Testing Levels (unit, functional group)

Video example:

See the full example in the demo application LevelUnits.dpr

Example of creating a module testing test from Delphi delivery.

1. Registration in multiple modules (System.pas & Math) in the same class.

unit SysDelphi;
interface
 uses   Math,
 TestMeType,TestMeLevelType ;
 type
  TTest_DelphiBorland=class
    // TestMeType System.pas
     class Procedure System_RM;// _RegisterMethod
     class Function System_TM( IMethod:IRunMethodParam):TTestResultParam;//_TestMethods
    // Test Math.pas
     class Procedure Math_RM;
     class Function  Math_TM( IMethod:IRunMethodParam):TTestResultParam;
  end;
