Spring Boot Mockito (二)

本文主要是介绍Spring Boot Mockito (二)，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

Spring Boot Mockito (二)

基于第一篇Spring Boot Mockito (一)
这篇文章主要是讲解Spring boot 与 Mockito 集成持久层接口层单元测试。

1. 引入数据库 h2及其依赖包

<dependency><groupId>com.h2database</groupId><artifactId>h2</artifactId><scope>runtime</scope>
</dependency>

2. 增加h2的属性配置 application.properties

spring.h2.console.enabled=truespring.jpa.show-sql=true
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.H2Dialect

3. 增加Order 的属性限制

public class Order {//...// 对Order增加注解@NotNull@NotBlank@Size(max = 50)@Column(length = 50)private String name;@NotNullprivate Double price;//...

4. 初始化数据

@Component
@RequiredArgsConstructor
public class InitData implements CommandLineRunner {private final OrderRepository orderRepository;@Overridepublic void run(String... args) throws Exception {loadOrderData();}private void loadOrderData() {if (orderRepository.count() == 0) {Order order1 = Order.builder().id(1001L).name("Moon chairs").price(58.0).createTime(LocalDateTime.of(2024, 04, 01, 22, 10, 10)).build();Order order2 = Order.builder().id(1002L).name("Outdoor canopy black coating").price(98.0).createTime(LocalDateTime.of(2024, 04, 01, 22, 10, 10)).build();Order order3 = Order.builder().id(1003L).name("Outdoor canopy silver coating").price(48.0).createTime(LocalDateTime.of(2024, 04, 01, 22, 10, 10)).build();orderRepository.save(order1);orderRepository.save(order2);orderRepository.save(order3);}}
}

5. 新建持久层单元测试

@DataJpaTest
@Import(InitData.class)
public class OrderRepositoryTest {@AutowiredOrderRepository orderRepository;@Testvoid test_findAllByNameLike() {List<Order> list = orderRepository.findAllByNameLike("%Outdoor%");assertEquals(2, list.size());}@Testvoid test_findAllByNameLike_Empty() {List<Order> list = orderRepository.findAllByNameLike("%Outdoor folding chair%");assertEquals(0, list.size());}@Testvoid test_findAllByPriceLessThan() {List<Order> list = orderRepository.findAllByPriceLessThan(50d);assertEquals(1, list.size());}@Testvoid test_findAllByPriceLessThan_Empty() {List<Order> list = orderRepository.findAllByPriceLessThan(10d);assertEquals(0, list.size());}@Testvoid test_saveOrder() {Order order4 = Order.builder().id(1004L).name("Outdoor folding chair").price(28.0).createTime(LocalDateTime.of(2024, 04, 01, 22, 10, 10)).build();orderRepository.save(order4);long count = orderRepository.count();assertEquals(4, count);}@Testvoid test_saveOrder_NameIsTooLong() {Order order4 = Order.builder().id(1004L).name("Outdoor folding chair Outdoor folding chair Outdoor folding chair Outdoor folding chair Outdoor folding chair").price(28.0).createTime(LocalDateTime.of(2024, 04, 01, 22, 10, 10)).build();order4 = orderRepository.save(order4);try {orderRepository.flush();fail("Name is null");} catch (ConstraintViolationException cve) {assertTrue(validate(cve, "size must be between 0 and 50", "name"));}}@Testvoid test_saveOrder_NameIsNull() {Order order4 = Order.builder().id(1004L).price(28.0).createTime(LocalDateTime.of(2024, 04, 01, 22, 10, 10)).build();try {order4 = orderRepository.save(order4);orderRepository.flush();fail("Name is null");} catch (ConstraintViolationException cve) {assertTrue(validate(cve, "must not be null", "name"));}}private boolean validate(ConstraintViolationException cve, String message, String fieldName) {return cve.getConstraintViolations().stream().anyMatch(e -> {boolean hasMessage = e.getMessage().contains(message);Iterator<Path.Node> itr = e.getPropertyPath().iterator();boolean matchedFieldName = false;while (itr.hasNext()) {Path.Node pNode = itr.next();matchedFieldName = pNode.getName().equals(fieldName);if (matchedFieldName) {break;}}return hasMessage && matchedFieldName;});}
}
