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

$ rake test ran out of the rails 5.0 box.

Answer 2

Another way to do this using only Ruby's standard library is with Dir.glob. From within a ruby file, this would look like this:

require "minitest/autorun"

Dir.glob("**/*Test.rb") { |f| require_relative(f) }

Or from the commandline, you can use this command:

ruby -I . -e "require 'minitest/autorun'; Dir.glob('**/*Test.rb') { |f| require(f) }"

Dir.glob('**/*Test.rb') recursively searches the current directory for any file which matches *Test.rb, so we simply take all those files and require or require_relative them. From the commandline, require_relative fails, so we use require but first add the current directory to the $LOAD_PATH through -I .

Answer 3

This can also be done via a Makefile.

default:
  echo "Dir.glob('./test/*_test.rb').each { |file| require file}" | ruby

running make will run all your tests.
