Tipos de testes https://willianjusten.com.br/entendendo-testes-de-software/ • Teste de Unidade • Teste
de Integração/Service • Teste de UI/e2e • etc
Testes Unitários O teste unitário tem por objetivo testar a
menor parte testável do sistema (unidade), em geral, um método. Idealmente, o teste unitário é independente de outros testes, validando assim cada parte ou funcionalidade individualmente.
Respondendo algumas perguntas O que eu estou testando? O que
o método deveria fazer? Qual o seu atual retorno? O que eu espero que retorne?
