'require'ing files from other directories

I’m going through The RSpec Book and am currently working with the
Mastermind game example.

But that’s besides the point.

The way my directories are setup is like so:

/mastermind/features/step_definitions…
/mastermind/lib/codebreaker/…

I have a file in step_definitions that’s giving me an error for an
uninitialized constant. My guess is I need to ‘require’ the file where
that class is defined. Said files is located in /lib/codebreaker.

I am very new to Ruby so this is probably a really simple question but
how do I ‘require’ a file in codebreaker from a file inside
step_definitions?

Usually you can do some relative path requires, you can do it on your
spec/spec_helper.rb

require File.expand_path("…/…/lib/codebreaker", FILE)

or, another common setup is to add the “lib” into require path list, and
them just require the file:

$: << File.expand_path("…/…/lib", FILE)

require “codebreaker”

another hint: you should require only main file of lib (codebreaker),
and
this file in lib should require the others (also, if you have some time,
research about autoload, will be useful too ;))

You could try asking on the RSpec Book’s own forum:

This question is really more Cucumber related so you could also ask on
the cukes google group.

Your guess is right. The best place to put your require statement is in
features/support/env.rb

I’m surprised that the book doesn’t tell you to do that - did you maybe
miss a step?

require ‘codebreaker’

I ended up getting it to work after a co-worker pointed out that I need
to add “./lib” to some thing in ruby’s list of directories to look in. I
don’t remember what terminology he used but he did it through the
terminal.

He probably called it the ‘load path’. That’s what the $: means in that
snippet - it’s an Array of paths where Ruby will search for files when
you call require. In the code above, you’re pushing the lib directory
onto the load path.

The require statement I ended up using is

require ‘codebreaker/game’

Maybe the lib/codebreaker file was supposed to do that?

It should, mine currently has

require ‘codebreaker/game’
require ‘codebreaker/marker’

All best
