This is a project that illustrates learning a programming language by writing unit tests.
The Idea is to create a file for each concept, e.g.
classes.rb
method_definitions.rb
control_structures.rb
loops.rb
strings.rb
arrays.rb
hashes.rb
symbols.rb
iteration_idioms.rb # each, to
enumerator.rb # esp. map & inject in http://ruby-doc.org/core-2.0.0/Enumerable.html
regular_expressions.rb
reading_and_writing_files.rb
blocks_and_yield.rb # maybe just adapt https://github.com/neo/ruby_koans/blob/master/src/about_blocks.rb
reflection.rb # get method names, find out if an object responds to a method, send a message to an object where you have the method name in a string
First, you need to install rspec. You can either install it directly with
gem install rspec
Or use bundler to install it (which you will need for rails anyway)
gem install bundler
bundle
The latter installs all gems listed in Gemfile and creates Gemfile.lock stating the actual versions of the installed gems.
You can either run all tests with
rspec about/*.rb
or individual files with
rspec <filename>
