Defined in:
lib/cucumber/ast/py_string.rb

Overview

Represents an inline argument in a step. Example:

Given the message
  """
  I like
  Cucumber sandwich
  """

The text between the pair of """ is stored inside a PyString, which is yielded to the StepDefinition block as the last argument.

The StepDefinition can then access the String via the #to_s method. In the example above, that would return: "I like\nCucumber sandwich"

Note how the indentation from the source is stripped away.
