Unit Testing Mock library
« on: September 22, 2015, 03:30:38 pm »
Can anyone recommend a Mock library for Lazarus, I found Pascal Mock via google but doesn't seem to any active development so am not sure what else is out there.

Regards,

Stephen...

Look at this:

you can also search for "FPTest" and "FPCTest" in the forum for more information

I'm not sure FPTest has mock feature, as is FPCUnit.

Thanks for the reply guys,

Yes I'm actually using this unit and AFAIK it doesn't support Mock, is just unit testing

Did you really try Pascal Mock, and it doesn't work?

end;

@ jwdietrich No not yet, I haven't given it a go yet as I saw that there hadn't been any active development lately and I also wanted to see what others were using before I went down the path of trying it.

It still works, but requires little changes in the code. Somehow my FPC 3.1.1 is confused when it sees:
Code: [Select]
    //: Set return value
    procedure Returns(AValue: Variant); overload;
    procedure Returns(AValue: Pointer); overload;
    procedure Returns(AValue: IUnknown); overload;
    procedure Returns(AValue: TObject); overload;
And it decides that calls to this method with integer argument doesn't match any of them, while it should match the Variant one. Probably a compiler bug. It's trivial to typecast to Variant, however. There are only a few.

I use the newest Delphi project converter from my Lazarus trunk and greatly it knows that FPTest is DUnit compatible so it adds fptest automatically to the project dependency and it compiles just fine.

The test is not clean, though. 1 error 1 failure 5 warnings. No memory leak.

Attached is the modified archive.
