# Ensures that requesting +path+ using +method+ routes to +options+.
|
|
#
|
|
# If you don't specify a controller, it will use the controller from the
|
|
# example group.
|
|
#
|
|
# +to_param+ is called on the +options+ given.
|
|
#
|
|
# Examples:
|
|
#
|
|
# it { should route(:get, "/posts").
|
|
# to(:controller => :posts, :action => :index) }
|
|
# it { should route(:get, "/posts/new").to(:action => :new) }
|
|
# it { should route(:post, "/posts").to(:action => :create) }
|
|
# it { should route(:get, "/posts/1").to(:action => :show, :id => 1) }
|
|
# it { should route(:get, "/posts/1/edit").to(:action => :edit, :id => 1) }
|
|
# it { should route(:put, "/posts/1").to(:action => :update, :id => 1) }
|
|
# it { should route(:delete, "/posts/1").
|
|
# to(:action => :destroy, :id => 1) }
|
|
# it { should route(:get, "/users/1/posts/1").
