== DESCRIPTION:

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.

== FEATURES/PROBLEMS:

* Failed assertions drop into the debugger.
* Unhandled exceptions already drop into the debugger.

== SYNOPSIS:

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
       20  
       21    def bad
       22      raise "no"

== REQUIREMENTS:

* minitest... you probably already have it

== INSTALL:

* sudo gem install minitest-debugger
