Overview

Simple data structure for what a test method contains.

Too lazy to make a class for this when it’s really just a bag of data without any behavior.

Includes the name of this method, what line on the file it begins on, and where it ends.

def self.create suite_class, test_method
  # Hopefully it's been defined as an instance method, so we'll need to
  # look up the ruby Method instance for it
  method = suite_class.instance_method test_method

  # Ruby can find the starting line for us, so pull that out of the array
  start_line = method.source_location.last

  # Ruby can't find the end line however, and I'm too lazy to write
  # a parser. Instead, `method_source` adds `Method#source` so we can
  # deduce this ourselves.
  #
  # The end line should be the number of line breaks in the method source,
  # added to the starting line and subtracted by one.

  end_line = method.source.split("\n").size + start_line - 1

  # Shove the given attributes into a new databag
  new test_method, start_line, end_line
