[Jython-dev] jython20a1 regression test from py2.0
|
From: Ype K. <yk...@xs...> - 2000-11-28 21:11:04

Hello Jythoners,
First a question just out of curiosity.
Why was the 'p' dropped from the name JPython?
Where has Monty's flying circus gone?
Ok. A bit more serious now. I downloaded 20a1 and
tried to run the regression tests from python 2.0.
This worked to some extent after "adapting" the main program
regrtest.py to some modules not available in java.
Below is the summary of the test output.
I suppose you have done sth. like this yourself.
Still, would you be interested in more details?
Does this make any sense? If so, can I suggest to
include the regression test in the distribution of Jython?
The details (terse):
Slightly modified regrtest.py from python2.0 Lib/test
running under jython20a1 running under Blackdown java 1.2.2 for powerpc
with 60Mb of memory (the vm fails with a segfault at the default 30Mb
during a finalize, so I concluded the garbage collector is not yet
completely sane.)
All this running under Suse Linux 6.4 (kernel 2.2.14 with some additions).
I copied the files from python2.0/Lib/test/*.py to a separate directory
and ran jython regrtest.py. The output ends ao. with the following:
16 tests OK.
11 tests failed:
test_opcodes
test_operations
test_StringIO
test_class
test_format
test_longexp
test_pow
test_socked
test_ucn
test_unicode
test_unicodedata
80 tests skipped
The failing test_opcodes and test_class are not surprising, the fact that
they were not skipped is puzzling me. I have not read into the details.
Kind regards,
Ype
P.S. I had to manually patch the indentation of the modified parts a bit,
probably because of my tab setting (4) in vi. I hope I got it all right,
it might fail the syntax checker now.
Here is the modified regrtest.py:
(I should learn how to use diff and just send the patch, just a
handful of changes were needed.)
#! /usr/bin/env python
"""Regression test.
This will find all modules whose name is "test_*" in the test
directory, and run them. Various command line options provide
additional facilities.
Command line options:
-v: verbose -- run tests in verbose mode with output to stdout
-q: quiet -- don't print anything except if a test fails
-g: generate -- write the output file for a test instead of comparing it
-x: exclude -- arguments are tests to *exclude*
-s: single -- run only a single test (see below)
-r: random -- randomize test execution order
-l: findleaks -- if GC is available detect tests that leak memory
--have-resources -- run tests that require large resources (time/space)
If non-option arguments are present, they are names for tests to run,
unless -x is given, in which case they are names for tests not to run.
If no test names are given, all tests are run.
-v is incompatible with -g and does not compare test output files.
-s means to run only a single test and exit. This is useful when Purifying
the Python interpreter. The file /tmp/pynexttest is read to find the next
test to run. If this file is missing, the first test_*.py file in testdir or
on the command line is used. (actually tempfile.gettempdir() is used instead
of /tmp).

specify testdir; if it's omitted, the directory containing the
