[c++][cucumber-cpp] Calling Steps from Step Definitions

[Victor Emilio Armengol Fernandez]

Hi guys, In the ruby documentation you can call a step from a step definition with this:

Given /^(.*) is logged in$/ do |name|
  step "the user #{name} exists"
  step "I log in as #{name}"
end

What is the equivalent "step" function in cucumber-cpp ?

Thanks in advance.

Though you can do this, I'd advise strongly against it. Instead call helper methods instead. So with your example

module UserStepHelper

  def create_user(name:)

     ...

   end

   

   def log_in(user:

      ...

    end

end

World UserStepHelper

Given 'the user #{name} exists' do |name|

   @user = create_user

Given /^(.*) is logged in$/ do |name|

  login_user(create_user(name: name)

end




Treat each step definition as a call to a helper method. (solving simply problem of matching scenario statements to step definitions). Then solve the problem of having  a single method call do alot of stuff in your programming language (programming languages are designed for this task)

And now your question becomes how do I create helper methods in Cucumber CPP. A question I hope someone else can answer (I don't use CPP)

All best




Andrew

Thanks, this looks a good solution to reuse some code, and seems the only one, I was looking for a way to have a try-catch step that could handle any other step, i.e.

GIVEN("^try (.*)$"){

    REGEX_PARAM(string, otherStep);

    try{
        UNKNOWN_CODE_TO_CALL_OTHER_STEP(otherstep);
    }catch(Exception e){ ... }

} 

but it seems the only way should be to have to versions of each step, one with try and the other whitout it, and call the helper methods from each one.
