[英]Error when running JUnit 5 tests in IntelliJ but not on the command line
当我尝试在IntelliJ中运行简单的JUnit 5测试时,报告以下错误:

我正在使用Intellij v2017.1.2。
当我从命令行运行测试时,没有错误报告。
我见过各种文章报告了不同版本IntelliJ的类似问题,但建议的解决方案无济于事。
《 JUnit用户指南》建议使用2017.3或更高版本。
IntelliJ IDEA在IDEA 2017.3之前的版本捆绑了JUnit 5的特定版本。因此,如果您要使用JUnit Jupiter的较新版本,则由于版本冲突,IDE中的测试执行可能会失败。
