При изучении тестирование наткнулся на плагин
Diffblue
, который пишет тесты.
Сам в тестировании пока-что ничего не понимаю, чтобы оценить результат. Прошу оценить работу
результат работы плагина.
Обычный сервис класс:
@Service
@Slf4j
public class ProductService {
@Autowired
private ProductRepository repo;
public List<Product> listAll(String keyword) {
if (keyword != null) {
log.info("Поиск продукта по ключевому слову {}", keyword);
return repo.search(keyword);
}
return repo.findAll();
}
public void save(Product product) {
if (product != null){
repo.save(product);
}else {
log.error("Продукт не может быть пустым!");
}
}
public Product get(Long id) {
if (repo.findById(id).isPresent()){
return repo.findById(id).get();
}
log.error("Продукт не найден");
return null;
}
public void delete(Long id) {
log.warn("Продукт по id {} удален", id);
repo.deleteById(id);
}
public List<Product> getAll(){
return repo.findAll();
}
}
тест:

assertSame(productList, actualListAllResult);
assertTrue(actualListAllResult.isEmpty());
verify(this.productRepository).search((String) any());
assertTrue(this.productService.getAll().isEmpty());
}
@Test
void testSave() {
Product product = new Product();
product.setPrice(10.0);
