如何以漂亮的方式使用junit 5组测试(收集用户案例)

import org.junit.jupiter.api.*;
import org.junit.jupiter.params.ParameterizedTest;
import org.junit.jupiter.params.provider.CsvSource;
import static org.junit.jupiter.api.Assertions.*;

class UserServiceTest {

    private UserService userService;

    @BeforeEach
    void setUp() {
        userService = new UserService();
    }

    @DisplayName("测试用户注册功能")
    @ParameterizedTest(name = "{index} => 用户名={0}, 邮箱={1}, 预期结果={2}")
    @CsvSource({
        "user1, user1@example.com, true",
        "user2, invalid-email, false",
        "user3, user3@example.com, true"
    })
    void testRegisterUser(String username, String email, boolean expectedResult) {
        boolean result = userService.registerUser(username, email);
        assertEquals(expectedResult, result);
    }

    @DisplayName("测试用户登录功能")
    @Test
    void testLoginUser() {
        assertTrue(userService.loginUser("user1", "password1"));
        assertFalse(userService.loginUser("user1", "wrongpassword"));
    }

    @DisplayName("测试用户注销功能")
    @Test
    void testLogoutUser() {
        userService.logoutUser("user1");
        assertFalse(userService.isUserLoggedIn("user1"));
    }
}
