问答平台（8），单元测试

Spring Boot Testing

- 依赖：spring-boot-starter-test
- 包括：Junit、Spring Test、AssertJ、...

Test Case

- 要求：保证测试方法的独立性。
- 步骤：初始化数据、执行测试代码、验证测试结果、清理测试数据。
- 常用注解：@BeforeClass、@AfterClass、@Before、@After

测试类

• SpringBootTests: 新增

  @RunWith(SpringRunner.class)
  @SpringBootTest
  @ContextConfiguration(classes = CommunityApplication.class)
  public class SpringBootTests {
  
      @Autowired
      private DiscussPostService discussPostService;
  
      private DiscussPost data;
  
      @BeforeClass
      public static void beforeClass() {
          System.out.println("beforeClass");
      }
  
      @AfterClass
      public static void afterClass() {
          System.out.println("afterClass");
      }
  
      @Before
      public void before() {
          System.out.println("before");
  
          // 初始化测试数据
          data = new DiscussPost();
          data.setUserId(111);
          data.setTitle("Test title");
          data.setContent("Test content");
          data.setCreateTime(new Date());
          discussPostService.addDiscussPost(data);
      }
  
      @After
      public void after() {
          System.out.println("after");
  
          // 删除测试数据（拉黑帖子）
          discussPostService.updateStatus(data.getId(), 2);
      }
  
      @Test
      public void test1() {
          System.out.println("test1");
      }
  
      @Test
      public void test2() {
          System.out.println("test2");
      }
  
      @Test
      public void testFindById() {
          DiscussPost post = discussPostService.findDiscussPostById(data.getId());
          Assert.assertNotNull(post);
          Assert.assertEquals(data.getTitle(), post.getTitle());
          Assert.assertEquals(data.getContent(), post.getContent());
      }
  
      @Test
      public void testUpdateScore() {
          int rows = discussPostService.updateScore(data.getId(), 2000.00);
          Assert.assertEquals(1, rows);
  
          DiscussPost post = discussPostService.findDiscussPostById(data.getId());
          Assert.assertEquals(2000.00, post.getScore(), 2);
      }
  }
