Mock of regular methods (functions and procedures)

[vampirsoft]

It would be nice to be able to mock regular methods (functions and procedures). This will allow you to intercept, for example, functions from the Winapi.Windows module, which will make testing much easier.

Example

type
  TSaveDC = function SaveDC(DC: HDC): Integer; stdcall;

const SaveDCMock = TMock<TSaveDC>.Create(Winapi.Windows.SaveDC);

SaveDCMock
  .Setup
  .WillReturn(9)
  .When(It0.IsEqualTo<HDC>(199));
SaveDCMock
  .Setup
  .Expect
  .One
  .When(It0.IsEqualTo<HDC>(199));

const Index = Winapi.Windows.SaveDC(119);

SaveDCMock.Verify // Error, because invalid param
Assert.AreEqual(9, Index);
