Coach Guide

You heard about Rails Girls and want to be a coach? Here you’ll find all you need to know what coaching actually means.

What it takes to be a coach

First of all, Coaches are patient, tolerant and open people! This goes for everything, but also for technologies and solutions you might not chose for yourself. Whether or not you like RSpec or TestUnit, ERB or Haml, or whatever text editor you prefer does not matter to students at all. They are in a learning position and whatever gets them started, curious and eager to learn is a perfect tool – no matter your personal preferences. Keep in mind that your preferences – just like "common knowledge of the community" – is a result of a long, long learning process which you, and the community have gone through. Give your students the same chance to discover. Our goal is to get people started, learning and staying excited about coding!

# Provides an rspec version https://github.com/rails/rails/blob/master/activemodel/lib/active_model/lint.rb
# Approaches like https://gist.github.com/msgehard/910773 do not seem to work with
# current versions of minitest.
#
# Usage:
# 1. Put file in spec/support
# 2. Add it_behaves_like 'ActiveModel' in your spec file
