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?

etc…

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
Then I want to have

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.
