The prompt uses different paths depending on the OS

[Munsio]

Running on Windows we do give the prompt the windows style paths instead of the linux one which leads to an different prompt (not sure who it may impact).

  Given the following Java code file "src\main\java\com\eval\Plain.java" with package "com.eval", provide a test file for this code with JUnit 5 as a test framework.
  The tests should produce 100 percent code coverage and must compile.
  The response must contain only the test code and nothing else.

  ```java
  package com.eval;

  class Plain {
      static void plain() {
      }
  }
