Creating a test rake task with Minitest
A simple way to create a rake task to run with Minitest
First, in your Rakefile (or lib/tasks/test.task or yet tasks/test.task) we need to require the rake/testtask :
require "bundler/gem_tasks"
require "rake/testtask"Now we can instantiate a new TestTask object, wich receives a block where we can configure the task.
Rake::TestTask.new do |t|
endIn the configuration block, we set the test files that will run in the test task (everything inside tests directory.
Rake::TestTask.new do |t|
t.test_files = FileList['tests/**/*_test.rb'] #my directory to tests is 'tests' you can change at you will
end
desc "Run tests"A good practice is to set the test task as default, we can do this adding this line in after creating the TestTask object.
ruby
task default: :test
Don't forget to require minitest/autorun to your test files.
The final file looks like this:
require "bundler/gem_tasks"
require "rake/testtask"
Rake::TestTask.new do |t|
t.test_files = FileList['tests/**/*_test.rb']
end
desc "Run tests"
task default: :testCheck other configuration options in the Rake::TestTask documentation.
Hope this helps! ;)

Thanks for this, I did want to note that typically the folder for tests is simply test without the s. Also from minitest's readme, they prefix files with test_ instead of postfixing them. So if you're following all conventions it ends up being
require "rake/testtask"
Rake::TestTask.new do |t|
t.test_files = FileList['test/**/test_*.rb']
end
desc "Run tests"
task default: :testThanks for the write up, just wanted to save someone else a bit of time.
