springboot单元测试

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)

2、常见错误

1）、java.lang.IllegalStateException Unable to find a @SpringBootConfiguration代码报错
