rspec users - Oct 2012 - change() vs change{}

Hi,

I am doing the rails tutorial and there is a line:

expect { click_button submit }.not_to change(User, :count)

When I looked up the rspec docs and book too, I found:

change {} documentation (using curly brackets).

Could someone tell me what the difference is, and if I use a block for
the above example, what would it look like?

I am very confused about why there are two versions and can''t seem to
get examples for the block {} version to see it''s proper usage.

Many thanks!

Kevin McCaughey

Not sure which docs you looked at, but both () and {} are supported,
as described in rspec''s rdoc:
http://rubydoc.info/gems/rspec-expectations/RSpec/Matchers#change-instance_method
