This allows test classes that are not subclasses of
ActiveSupport::TestCase (like those in rspec-rails) to interact with
with this variable without having to reference ActiveSupport::TestCase.
Assigning cookies for test cases should now use cookies[], e.g:
cookies[:email] = 'user@example.com'
get :index
assert_equal 'user@example.com', cookies[:email]
To clear the cookies, use clear, e.g:
cookies.clear
get :index
assert_nil cookies[:email]
We now no longer write out HTTP_COOKIE and the cookie jar is
persistent between requests so if you need to manipulate the environment
for your test you need to do it before the cookie jar is created.
- cookies can be set using string or symbol keys
- cookies are preserved across calls to get, post, etc.
- cookie names and values are escaped
- cookies can be cleared using @request.cookies.clear
