1、使用

1）配置

修改启动类所在的pom.xml增加单元测试，版本号注意与项目保持一致

<!--单元测试配置开始--><dependency><groupId>junit</groupId><artifactId>junit</artifactId></dependency><dependency><groupId>org.powermock</groupId><artifactId>powermock-module-junit4</artifactId><version>2.0.9</version><scope>test</scope></dependency><dependency><groupId>org.powermock</groupId><artifactId>powermock-api-mockito2</artifactId><version>2.0.9</version><scope>test</scope></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency><!--单元测试配置结束-->

2）写单元测试

单元测试的包名与启动类的要一致

3）websocket处理

@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.DEFINED_PORT)
