GHC Test framework

GHC includes a comprehensive testsuite for catching any regressions.

The testsuite relies primarily on GNU Make and Python. Any version >= 2.5.2 will do although avoid Python 2.6.1 as the testsuite tickles a bug in one of the included libraries.

If you have not checked out the testsuite, first run:

$ ./sync-all --testsuite get

If you just want to run the whole testsuite, then in the root of the GHC tree, typing:

$ make test

will do a run in "fast" mode (which gives an idea whether there are major problems), or

$ make fulltest

will do a full testsuite run (more thorough, but takes a lot longer). You should expect that there are no test case failures for the "fast" mode as as that is a quality level that all GHC developers are expected to maintain when they check in code. There will usually be some test case failures for the full testsuite run though.
