Great! I wanted something like this over the weekend. (Have you been 
borrowing Guido's time machine?)

N.B. If you look at the implementation of testall.py (at least for 2.2.2) 
it's just a hack which fiddles with sys.argv and then calls into 
test.regrtest (I mention this because regrtest.py has different output 
formating features which look much nicer than the verbose output of

That's interesting - Which platform and ObjSpace were you using?

When I tried this weekend with TrivialObjSpace under Python 2.2.2 on Win98 
the results were encouraging - most of the tests passed (eventually). 

One MAJOR caveat on that issue is that I had to edit regrtest.py to get it 
to work. Out of the box all the tests failed miserably with "Module Not 
Found Errors". regrtest.py assumes that tests are in test_???.py files in 
the current package level (Lib/test, but the level is implicit). However, 
when the pypy interpreter runs an import, the import runs local in the 
Lib/pypy/interpreter package - no test_??? files are found.

Additionally, when testing, an "import test" opens the "test" submodule of 

If you delete/rename the test directory, and edit regrtest.py such that it 
does an absolute import:

Change: the_module = __import__(test, globals(), locals(), [])
to: the_module = __import__("test", globals(), locals(), [test])

then testall/regrtest is happy. 

(No, I don't think this is a long-term solution to the problem ...)
