Spring 运行update/delete命令时JUnit中的单元测试失败

我目前正在使用spring和hibernate开发Java中的API实现

我的模型包里有两张桌子

具有OneToMany映射的用户和用户详细信息

@Entity
public class User {
    private Long id;
    private String userId;
    private Set<UserDetail> userDetails;

    @OneToMany(cascade = CascadeType.ALL, orphanRemoval = true, mappedBy = "user")
    public Set<UserDetail> getUserDetails() {
        return userDetails;
    }

    public void setUserDetail(Set<UserDetail> userDetails) {
        this.userDetails = userDetails;
    }
}

@Entity
public class User {
    private Long id;
    private String key;
    private String value;
    private User user;

    @ManyToOne
    @JoinColumn(name = "USER_ID", nullable = false)
    public User getUser() {
        return user;
    }

    public void setUser(User user) {
        this.user = user;
    }
}

我编写了Junit测试用例来测试用户UserDetails的添加和删除，我的addUserDetail正常工作，但是当我调用delete时，更改没有反映出来，并且失败了

下面是我的测试用例

@Test
public void testDeletUserDetail() throws Exception {
    //GIVEN
    String userId = client.newUser().call(getCreateUserRequest()).getId();
    client.newAddUserDetail().call(getAddUserDetailRequest(userId, "key1", "value1"));
    client.newAddUserDetail().call(getAddUserDetailRequest(userId, "key2", "value2"));

    //WHEN
    client.newDeteteUserDetail().call(getDeleteUserDetailRequest(userId, "key2"));

    //THEN
    List<UserDetail> userDetails = client.newGetUserDetail().call(getGetUserDetailRequest(userId));
    assertEquals(userDetails.size(), 1);  // This check fails and says it has a size of 2 instead of 1.
}

所有存储库都扩展了JpaRepository

谁能解释一下如何回避这个问题

任何帮助都将不胜感激

似乎您的测试对象可能有多个用户详细信息；第一个测试解决了这个问题，第二个没有。您是否尝试打印出这些对象？返回的对象有两个条目，但它应该只有一个带有key=“key1”的条目，因为前面的delete命令已删除了一个条目@uwealn或者您可能有其他单元测试在处理数据？由于它们是以不可预测的顺序执行的，您是否确保每个都有干净的环境（干净的数据库等）？它由@Transaction注释，因此所有更改都会在测试完成后恢复，有许多测试，当我尝试在数据库上调用SELECT afer DELETE操作时，会发生此特定实例。

@Test
public void testDeletUserDetail() throws Exception {
    //GIVEN
    String userId = client.newUser().call(getCreateUserRequest()).getId();
    client.newAddUserDetail().call(getAddUserDetailRequest(userId, "key1", "value1"));
    client.newAddUserDetail().call(getAddUserDetailRequest(userId, "key2", "value2"));

    //WHEN
    client.newDeteteUserDetail().call(getDeleteUserDetailRequest(userId, "key2"));

    //THEN
    List<UserDetail> userDetails = client.newGetUserDetail().call(getGetUserDetailRequest(userId));
    assertEquals(userDetails.size(), 1);  // This check fails and says it has a size of 2 instead of 1.
