How to run all tests with minitest?

Question

I downloaded source code for a project, found a bug, and fixed it.

Now I want to run tests to find out if I have broken anything.

The Tests are in minitest D

Answer 1

Here is my entire rakefile, which I put in my top directory:

task :default => :test
task :test do
  Dir.glob('./test/*_test.rb').each { |file| require file}
end

To run all my test files at once, I just type rake. That's it!

Make sure to have require 'minitest/autorun' at the top of each of your Minitest files. Dir.glob definitely DOES work with Minitest.

To get pretty, colored Minitest output, with names of all my test methods, I have the file minitest_helper.rb in my /test directory. (Had to install the gem minitest-reporters):

require 'minitest/reporters'
Minitest::Reporters.use!(Minitest::Reporters::SpecReporter.new)
require 'minitest/autorun'

I just had to require_relative './minitest_helper' at the top of each of my test files.
