篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了记Spring5集成TestNG进行单元测试的采坑经历相关的知识，希望对你有一定的参考价值。
TestNG是一款优秀的单元测试工具，和JUinit相比有不少有点，本文不做赘述。本文主要是对自己在配置过程中遇到的问题进行记录，也算是自己的经验积累，也希望有这方面经验的朋友不吝赐教。
一、版本
1、spring 5.0.2.RELEASE
2、TestNG 6.8.7
<dependency>
<groupId>org.testng</groupId>
<artifactId>testng</artifactId>
<version>6.8.7</version>
<scope>test</scope>
</dependency>3、开始踩坑
3.1
使用在spring中集成TestNG，单元测试类主要是要继承两个类
AbstractTestNGSpringContextTests ， AbstractTransactionalTestNGSpringContextTests。先说明继承这个类AbstractTestNGSpringContextTests 的情况
@ContextConfiguration("classpath:applicationContext.xml")
public class RoleServiceTest extends AbstractTestNGSpringContextTests
@Autowired
RoleService roleService;
@Test
public void testFindAll()
Assert.assertEquals(roleService.findAll().size(),3);
这样是没有问题的。下面说说继承 AbstractTransactionalTestNGSpringContextTests 这个类的情况。代码如下：
@ContextConfiguration("classpath:applicationContext.xml")
public class RoleServiceTransctionalTest extends AbstractTransactionalTestNGSpringContextTests
@Test
public void testFindAll()
Assert.assertEquals(JdbcTestUtils.countRowsInTable(this.jdbcTemplate,"sys_role"),3);
出现如下错误：

3.2 找不到 SessionCookieConfig 类错误
出现这个错误的原因的下面的这个包版本太低导致的，这个类在3.1及以上的版本中才有。
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>2.5</version>
<scope>provided</scope>
</dependency>3.2 spring-test的版本问题
还有的错误是 spring-test5+的包和TestNG包的匹配有问题，换成spring-test4+的版本就可以了
3.3 TestNG的版本问题
如果你的Spring5的版本比较高，尽量采用TestNG的高版本，推荐6.11 或者 7.1.0版本。
3.4 testng 与 com.springsource.org.testng
在官方的网站上，有这两个包，建议使用 com.springsource.org.testng 这是专门为 spring开发的，匹配性要好一些。
<dependency>
<groupId>org.testng</groupId>
<artifactId>testng</artifactId>
<version>6.8.7</version>
<scope>test</scope>
</dependency><dependency>
<groupId>org.testng</groupId>
<artifactId>com.springsource.org.testng</artifactId>
<version>6.5.2</version>
</dependency>昨天还遇到了好多坑，今天没有重现，也没有截图
