Working on Scala
When I am sending a code like def interpret(input: String): Option[String] =None or like smth in answer ut's working perfectly well and do compilation, but when I send my code with some realised functions, that works well on my computer - it sends an error message:
Test Suite Aborted
Exception encountered when invoking run on a nested suite - Unable to load a Suite class that was discovered in the runpath: SampleAssemblerInterpreterSuite

What is it?
