should_assign_to raises ScriptError "No action was performed or declared."

[Wayne Conrad]

Hello. Remarkable newbie, writing tests for some very old, very
crusty rails code. I'm stumped by a strange exception, "No action was
performed or declared," when using the should_assign_to matcher.

(Part of) the controller:

class IndexController < ApplicationController

def initialize
...
@title = 'Welcome'
...
end

...
end

(Part of) the spec:

describe IndexController do

it 'should have a welcoming title' do
should assign_to(:title, :with=>'Welcome')
end

...
end

The backtrace when I run it:

ScriptError in 'IndexController should have a welcoming title'
No action was performed or declared.

Being new to this, I'm sure I'm goofing something up. Do you know
what I'm doing wrong? Thanks.

You must indicate which action is supposed to assign to @title :

describe IndexController do
describe :get => :index do
should_assign_to :title, :with => 'Welcome'
end
end

Cheers

That was it. Thank you for your help.
