Re: [Pharo-project] MuTalk: Mutation Testing for Pharo Smalltalk

cool! Did you run MuTalk on pharo tests and did you find place where they could be improved?

Thanks Eliot Here this is the total pressure. Deadline yesterday and some for a week. So I hope that we will be back on track soon.

Hernan will probably join. May be Colin should join. We could have a nice momentum. - for the changes we would like to have something else than a chunk format because invoking the parser to know if we are manipulating a class definition is bad (with token at: 2 do that and token at: 3 do that). Again it will take time but we should have a good (why not 'exquise') infrastructure so that we extend and build new tool easily. Stef

We had a similar problem in squeaknos package, but just for some kind of classes.

There is no object representing workspace anymore. The same result will be if you add some method to some class, after image restart (without saving) there will be no such method. In this case you can use Recover Lost Changes tool to restore your method from .changes file. But in case of workspace you should *explicitely* save it into a file (using a window menu). And after image restart you will be able to restore it from that file.
