# 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').to('posts#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').to('posts#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').
