[LRUG] Speeding up Cucumber

[Steve Tooke]

To echo what Murray said its most likely a slow boot time for your app.
Especially if it's been around a while and has a number of included gems.

There are a couple of things you can do to establish this.

First of all try a scenario that has a step that does nothing.

If this is taking a significant amount of time you can ease the startup
costs using spring or Zeus as suggested.

If this doesn't seem to be too bad, you could try targeting a static page
in your public directory. If this is significantly slower the issue is
probably something around the web driver you are using. (Make sure you are
setting this scenario up in the same way as your slow scenario, the same
tags etc).

If the static page isn't too bad, it's likely something around rendering
the actual page or setting up the context for the scenario that's slow.
