Cucumber table persistance

cucumber_table_persistence.feature

Feature: Table persistence

Scenario: We try to modify a table and it keeps its changes when we pass it to another step
  When we have the following table and then set an arbitrary value inside the step definition
   | one | 1 |
   | fizz | buzz |
  Then the table should retain this modification when passed to another step

cucumber_table_persistence_steps.rb

When /^we have the following table and then set an arbitrary value inside the step definition$/ do |table|
  table.hashes.first[:foo].should == nil
  table.hashes.first.update(:foo => :bar)
  table.hashes.first[:foo].should == :bar

  step "the table won't retain this modification when passed to another step", table
end

When /^the table should retain this modification when passed to another step$/ do |table|
  table.hashes.first[:foo].should == :bar
end
