Express doesn't even have controllers though -- just a routing mechanism. If you set up your controllers so that they are independent from the routes, then they are just as easy to test. It could be as simple as: app.get('/users/:id', userController.userPage). You can then test userController.userPage(req, res, next) instead of the route.
