No way to capture all method calls when parameters are required. about delphi-mocks HOT 5 CLOSED

It would seem libraries like Moq use the following syntax.

mock.Setup(x => x.DoSomething(It.IsAny<string>())).Returns((string s) => s.ToLower());

This is contrary to the fluent API. Also doesn't seem possible with the fluent API design.

Anyone have any thoughts on how this could be implemented?

It's not the best approach but you can realize something like this:

mockVisitor.Setup.Expect.Once.When.Visit(Is<IElement>.Any<IVisitor>)

IElement = T
IVisitor = U

The "Is.Any"-Function could return an object that implements "T" (IElement) and another interface like:

IParameterFilter<U> = interface
   ....
   function ParameterMatch(parameter: U): boolean;
 ...
end;

The class could look like:

TParameterFilter<T, U> = class(TVirtualInterface, IParameterFilter)
   ...
   function ParameterMatch(parameter: U): boolean;
   function Instance: T;
   ...
end;

The class should implement "T" via the virtual Interface class (so an instance of this class could be passed to the setup-Call of your method):

On finding a behavior, you could check if the behavior-parameter supports the filter-interface, execute it with the methods-parameter as parameter for "ParameterMatch" and if it returns true, use this behavior.

I hope it's clear what I mean.

Another idea for the syntax of the fluent API:
Is.Any.WhichSupports

In this way, the Is.Any-Returns the IParameterFilter-Interface directly an every call of IParameterFilter returns a "U" (IElement).
Unfortunately with this solution it's not possible to call "Is.Any" since Is.Any returns an IParameterFilter - not "T". So you need to write "Is.Any.All" or something like that.

Could you not handle it slightly differently, like the following:

mockVisitor.Setup.Expect.Once.WhenAny.Visit

When I need to test a method is called, I write this as

mockVisitor.Setup.ExpectExactly( 'Visit', 1)

from delphi-mocks.

Closing since we've not been able to implement this in any usable way.
