Question

How can I describe RSpec test to check if the array doesn’t include some value? Something like this:

tags.should include("one")
tags.should not include("two")

I can rewrite my condition:

tags.include?("two").should be_false

but I’m looking for more beautiful solution.

Answer 1

RSpec has should_not as well as should.

tags.should include("one")
tags.should_not include("two")

Here some more examples of the include matcher.
