title: puts and binding.pry output is not visible in test environment
body: <p>I use minitest and rake task to run tests. I use standard reporter (this is from test helper):</p>
  
  <pre><code>Minitest::Reporters.use!(
    Minitest::Reporters::DefaultReporter.new(fast_fail: true, slow_count: 3),
    # show single tests with the spec reporter
    # MiniTest::Reporters::SpecReporter.new,
    ENV, Minitest.backtrace_filter
  )
  </code></pre>
  
  <p>This is my test.rake:</p>
  
  <pre><code>require 'rake/testtask'
  
  Rake::Task['test:run'].clear
  Rake::Task['test:decorators'].clear
  
  namespace :test do
    task run: ['test:decorators', 'test:models', 'test:controllers', 'test:mailers', 'test:integration']
  
    Rake::TestTask.new(decorators: 'test:prepare') do |t|
      t.pattern = 'test/decorators/**/*_test.rb'
    end
  end
  </code></pre>
  
  <p>I also have pry installed in Gemfile:</p>
  
  <pre><code>group :pry, :test do
    gem 'pry-rails'
    gem 'pry-byebug'
  end
  </code></pre>
  
  <p>The problem I can't use it in tests. I can add a breakpoint with <code>binding_pry</code>, but I don't see the output from invoked functions. I can't also log anything using <code>puts</code> (from both pry and directly from tests). I don't see this output nor in terminal nor in log files. The only thing I can use at the moment is a Rails logger. But it's not satysfying. How can I display output from pry and puts in terminal?</p>
