--[[
	Functions should at least be tested against:
	- empty array
	- array with single item
	- array with multiple items
	- array
	- object
	- nil
	Testing methods naming convention:
	- Basic syntax for method name is: "Should[n't] <expectation> [after <action>] [when <condition>]" 
	- Shorthand negation is preferable (not "does not" but "doesn't")
	Common names are:
	- Should <expectation> when the array is empty
	- Should <expectation> when the array has only one element [and <condition>]
	- Should return a new array
	- Shouldn't modify itself
	- Should return correct result [when <condition>]
	- Should return an array equal to the original one when <condition>
