ArgumentError: Sequenz nicht registriert: E-Mail

Question

Ich bekomme diesen Fehler, wenn ich rspec: Sequenz nicht registriert: E-Mail.

Allerdings habe ich es in meiner factories.rb-Datei festgelegt. Irgendwelche Ideen, wie das zu beheben ist? Die App läuft gut.

Failures: 

    1) UsersController GET 'index' for signed-in-users should be successful 
    Failure/Error: @users << Factory(:user, :email => Factory.next(:email))

Setzen der Sequenz innerhalb des Blocks definieren?

FactoryGirl.define do 

    sequence :email { |n| "person-#{n}@example.com" } 

    factory :user do 
    name "Pavan Katepalli" 
    password "foobar" 
    password_confirmation "foobar" 
    email { FactoryGirl.generate(:email) } 
    end 

end
