Please always include the versions of Rails and RSpec that you are using when
asking for help. Things are different in different versions. I'm going to
assume you're using rails-3 and rspec-rails-2.
The name of the example begins with "should re-direct ...". The rails testing
framework lets you assert that a specific template is rendered or that there is
a redirect, but not both in the same action.
You also have to invoke an action on the controller in each example for
anything to happen. e.g.
describe "POST create" do
describe "with valid params" do
it "redirects to the created channel" do
post :create, :channel => valid_attributes
response.should redirect_to(Channel.last)
end
end
describe "with invalid params" do
it "re-renders the 'new' template" do
Channel.any_instance.stub(:save).and_return(false)
post :create, :channel => {}
response.should render_template("new")
end
end
end
Take a look at the generated controller spec when you run 'rails generate
scaffold ...': https://gist.github.com/942203. If that doesn't make sense, feel
free to ask questions.
HTH,
