Question

It’s a simple question. I have Cucumber steps, for example:

Given /We have the test environment/ do
  @user = # Create User model instance
  @post = # Create Post model instance
  # etc...
end

In the Then step I’m using my own classes, they simplify the process of testing:

Then /all should be fine/ do
  # MyValidatorClass has been defined somwhere in features/support dir
  validator = MyValidatorClass.new
  validator.valid?.should be_true
end

Inside the MyValidatorClass instance, I deal with the above instance variables @user, @post, etc.

What is the best and simpliest way to access Cucumber variables from MyValidatorClass class instance?

class MyValidatorClass
  def valid?
    @post
    @user
  end
end

Now I have manually passed all arguments to MyValidatorClass instance:

validator = MyValidatorClass.new @user, @post

But I think this purpose is bad. I need something more transparent, because we are using Ruby, that why!

What is the best way to do this?

Answer 1

I have found the posible soultion. You just should migrate from instance variables to class variables:

Given /We have the test environment/ do
  @@user = # Create User model instance
  @@post = # Create Post model instance
  # etc...
end

Then /all should be fine/ do
  # MyValidatorClass has been defined somwhere in features/support dir
  validator = MyValidatorClass.new
  validator.valid?.should be_true
end

...    

class MyValidatorClass
  def valid?
    @@post
    @@user
  end
end
