MockMVC忽略了@Order注解的顺序，顺便说一下，按字母顺序命名它们，当第二个方法命名为test2_b时，该方法将成为第二个执行的方法，但在这种情况下，重命名为test2，它是最后一个执行的方法，尽管它应该是第二个执行的方法：

package com.javainuse.boot3security.test;

import org.junit.jupiter.api.Order;

import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.web.servlet.AutoConfigureMockMvc;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.boot.test.mock.mockito.MockBean;
import org.springframework.test.web.servlet.MockMvc;
import com.javainuse.boot3security.repository.DadosPessoaisRepository;

@SpringBootTest
@AutoConfigureMockMvc
class ClassTest {

    @Autowired
    MockMvc mockMvc;

    @MockBean
    private DadosPessoaisRepository dadosPessoaisRepository;

    @Order(1)
    @Test
    public void test1_a() throws Exception {
        System.out.println("Test1");    
    }

    @Order(2)
    @Test
    public void test2() throws Exception {
        System.out.println("Test2");        
    }

    @Order(3)
    @Test
    public void test3_c() throws Exception {
        System.out.println("Test3");        
    }   
    

    @Order(4)
    @Test
    public void test4_d() throws Exception {
        System.out.println("Test4");
    }
}

输出量：

Test1
Test3
Test4
Test2
