一、添加测试类的依赖
在admin 模块中添加单元测试
将以下依赖添加到 admin 的 pom.xml 中
<!--测试类-->
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<scope>test</scope>
</dependency>
<!--测试类-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-test</artifactId>
<scope>test</scope>
</dependency>
<!--测试类-->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-test</artifactId>
<scope>test</scope>
</dependency>
二、编写测试类
在 src 目录下创建 test.java.MainTests 文件
import com.ruoyi.RuoYiApplication;
import com.ruoyi.activity.domain.Activity;
import com.ruoyi.activity.mapper.ActivityMapper;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;
import java.util.List;
@RunWith(SpringRunner.class)
@SpringBootTest(classes = RuoYiApplication.class)
public class MainTests {
@Autowired
private ActivityMapper activityMapper;
@Test
public void testSelectActivityById() {
Activity activity = activityMapper.selectActivityById(1);
System.out.println(activity);
}
@Test
public void testSelectActivityList() {
List<Activity> activityList = activityMapper.selectActivityList(new Activity());
System.out.println(activityList);
}
}
三、Spring Boot 加入websocket后，单元测试启动报错（javax.websocket.server.ServerContainer not available）
错误提示:
java.lang.IllegalStateException: Failed to load ApplicationContext
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘serverEndpointExporter’ defined in class path resource [com/zou/sell/config/WebSocketConfig.class]: Invocation of init method failed; nested exception is java.lang.IllegalStateException: javax.websocket.server.ServerContainer not available文章来源：https://www.toymoban.com/news/detail-808933.html
解决方案：
在springbootTest注解加入 webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT，我们在测试使用 websocket的时候需要启动一个完整的服务器，而使用这个注解就是说每次测试都会选用一个随即可用的端口模拟启动一个完整的服务器文章来源地址https://www.toymoban.com/news/detail-808933.html
@SpringBootTest(classes = RuoYiApplication.class,webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
