So you want to stub message to any instance of class. Right?

Conceptually, in Mocketry/StateSpecs way, it should looks like:

(Instance of: Something) stub askForName willReturn: 'new'.

or:

(Kind of: Something) stub askForName willReturn: 'new'.

But it will not really works. It will work only on instances which are already "stubbed".

Making it really transparent will require crazy magic underhood. And I am not sure that it is really possible.��

Because generally it should cover existing instances and not just newly created during test.��

And for simple case: to automatically stub new instances their classes should be stubbed with special constructors. But system do not know what exact class side messages are constructors.

So now you can just use simple mock which will be returned as simple stub from concrete constructor of your class:

some := Mock new.

some stub askForName: 'new'.

Something stub new willReturn: some.

I think it looks not not bad and no crazy magic is evolved. And of course you can replace mock with real instance if you want:

some := Something new.

some stub askForName: 'new'.

Something stub new willReturn: some.

Yes, but in that case you stub messages to the class itself. For your example it means:

Something stub askForName willReturn: 'new'.
Something��askForName��should be: 'new'

Thanks Denis, that did the trick.

But I thought that I can also mock at the class level (at least it was shown in the docs).

Hi Peter.

You should stub instance instead of class:
�� s := Something new.
�� s stub askFor...

Hi,

maybe I am missing something fundamental, because this seems like an obvious scenario

I have a class Something with two methods

Something>>askForName
^ UIManager default request: 'Name'

Something>>name
^ self askForName , ' suffix'

Now I want to mock out askForName, so I can run it automatically in tests...

I've tried just stubbing it...

SomethingTest>>testRenameStub
Something stub askForName willReturn: 'new'.
Something new name should be: 'new suffix'

however it still opens the window to ask for the name, so the original method is being called.

Right now I have to stub it with metalinks, which doesn't play well with some tools (hapao)

SomethingTest>>testRenameMeta
| link newName |
link := MetaLink new
metaObject: [ 'new' ];
control: #instead.
(Something >> #askForName) ast link: link.
[ newName := Something new name ]
ensure: [ link uninstall ].
self assert: newName equals: 'new suffix'

Thanks,
Peter
