Write simple rspec tests on one line for fun and profit

If you have a test set up that performs one assertion then you can condense your test into one line, this makes things way more readable and shortens your tests.

For example:

it "should return a response header with JSON in it" do
  response.header['Content-Type'].should include 'json'
end 

Can become:

it { response.header['Content-Type'].should include 'json' }

When you have lots of small tests like this it really helps to make your tests easier to read, which will in turn help you in keeping them up to date and sharing them with other people.
