Lazy evaluation matchers?

Ruby

Hi all,

Does anyone know what Lazy evaluation matchers are in Ruby Unit testing?
Are they a framework-specific thing like RSpec, or can they be achieved with test-unit and or minitest?

thanks

I don’t know what a “lazy evaluation matcher” is - do you have an example?

But minitest’s let is lazy: http://ruby-journal.com/minitest-let-is-lazy/
