Diary of the development of a new feature using TDD

tdd_diary.rb

# Day 1, 12:00pm
# In facility_xml_generator_spec.rb, which tests the entry point for the feature I'm adding,
# I wrote a Given-When-Expect structured natural language description of my understanding of what it means for the feature to be there. 
# The only piece of code so far is the construction of the SUT and a tentative name for the method that provides the
# functionality without any params. 
describe 'Coded Types generation' do
  it '' do
			# Given that CSD codedType semantics are added to an RM's single option field by adding the metadata below to it:
			# CSDType => 'codedType', codingSchema => 'foo'

			# Given a collection C with three single option fields F, G, H
			
			# F doesn't have CSD coded type semantics

			# G is a list of fruits with coded type semantics
			# Values in G are: "A => Apple", "B => Banana", "P => Peach"
			# Metadata in G is: "CSDType => codedType", "codingSchema => fruits"

			# H is a list of supermarkets with coded type semantics
			# Values in H are: "C => Carrefour", "J => Jumbo"
			# Metadata in H is: "CSDType => codedType", "codingSchema => supermarkets"

			# X is a facility in collection C
			# X.G == 'Banana'
			# X.H == 'Jumbo'

			# When I generate XML for the coded types of X
			g = FacilityXmlGenerator.new collection
			coded_types = g.generate_coded_types

			# I expect:

			# Exactly two codedType elements CT1 and CT2 (order doesn't matter)

			# CT1 has the following features:
			# Attributes => code = 'B', codingSchema = 'fruits'
			# Text => "Banana"

			# CT2 has the following features:
			# Attributes => code = 'J', codingSchema = 'supermarkets'
			# Text => "Jumbo"
