How to test Connect / Express middleware?
express, node.js, unit-testing
Solution
supertest does the job, as pointed out by SLaks in the comments.
Problem
Supposed I have a middleware for Connect and / or Express. What's the best way to unit test this middleware? Of course, I can set up an http server in the unit tests, and load the middleware into this. But supposed that I want to test startup behavior, I need several http servers, which soon gets complicated and unclear (think of using a new port in each single test). Is there a better way, or is testing it inside a real server the best one can come up with?
