A Ruby Step Definition holds a Regexp and a Proc, and is created by calling Given, When or Then in the step_definitions ruby files. See also RbDsl.
Example:
Given /I have (\d+) cucumbers in my belly/ do # some code here end
# File lib/cucumber/rb_support/rb_step_definition.rb, line 26 def initialize(rb_language, regexp, proc) raise MissingProc if proc.nil? if String === regexp p = Regexp.escape(regexp) p = p.gsub(/\\\$\w+/, '(.*)') # Replace $var with (.*) regexp = Regexp.new("^#{p}$") end @rb_language, @regexp, @proc = rb_language, regexp, proc @rb_language.available_step_definition(regexp_source, file_colon_line) end
# File lib/cucumber/rb_support/rb_step_definition.rb, line 49 def ==(step_definition) regexp_source == step_definition.regexp_source end
# File lib/cucumber/rb_support/rb_step_definition.rb, line 53 def arguments_from(step_name) args = RegexpArgumentMatcher.arguments_from(@regexp, step_name) @rb_language.invoked_step_definition(regexp_source, file_colon_line) if args args end
