Falando sobre cucumber!

“BDD outside in” em 2011

Bom e velho cucumber

Accessing website with true credentials
When I am on the login page
And I fill in "email" with "bla@email.com"
And I fill in "password" with "qwerty"
And I click button "Login"
Then I should see "Olá, bla@email.com"

smell gerado pelo web_steps.rb

+1 Camada de abstração
Mais código para manter

Clientes
Duplicando código em linguagem natural

esperam LER a
especiﬁcação
Clientes não
querem escrever testes!

Alcançando Valor com
Cucumber
Acessing website with true
credentials:
When I am on the login page
And I use my credentials
Then I should see a welcome
message

Manutenção continuou um
saco!
Duplicando
rspecs & cucumber
steps
Refactoring não é
perfeito
Cada vez menos testes
de aceitação com
cucumber
