page 269, running rspec
These tests pass (after you update the .gemspec file):
$ rspec spec/aaagmnr/options_spec.rb
It would be worth to explicitly mention to cd to code/gems/aaagmnr before running the test. As I work in code, I had an error :
% rspec -fd gems/aaagmnr/spec/aaagmnr/options_spec.rb
An error occurred while loading ./gems/aaagmnr/spec/aaagmnr/options_spec.rb.
Failure/Error:
RSpec.describe Options do
...
NameError:
uninitialized constant Aaagmnr::Options
...
0 examples, 0 failures, 1 error occurred outside of examples
I was able to solve it by adding
require_relative '../../lib/aaagmnr'
in options_spec.rb, but it’s not what you have planned.
The trick is that if we are in code/gems/aaagmnr, RSpec can silently load .rspec
--format documentation
--color
--require spec_helper
which requires spec/spec_helper.rb. Thanks to require "aaagmnr" in spec_helper, all the required files are loaded.
Without this infrastructure in code/gems/aaagmnr, for example if I delete .rspec or spec_helper.rb, nothing works :
% rspec spec/aaagmnr/options_spec.rb
Resolving dependencies...
An error occurred while loading spec_helper.
Failure/Error: __send__(method, file)
LoadError:
