More loosely typed expression

Oliver Saunders

I'm just trying out RSpec with some really simple code. I have this
line:

@subject.num(0).fizz?.should == false

And I want it to pass if it's false OR nil. I tried using =~ but it made
no difference. Is there no way to do this in Ruby?

This doesn't exactly answer your question, but isn't it unusual to
have a method suffixed with a ? that doesn't return a boolean value?
Anyway, here's a solution:

@subject.num(0).fizz?.should_not be

Oh yeah, the reason I ask is because, if fizz? acted like other ?
methods, you could do

@subject.num(0).should_not be_fizz

Time for me to get new reading glasses, I got the sense of the test reversed.
