I em not sure if it fits into philosophy of the picture. Reflectivity as well as living environmet is attribute of Pharo.

Can be. First version contains this, but I change it because connectors to external databases are used for more then persistency.

I did not finish reading all books yet :) Maybe this is a good question. What kind of services can Pharo provide over the network (or local sockets or pipes)? Zinc as HTTP for sure (somewhere I see HTTPS branch...or TLS implementation). WEB, REST and others are covered in Web development. VNC - through RemoteFrameBuffer. Databases (direct connection without using REST)? Repository and versioning (like Smalltalkhub - but I think it uses HTTP) CORBA? What about possibility to share objects (by cloning objects or by sending messages or by using proxy objects)? (Now I em not able to think about anything else much usefull :) - SSH, NTP, IMAP, nothing like this seems to be right job for Pharo - but who knows :)) > > > > "Output" is a bit too much like "Export".

The point was, that many people write tests as an afterthought... which means they have different means of getting feedback from the system (e.g. logging, running manually the code, etc.). In such situation they often end up testing already mostly working code, and thus the feedback from the tests is not as important, because you end up less digging up problems (since large portion were found and resolved during manual testing). > We could think about subclassing TestFailure and a way to hand information > to the TestFailure so that a nice String can be produced.

And while I could explicitly separate the two, if I do it all the time I don't see what's bad about having a convenience method.

Sure, there are 32 methods in the "asserting" protocol, however most of them are either opposites of one another "#assert: vs #deny:", or they provide some customization such has "#assert:description:", "#should:raise:" ... so if I count only meaningfully different methods the number 7 (not to mention that some of the methods are not even used).

If I could type less then I would be happier user, however currently I don't see a way how to make it more general (so I don't need to type) and more precise (it still understands context) at the same time. So going back to your earlier suggestion with the class... you imagine something like this? self assert: a equals: b strategy: CollectionHasExactlyTheSameElementsAsAnotherAtTheSamePosition where the method would have both the definition of the assertion and a way to nicely display it? (which could be of course delegated to other parties via composition, or maybe the test assertion could specify both independently) So my question is --- how to compare collections irrespective of type, and >> possibly of order? >> >> A) always convert the actual collection toanArray >> >> I don't think it is a good idea to provide tests fro general Collections > that first convert it to some specialized Collection class.

Providing selectors such as #assertCollection:equals: and similar just to get different description may not be the best idea, which leads to point 3 3. An easy way to extend printing/assertions/plugins; but what would that look like? Maybe #assert: a = b description: [ Diff collectionDiffBetween: a and: b ] or #assert: a equals: b strategy: CollectionHasExactlyTheSameElementsAsAnotherAtTheSamePosition or something else... Peter

Hello Mariano, thank you for your kind word of course I am one of the many contributors and UPBE is a collective effort. We dont have an image right now for UPBE and I think that the best way to approach this is to make a package for the Catalog Browser . This means you will be able to use UPBE examples to any image you have instead of being isolated to a different image. When this will happen I cant promise anything since our first priority is to make the documentation as up to date as possible. Currently we support Pharo 4 and 5 , with focus of course on Pharo 5. Obviously in the future the focus will continuously shift towards the latest version. So when we put the "Updated" to Pharo by Example, we mean business.
