[ANN] Test Coverage with Hapao

by Alexandre Bergel

Dear all, We are happy to release Hapao2 for Pharo. Ricard Jacas and Alejandro Infante put quite some work on Spy2 (an Ã¼ber cool profiling framework for Pharo) and Hapao2. Hapao2 is about assessing the test coverage of your code and is a major revamp of Hapao1, which was presented a couple of years ago by Vanessa. Hapao2 does not only list covered and uncovered methods, as most test coverage tool on Earth will do. Hapao gives a great visualization to easily navigate in your code, assess its complexity, and give you a great visual output telling its coverage. You need Roassal in your image: Gofer new smalltalkhubUser: 'ObjectProfile' project: 'Roassal2'; package: 'ConfigurationOfRoassal2'; load. (Smalltalk at: #ConfigurationOfRoassal2) load and you need S2py: MCHttpRepository location: 'http://smalltalkhub.com/mc/ObjectProfile/S2py/main' user: '' password: '' New entries will appear in the world menu: You can run the test coverage on : - the class classes you have modified, - on a particular - on a particular class category - on the last class categories you have modified - on the last packages you have modified Here is a portion of a large coverage: A technical description of Hapao may be found on http://bergel.eu/download/papers/Berg12c-HapaoSCP.pdf We are daily using Hapao to help us understand our tests.

Re: [Pharo-users] Recursive #printOn: renders the image unusable

by Johan Fabry

Hi all, for what itâs worth, I actually would prefer Object>>name to be removed. It does not make sense to me to be defined at that level, and whenever I define an Object subclass with a name instvar and accessors, I am surprised (luckily no longer worried) when I see that I am overriding name.

For infinitely zoomable interface, an old body of work and research on the possibilities is Pad++ [http://www.cs.umd.edu/hcil/pad++/] . Parcplace did some stuff too.
