To install ruby-debug gems, please visit this page
I created a simple steps definitions to invoke ruby-debug:
When /^I go into debug mode$/ do
Then, I can simply use the steps definition in any cucumber scenario.
Scenario: A simple google search scenario
Given I am on the main google search
And I search for "site:qastuffs.blogspot.com"
And I click on the search button
And I go into debug mode
And I click on the first result
Then I should land on the qastuffs blog
The above cucumber scenario will run the browser to google.com to do a search on site:qastuffs.blogspot.com. Then it will hit the debug mode and it will pause. You will see the following text "(rdb:1) on your console where you can print your test variables.
To see all of commands that you can run in ruby-debug, simply type in "h" and press enter
ruby-debug help v0.10.3
' for help on a specific command
backtrace delete enable help next quit show up
break disable eval info p reload step var
catch display exit irb pp restart thread where
condition down finish list ps save trace
continue edit frame method putl set undisplay
