Debug techniques

Chris and I (Andrew Black) were discussing how to get a cucumber test to stop and get into debug (or irb). I have come up with two different ways by googling. It would be nice to choose the better one (or combine them) and get this into the app.

How to call

• Place a step called cucumber
• Add a tag @stop to the step you want to debug
• Add a call to debugger in the ruby code you want to

What to do when you stop

• call rdb (ruby debugger)
• call irb (interactive ruby)
• call pry ( suggestion by Chris Adams - not tried yet)

How implemented

Detailed code

step_definitions/debug_steps.rb

     When "debugger" do
        debugger
     end

support/stop.rb

         # Usage:
         #  @wip @stop
         #  Scenario: change password
         #    ........................
         # $ cucumber -p wip
     # Comes from :

     # 
     # orinal jhad 
     #  ... scenario.failed? && scenario.source_tag_names.include?("@wip") &&
         After do |scenario|
           if  scenario.source_tag_names.include?("@stop")
             puts "Scenario failed. You are in rails console becuase of @stop. Type exit when you are done"
             require 'irb'
             require 'irb/completion'
             ARGV.clear
             IRB.start
           end
         end
