rspec users - Oct 2009 - Running a specific row in cucumber example table

I want to be able to execute only 1 row in an Scenario/Outline Example
table. Is there a method already created for me to access. I have
certain validation rules for only running 1 row of data coming from an
external request to execute cuke.

So having something in a step_definition file like:

test.rb

If $something
   table.row.skip
end

Before do
  pending
end

etc...

I have no idea if this will work, but you could try to sense for the  
table row you want to skip in a Before block, then call skip_invoke!  
on it:

Before(scenario_or_example_row) do
   if the_one_to_skip?(scenario_or_example_row)
     scenario_or_example_row.skip_invoke!
   end
end

That might work for you, but you should be aware that #skip_invoke! is  
not part of the public API right now and might be changed without  
warning.

Obviously you''ll have to write #the_one_to_skip? method yourself...

It would probably be better to be able to tag the example table row,  
and just filter it out before the feature run. We can''t do that right  
now can we?

Well, this isn''t really working (or I might forgot something to define,
but from http://wiki.github.com/aslakhellesoy/cucumber/hooks  - it seems 
that ''Before'' is operating with tags (and hooks) - see

This is in fact be useful, because we are able execute code before each 
line of the properly tagged Scenario Outline... but... I still don''t 
know the method/variable to access the _current line_ of the example 
table.

So translated into the code, an example:

x.feature:
...
@tagged
Scenario Outline: file reader
Given I read <file>
Then I want to have <content>

Examples:
| file | content |
| x.txt | Text |
| y.txt | Other text |

***************************
step_definitions/x.rb

Before(''@tagged'') do
   # how to access current row???
   if row[0] == $external_filename
     # how to properly skip current line???
     row.skip_invoke!
   end
end

Given /I read (.+)/ do |fileName|
   #open and read fileName
   #fill @file_content
end

Then /I want to have (.+)/ do |content|
   #assert ''content'' against @file_content
end

**********************************

So we need something for ''row[0]'' and a proper way to skip the
current
line...

I now that this example is not a good real life situation (it would be 
easier to use multiline step arguments), but we would like to use 
Cucumber driven by an external source (executing only one line from each 
example table) AND maintaining the ability to run it independently (all 
lines)

I hope this cleared up the things a bit more...

Thanks for your ideas!

Sorry, my example is bollocks. Try this instead:

Before do |scenario_or_example_row|
   if the_one_to_skip?(scenario_or_example_row)
     scenario_or_example_row.skip_invoke!
   end
end

So the thing yielded to the Before block is the Scenario object if  
you''re in a Scenario, or the OutlineTable::ExampleRow if
you''re in an
outline table. You can call skip_invoke! on either of those objects to  
tell them not to invoke their step definition.
