Why should_receive behaves differently

Testing RSpec
1

Hi friends

in my rspec_controller

1]@user.articles.should_receive(:find_by_id).with(‘1’).and_return(@article)

get :show,:id => 1

in above example 1 if i mention get :show, :id => 1 below the
schould_receive
it is working fine

but
2]get :show,:id => 1
@user.articles.should_receive(:find_by_id).with(‘1’).and_return(@article)

if i mention in the above way it is raising error!

Why ?
What is the reason?
Could any one explain please ?
Thanks in advance?

When you say “foo.should_receive(:bar)” you’re saying "foo should
receive bar sometime between now and the end of this example. The first
example, the “get” is doing something that causes @user.articles to
receive :find_by_id, but in the second example that’s already happened
before you set the expectation and does not happen again, so you get a
failure message.
