Pytest-check assert método de erros sem bloqueio

Na véspera do início do curso " Python QA Engineer " , uma tradução de material útil foi preparada para os futuros alunos e todos os interessados ​​no tema dos testes.



Também o convidamos a assistir a uma aula de demonstração sobre o tópico "Carreira de controle de qualidade".









Há muito debate na comunidade de testes sobre quantas declarações devem estar em um teste de IU automatizado. Algumas pessoas acham que deveria haver uma assert por teste, ou seja, cada teste deveria verificar apenas um elemento. Outros ficam muito felizes com o fato de seu teste verificar vários itens de uma vez. 





Seja qual for a abordagem que você escolher, acho que é seguro dizer que os testes devem permanecer claros, concisos, legíveis e, claro, devem ser fáceis de manter. Pessoalmente, não tenho problemas com várias afirmações em um teste, pois estou me concentrando em uma área funcional.





Por exemplo, vamos pegar um formulário de registro:
