[V3dot10] testing packages

[Ralph Johnson]

As I've said earlier, I want a system that lets us test packages so
that we can make sure that when we make a change to the base image, we
don't break anything.  I've built a system for running those kinds of
tests and you can see its results at
http://speedy.cs.uiuc.edu/~johnson/testResults/3.10alpha.7105.html

There are three issues that I'd like to raise.

First, there are lots of failing tests in the base image.  I think
most of these have to do with the Multiligual bugs that we fixed.  If
you start with the alpha.7105 image at
http://ftp.squeak.org/3.10alpha/  and file in Diego's fixes to
Multilingual at http://bugs.squeak.org/view.php?id=6520 then you
should be able to open the test runner, run all the tests, and get the
same results that I got.  Without Diego's fixes, running all tests
crashes the system.  Fixes are welcome!

Second, the more packages, the better.  Please suggest packages in PU
that I should use as test cases.  Packages without any tests aren't
that useful.  It is Ok for packages to have failing tests, but the
packages shouldn't crash or ask for input. See
http://wiki.squeak.org/squeak/5987     Note that GamesTests is a
package that is just tests, but it depends on a package of games so
when you load it, you load the games that it tests.  This is a good
way to provide tests when you don't want to always include the tests
with the application.

Third, I am not committed to this particular testing system.  It is
just something I threw together, and requires a bit of handholding to
keep going.  It probably won't run on anybody else's computer without
some tweaking.  If somebody else wants to write a better one, I would
be happy.  Otherwise I will eventually turn it into something more
stable.  Note that what I want is a way to take a proposed image and
see if it breaks any package.  The most important report is the one at
http://speedy.cs.uiuc.edu/~johnson/testResults/3.10alpha.7105.html
For details, you can always build your own image and use TestRunner,
so it is not so important that the testing system record the details.
