1.IDEA安装TestNG

若IDEA已经安装TestNG的插件，显示如下

若没有，则搜索TestNG，进行下载

2.创建单元测试方法

1.打开需要进行单元测试的方法，选择类名，点击Alt+Enter键，选择Create Test

第一次创建单元测试方法，可能会提示“TestNG library not found In the module”，是因为没有在pom.xml文件中，写入TestNG插件的依赖，点击下图的“Fix”按钮，即可自动添加



setUp/@Before:创建@Before方法
tearDown/@After:创建@After方法
Show inherited methods：为父类的方法创建单元测试

2.规范单元测试的存放路径

output directory：${SOURCEPATH}/../../test/java/${PACKAGE}/${FILENAME}

因为Springboot框架的mapper文件放在了scm-bms-starter下面，将Controller层的单元测试方法放在scm-bms-web下，加载mapper文件失败，所以，将test方法转移到scm-bms-starter

package com.gw.scm.bms.web.controller;

import com.gw.scm.bms.BmsApplication;
import com.gw.scm.bms.commons.entity.BmsAccurateBomUpdateParamsEntity;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.boot.test.web.client.TestRestTemplate;
import org.springframework.http.ResponseEntity;
import org.springframework.test.context.testng.AbstractTestNGSpringContextTests;
import org.testng.annotations.Test;

@SpringBootTest(classes = {BmsApplication.class}, properties = {"classpath:*.yml", "classpath:*.xml"}, webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public class BmsAccurateBomControllerTest extends AbstractTestNGSpringContextTests {

    @Autowired
    private TestRestTemplate restTemplate;

    @Test
    public void testCreate() {

        BmsAccurateBomUpdateParamsEntity model = new BmsAccurateBomUpdateParamsEntity();
        model.setVehicleMaterialId(12L);
        model.setMaterialId(112L);

        ResponseEntity<String> entity = this.restTemplate.postForEntity("/BmsAccurateBom/create", model, String.class);
        System.out.println(entity.getBody());
    }
}
