+# Eleven Soft Backend Refactoring Test
+
+# Implementação de Testes Unitários para a API com projeto base Laravel no endpoint de usuários
+
+A implementação de métodos de teste unitário para o controlador de usuários (`UserController`) em uma aplicação Laravel. Os testes cobrem tanto cenários de sucesso quanto de falha, verificando os status codes apropriados para cada situação. (`UserControllerTest`)
+
+1. Instala e configura o projeto
+   
+`make install`
+
+2. Inicializa os containers
+   
+`make up`
+
+3. Renomeia o arquivo .env.example para .env
+   
+`make api-env`
+
+4. Gera a chave do Laravel e adiciona no arquivo .env
+   
+`make api-key`
+
+5. Executa os migrations e seeds
+   
+`make api-db`
+
+6. Executa para criar o cliente OAuth de autenticação de usuários via Passport
+   
+`make api-passport-generate`
+
+7. Executa para gerar a documentação Swagger
+   
+`make api-build-swagger`
+
+8. Executa a execução dos testes unitário de Feature
+   
+`make api-test-feature`
