如何使IntelliJ Scala插件运行单元测试，或者如何告诉IntelliJ文件是单元测试代码？

Question

In IntelliJ/Scala plugin, how can I run the Scala test code?

class TestFile extends FunSuite with BeforeAndAfter {
  test ("simple") {

I'm not sure exactly what happened, but I remember IntelliJ/Scala plugin automatically showed me a "run" menu with the right click, but I see nothing about the run menu. Is there any setup change to teach this file is Scala test file that can be executed?

Answer 1

Find the directory where all your tests are (if you are using Maven directory structure that would be src/test/scala) right click on it and choose "Mark directory as"-> "Test Sources Root". This would tell IntelliJ that the directory contains test and would make it offer to run tests in the right click menu of files

Answer 2

Right click on the source (especially on test class name or test name) opens up a menu that shows the run menu.
