Test-Driven Development

• Write test first.
• Correct the test so it passes. (Going Green)
• Refactor.

Differences Between "Let" and "Each" Matchers:

• Each creates a unique instance variable for each "it" unit test. Proper syntax is:

		before :each do
			@variable_name = ClassName.new
		end

• Let passes the same instance variable to all "it" unit tests. Proper syntax is:

		before :variable_name do
			ClassName.new
		end
