Not able to define behaviour for overloaded functions with different parameters. #141
Description
We recently upated the version of Delphi-Mocks we where using and with this version it looks like we can not define differen behaviour for overloaded functions.
IMockIntf = interface(IInvokable)
['{E473945B-D350-4535-A981-B66A5B58DA21}']
function Test(const Arg1: string): TArray<string>; overload;
function Test(const Arg1, Arg2: string): TArray<string>; overload;
function Test(const Arg1, Arg2, Arg3: string): TArray<string>; overload;
end;
Given this interface it was possible (and needed) to define a return value for alle 3 functions separatly.
FMock := TMock<IMockIntf>.Create;
FMock.Setup.WillReturn('Test1').When.Test(It0.IsAny<string>);
FMock.Setup.WillReturn('Test2').When.Test(It0.IsAny<string>, It1.IsAny<string>);
FMock.Setup.WillReturn('Test3').When.Test(It0.IsAny<string>, It1.IsAny<string>, It3.IsAny<string>);
And than test the behaviour
procedure TMyTestObject.Test1;
begin
var x := FMock.Instance.Test('A');
Assert.AreEqual('Test1', x);
end;
procedure TMyTestObject.Test2;
begin
var x := FMock.Instance.Test('A', 'B');
Assert.AreEqual('Test2', x);
end;
procedure TMyTestObject.Test3;
begin
var x := FMock.Instance.Test('A', 'B', 'C');
Assert.AreEqual('Test3', x);
end;
Unfortenatly with the latest version this is not working anymore. I looks like the Mock sees the Test functions as one and will not allow this:
EMockSetupException with message '[IMockIntf] already defines Will Return When for method [Test]'
If I use AllowRedefineBehaviorDefinitions := True I can define the behaviour, but than the function with 2 parameters returns the behaviour with 3 parameter 'Test3' and the function with 3 parameter raises an Access violation at address 00000000.
I used the latest version in combination with Delphi 11.3.
