Overview

I provide a way of passing state around between tests that isn’t instance variables.

This is handy even in plain old Cucumber-land (where if you typo an instance variable, you just get nil), and essential in a set of mostly-independent step adapter objects, each with their own private state.

Instance Method Summary

• #fetch_or_default(key, &block) ⇒ Object

  • And a variant of fetch that, if the key is not found, sets it for the next caller.

• #initialize ⇒ Context constructor

  A new instance of Context.

Constructor Details

#initialize ⇒ Context

Returns a new instance of Context.

# File 'lib/hypercuke/context.rb', line 12

def initialize
  @hash = {}
end

Instance Method Details

#fetch_or_default(key, &block) ⇒ Object

• And a variant of fetch that, if the key is not found, sets it for the next caller.

This behavior is in the spirit of the ||= operator, except that it won’t short-circuit and call the default value if the key is present, but set to nil or false.

# File 'lib/hypercuke/context.rb', line 32

def fetch_or_default(key, &block)
  @hash[key] = @hash.fetch(key, &block)
end
