m stands 🤘 (metal), which is a better test/unit test runner. @sferik took t so this was the next best option.
Basically, I was sick of using the -n flag to grab one test to run, like RSpec's test runner works.
Given this file:
$ cat -n test/example_test.rb
1 require 'test/unit'
2
3 class ExampleTest < Test::Unit::TestCase
4 def test_apple
5 assert_equal 1, 1
6 end
7
8 def test_banana
9 assert_equal 1, 1
10 end
11 end
You can run a test by line number, using format m TEST_FILE:LINE_NUMBER_OF_TEST:
$ m test/example_test.rb:4
Run options: -n /test_apple/
# Running tests:
