[rspec-users] [cucumber] how to debug cucumber with netbeans?
3 months ago, I submitted a patch to cucumber so I could run cucumber from a
ruby script and use the debugger in netbeans
(https://rspec.lighthouseapp.com/projects/16211/tickets/128-running-feature-from-ruby-script)
It worked well at the time but I can''t make it work with cucumber
0.3.2.
Here is the stacktrace:
ruby script/cucumber_netbeans_runner.rb
cucumber features/_admin/projects.feature --profile default
/Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in
`gem_original_require'': no such file to load -- lib/active_merchant

from script/cucumber_netbeans_runner.rb:29:in `run''
from script/cucumber_netbeans_runner.rb:21:in `run_feature''
from script/cucumber_netbeans_runner.rb:37
And the script:
require ''rubygems''
require ''cucumber/cli/main''
module Cucumber
module Netbeans
class Runner
def initialize(cucumber_opts=nil)
@argv = []
@cucumber_opts = cucumber_opts || " --profile default"
end
def run_scenario(line_number)
@cucumber_opts << " --line #{line_number}"
run
end
def run_feature(feature)
@argv << "#{feature}"
run
end
protected
def run
@argv << @cucumber_opts
puts %Q{cucumber #{@argv.join('' '')} \n}
Cucumber::Cli::Main.execute(@argv)
end
end
end
end
Cucumber::Netbeans::Runner.new().run_feature
"features/_admin/projects.feature"
I wonder if fellow netbeans on cucumber users will have an idea ...
Ironically, debugging that script with netbeans crashes the debugger at
Library/Ruby/Gems/1.8/gems/polyglot-0.2.5/lib/polyglot.rb:54
For the time being, I am using the "old school" ruby-debug which works
pretty well ...

What is confusing is that "lib/active_merchant" is showing up in the backtrace saying it can''t be found... What if you try to run the feature with the debugger from outside of Netbeans? Just trying to get an idea of who the culprit really is here. -Ben

I had never used it before as I come from a java + Eclispe background and always used an IDE to debug. I must admit that ruby-debug is very easy to use and it did well to find the cause of my problem: cucumber calling webrat visit with "eval". There was a bug in a before_filter of a controller which was doing an infinite loop. Apparently, the mac ruby interpreter did not like it and crashed with "segmentation fault". Running Rails in "development" mode was working fine and showing an exception stacktrace... This is the kind of situtation where TDD is actually slower than "prehistoric development with no tests". I spent 3 hours looking for the source of the problems and it took me 15 minutes running Rails in developement mode. In order to improve webrat, I''ll spend 1 hour this morning o try to write a spec to reproduce the bug. -- View this message in context: http://www.nabble.com/-cucumber--how-to-debug-cucumber-with-netbeans--tp23446299p23458483.html Sent from the rspec-users mailing list archive at Nabble.com.

Yeah, TDD/BDD certainly can slow you down at times especially on initial investments like this. It just comes down to if it is worth it for you and this project or if you would be fine with some technical debt. :) -Ben

However, I was successfull with ruby-debug, see http://www.sitepoint.com/article/debug-rails-app-ruby-debug/2/ In the meanwhile, I was successful reproducing the bug with a test in webrat : https://webrat.lighthouseapp.com/projects/10503/tickets/243-segmentation-fault-when-visiting-rails-action-with-infinite-loop A simple fix would be to replace the code generation created with "eval". I believe it might speed up also cucumber as eval is slower than normal ruby code ... -- View this message in context: http://www.nabble.com/-cucumber--how-to-debug-cucumber-with-netbeans--tp23446299p23497830.html Sent from the rspec-users mailing list archive at Nabble.com.
