Because tests are code. Especially in Minitest, where each test file is a subclass
Add this line to your application's Gemfile:
And then execute:
Or install it yourself as:
$ gem install minitest-metz
There two ways that you can use this plugin:
You can apply the
--metz flag when you are running your tests. If present, the
plugin will run the
sandi_meter for the test that ran.
If you are willing of writing tests around the four rules, you can assert on them. The assertions works on basically any type of class, whether it is a test class or a production class. If you want to test the test class for the four rules:
class PersonTest < ::Test def test_sandi_four_rules assert_obey_metz(self.class) # Or.. assert_obey_metz(PersonTest) end end
If you want to test another class:
class PersonTest < ::Test def test_sandi_four_rules assert_obey_metz(Person) end end
Also, there's the option on asserting on a file path:
class PersonTest < ::Test def test_sandi_four_rules assert_obey_metz("lib/person/person.rb") end end
And, of course, you can use
refute_obey_metz, although I have no idea why
would you. But anyway, it's available for use. Have fun.
After checking out the repo, run
bin/setup to install dependencies. Then, run
rake test to run the tests. You can also run
bin/console for an interactive prompt that will allow you to experiment.
To install this gem onto your local machine, run
bundle exec rake install. To release a new version, update the version number in
version.rb, and then run
bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the
.gem file to rubygems.org.
