Minitag

A simple gem that allow developers using minitest to specify tags for their classes and tests, and run their test suite based on these tags.

This gem should be framework agnostic, let me know if you encounter any problems running this within the framework of your choice.

Installation

Add this line to your application's Gemfile:

gem 'minitag'

Or install it yourself as:

$ gem install minitag

Usage

Adding tags

We can tag specific classes or tests with one or more tags.

It is important to point out that tags associated with a class or test have no concept of being inclusive or exclusive. This distinction is only valid for tag filters.

class MyTest < Minitest::Test
  # Every test within this class will inherit this tag
  tag_namespace 'my_namespace_tag'

  # Only the test below will have this tag
  tag 'my_tag', 'another_tag'
  def test_hello_minitest
    # ...
  end
end

Running tests with tag filters

We can now run our test suite with specific tags:

$ bundle exec rake test --tag 'unit'

or even multiple tags:

$ bundle exec rake test --tag 'unit' --tag 'services' --tag '~model'

Examples

# Only run tests that are tagged with 'unit'
$ bundle exec rake test --tag 'unit'

# Only run tests that are NOT tagged with 'unit'
$ bundle exec rake test --tag '~unit'

# Only run tests that are tagged with 'unit' and are NOT 'parallel'
$ bundle exec rake test --tag 'unit' --tag '~parallel'
