This is a stupid simple example of how easy it is to make a minitest plugin that does something useful. In this case it wraps assert so that failed assertions will drop into the ruby debugger.
Add this to the top of your test file or helper:
require 'minitest/debugger' if ENV['DEBUG']
Then run your tests as normal but define DEBUG=1:
% DEBUG=1 rake test
Debug.rb
Emacs support available.
Run options: --seed 27343
# Running tests:
.Assertion Failed. Dropping into debugger now:
./lib/minitest/debugger.rb:40:
(rdb:1) up 2
#3 example.rb:18:in `test_assert_failure'
(rdb:1) l
[13, 22] in example.rb
13 def wrong
14 24
15 end
16
17 def test_assert_failure
=> 18 assert_equal 42, wrong
19 end

21 def bad
22 raise "no"
