using Middleware that validates JsonWebTokens and sets req.user. This is the test that i have

it('DELETE /auth/cut responds Success' , function (done) {
            request(sharedVars.server)
                .delete('/api/archive/auth/cut')
                .set('Authorization', 'Bearer tokenid')
                .set('filename', 'dictionary.zip')
                .end(function (err, result) {
                if (err) {
                    throw err;
                }
                expect(result.status).to.equal(200);
                done();
            });
        });

The following lines

.set('Authorization', 'Bearer tokenid')
.set('filename', 'dictionary.zip')

Are being passed via the Header

When i run the test i always get a 404 status, meaning the route is not found. What am i doing wrong? I think the problem is because of the Middleware inside the route.
