🧪 Implementar Camada de Testes

[Edwanderson]

Issue: 🧪 Implementar Camada de Testes

Descrição:

Implementar testes automatizados para garantir a qualidade do código e o correto funcionamento da API.

Sub-issues:

• [ ] 🧪 Criar testes para o ProductService
• [ ] 🧪 Criar testes para o ProductController
• [ ] 🧪 Configurar o ambiente de testes com JUnit e Mockito

Código de exemplo para testes:

import static org.mockito.Mockito.*;
import static org.junit.jupiter.api.Assertions.*;
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Test;
import org.mockito.InjectMocks;
import org.mockito.Mock;
import org.mockito.MockitoAnnotations;

public class ProductServiceTest {

    @InjectMocks
    private ProductService productService;

    @Mock
    private ProductRepository productRepository;

    private Product product;

    @BeforeEach
    public void setUp() {
        MockitoAnnotations.openMocks(this);
        product = new Product();
        product.setId(1L);
        product.setName("Product Name");
        product.setPrice(100.00);
    }

    @Test
    public void testCreateProduct() {
        when(productRepository.save(any(Product.class))).thenReturn(product);
        Product createdProduct = productService.createProduct(product);
        assertNotNull(createdProduct);
        assertEquals(product.getId(), createdProduct.getId());
    }

    @Test
    public void testGetProductById() {
        when(productRepository.findById(1L)).thenReturn(Optional.of(product));
        Product foundProduct = productService.getProductById(1L);
        assertNotNull(foundProduct);
        assertEquals(product.getId(), foundProduct.getId());
    }
}
