".WARNING: Tried to inspect exception outside of Pry::rescue{ }" when trying to use from non-rails minitest test

Hi,
I'm using minitest for doing web testing (for external sites) and want to use pry-rescue for this.

So far I'm running into problems:

# Running tests:

My setup is a very simple Rakefile:

require 'rubygems'
require 'bundler/setup'
require 'rake/testtask'

Rake::TestTask.new do |t|
  t.test_files = FileList['examples/**/*.rb']
end

The failing test would be:

require_relative 'test_helper'

class PryTest < PenTest::TestCase

  def setup
    Capybara.app_host = 'http://snikt.net'
  end

  def test_pry_interactive_debugger
    assert false
  end
end

with "test_helper.rb" being:

require 'minitest/autorun'
require 'pry-rescue/minitest'

require 'capybara'
require 'capybara/dsl'
require 'capybara/poltergeist'

require 'minitest/colorize'

# Capybara and poltergeist configuration
Capybara.default_driver = :poltergeist
Capybara.run_server = false

module PenTest
  class TestCase < MiniTest::Unit::TestCase
    include Capybara::DSL
  end
end

Could you help me? What am I doing wrong?

thanks in advance, Andreas
