'Unable to load a Suite class' while running ScalaTest in IntelliJ
我今天在Intellij中运行一个简单的TestKit测试时遇到了一些问题。 测试针对Scala代码(我具有Intellij的Scala插件),并且基于Ray Roestenburg的示例。
Intellij项目是使用" Maven模块"创建的,然后我将所有依赖项添加到该项目并创建了我的项目。 测试位于以下位置:
ActorBlast/src/test/scala/basicTest.scala
我基本上是在测试上"右键单击",然后选择"运行"。 我得到的是以下错误:
"C:\Program Files\Java\jdk1.7.0_25\bin\java" -Didea.launcher.port=7540...
Testing started at 2:29 PM ...

我不知道这意味着什么。 我已经做了很多搜索,但似乎找不到答案。 请注意,跑步者抱怨找不到的课程是我要测试/运行的课程。 basicTest.scala看起来像这样:

对于我为什么收到此错误的任何帮助,将不胜感激。
运行构建项目-当我尝试解决另一个问题时,它帮助我解决了当我清除Cache IDEA :)时可能发生的问题。
这就是我解决相同异常的方法:
1 | --> Right click on your project folder in IDE: |
1 2 3 | --> Click Add Framework Support --> Then Check Scala --> Click OK |
您需要设置Scala SDK。
1.)通常,intelliJ会在编辑器的右上角显示一条消息来询问您
2)您可以按照https://www.jetbrains.com/help/idea/discover-intellij-idea-for-scala.html上的说明自己进行操作

正确配置模块后,我摆脱了错误。
最近,当我尝试使用IntelliJ IDEA 2018(社区版)在继承的Scala项目中运行测试时,发生了此问题。以下步骤可帮助我解决此问题:
Output path: /home/rustam/IdeaProjects/{project}/{module}/target/scala-2.12/classes
Test output path: /home/rustam/IdeaProjects/{project}/{module}/target/scala-2.12/test-classes
如果使用IntelliJ运行scalatest,请确保类路径正确。例如:
1 | /dummyApp |
