@Test public void testListUser() { List<User> userList = UserMapper.list(); userList.Stream().ForEach(user ->{ System.out.println(User); }); }\

你的测试方法中，你想要测试的是`listUser`方法。在该方法中，你调用了`UserMapper.list()`方法来获取用户列表，并使用`forEach`方法遍历列表中的每个用户对象，并打印出用户的信息。

然而，我注意到你在遍历时使用了错误的变量名。你应该使用`user`而不是`User`来引用每个用户对象。因此，你的代码应该更改为：

@Test
public void testListUser() {
    List<User> userList = UserMapper.list();
    userList.stream().forEach(user -> {
        System.out.println(user);
    });
}

这样，你就可以正确地打印出每个用户对象的信息了。
