idea测试类加载不出来怎么办？

pom文件添加junit包，或者下载junit插件

为了帮助解决问题，能不能截图下ScoreTest测试类test1方法的方法体，或者直接截图所有的ScoreTest类？如果能提供一下项目目录结构更好。

把测试类的代码贴出来看看

 * 请把学生名与考试分数录入到Set中，并按分数显示前三名成绩学员的名字.怎么用Set实现?

应该是idea本身的问题，解决方法就是不用scanner输入或者

在你的Idea安装目录下的
D:\IntelliJ IDEA 2019.1.3\bin
里面的文件 idea64.exe.vmoptions追加以下内容：
-Deditable.java.test.console=true；

重启IDEA，重新执行单元测试类
