    • asserT

      public static void asserT​(java.lang.String s, java.lang.Boolean b) throws ScriptBasicException
      Throw an exception causing BASIC runtime error if the assertion fails. This can be used in the BASIC program to test preconditions and stop the execution of the BASIC program if the condition fails. For example you can write 
       assert("test that the parameter starts with the required prefix", startsWith(s,prefix))

      In the example above if the variable s starts with the string contained in the variable prefix then the execution of the BASIC program goes on, otherwise the function causes BASIC runtime error.

      Parameters:
      s - parameter
      b - parameter
      Throws:
      ScriptBasicException - in case of exception
