À medida que nosso site cresce, leva cada vez mais tempo para rodar todos os nossos testes funcionais. Se isso continuar, o perigo é que vamos parar de nos preocupar com isso.
Em vez de deixar isso acontecer, podemos automatizar a execução dos testes funcionais configurando a “integração contínua” ou CI. Dessa forma, no desenvolvimento diário, podemos simplesmente executar o FT em que estamos trabalhando naquele momento e contar com a CI para executar todos os outros testes automaticamente e nos avisar se acidentalmente quebramos alguma coisa.
Os testes unitários devem permanecer rápidos o suficiente para que possamos continuar executando o conjunto completo localmente, a cada poucos segundos.
Observação
A integração contínua é outra prática que ficou famosa com o movimento de programação extrema (XP) de Kent Beck nos anos 90.
Como veremos, uma das grandes frustrações da configuração da CI é que o ciclo de feedback é muito mais lento do que trabalhar localmente. À medida que avançamos, vamos procurar maneiras de otimizar isso onde for possível.
Durante a depuração, também abordaremos o tema da reprodutibilidade. A ideia é que possamos reproduzir os comportamentos do nosso ambiente de CI localmente, da mesma forma que tentamos tornar nossos ambientes de produção e desenvolvimento o mais semelhantes possível.
CI em fluxos ...
