Match render :nothing

Testing RSpec

Hello guys,

Is there any way to match a render :nothing?

I coudn’t find any way to do this so i’ve just changed my controllers
to do a “head :ok”, but it would be nice to know if there is any other
way :slight_smile:

I’m pretty sure you can do
response.body.should be_blank # or == “”

If you don’t like how it reads, you could create a custom
render_nothing matcher.

Hi Pat,

'response.body.should be_empty" does not work :frowning:

The string on the response after a “render :nothing” is " " (one space
character), so i had to do a strip to make it work. I guess i’ll write
my own render_nothing matcher anyway. Here’s how it is now:

  @assignments.should_receive( :find ).and_return( [ @assignment ] )
  @assignments.should_not_receive( :create )
  do_xhr
  response.should be_success
  response.body.strip.should be_empty

Oi Maurício,

I would put should_not_receive(:create) in a separate example as it’s
a different concept from rendering nothing.

 do_xhr
 response.should be_success
 response.body.strip.should be_empty

You can use the simple_matcher method for this quite … simply:

 def render_nothing
   simple_matcher(:nothing) do |response|
     response.body.strip == ''
   end
 end

The failure message on this is quite verbose, and I have an idea about
a solution for that, but it’ll work :slight_smile:

Tchau,
David
