ion)
|
|
|
|
people_stub = mock "people"
|
|
people_stub.stub!(:each).and_yield(mock_user)
|
|
people_stub.stub!(:bad_method).and_raise(RuntimeError)
|
|
|
|
user_stub = mock_model("User", :id => 23, :username => "pat", :email =>
|
|
"pat@example.com")
|
|
|
|
my_instance.stub!(:msg).and_return(value)
