Jython is an implementation of the high-level, dynamic, object-oriented
language Python written in 100% Pure Java, and seamlessly integrated with
the Java platform. It thus allows you to run Python on any Java platform.

"""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
-w: verbose2 -- re-run failed tests in verbose mode
-q: quiet -- don't print anything except if a test fails
-x: exclude -- arguments are tests to *exclude*
-s: single -- run only a single test (see below)
-S: slow -- print the slowest 10 tests
-r: random -- randomize test execution order
-m: memo -- save results to file
-j: junit-xml -- save results as JUnit XML to files in directory
-f: fromfile -- read names of tests to run from a file (see below)
-l: findleaks -- if GC is available detect tests that leak memory
-u: use -- specify which special resource intensive tests to run
-h: help -- print this text and exit
-t: threshold -- call gc.set_threshold(N)
-T: coverage -- turn on code coverage using the trace module
-D: coverdir -- Directory where coverage files are put
-N: nocoverdir -- Put coverage files alongside modules
-L: runleaks -- run the leaks(1) command just before exit
-R: huntrleaks -- search for reference leaks (needs debug build, v. slow)
-M: memlimit -- run very large memory-consuming tests
-e: expected -- run only tests that are expected to run and pass
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.
-T turns on code coverage tracing with the trace module.
-D specifies the directory where coverage files are put.
-N Put coverage files alongside modules.
-s means to run only a single test and exit. This is useful when
doing memory analysis on the Python interpreter (which tend to consume
too many resources to run the full regression test non-stop). 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).
-f reads the names of tests from the file given as f's argument, one
or more test names per line. Whitespace is ignored. Blank lines and
lines beginning with '#' are ignored. This is especially useful for
whittling down failures involving interactions among tests.
-L causes the leaks(1) command to be run just before exit if it exists.
leaks(1) is available on Mac OS X and presumably on some other
FreeBSD-derived systems.
-R runs each test several times and examines sys.gettotalrefcount() to
see if the test appears to be leaking references. The argument should
be of the form stab:run:fname where 'stab' is the number of times the
test is run to let gettotalrefcount settle down, 'run' is the number
of times further it is run and 'fname' is the name of the file the
reports are written to. These parameters all have defaults (5, 4 and
"reflog.txt" respectively), so the minimal invocation is '-R ::'.
-M runs tests that require an exorbitant amount of memory. These tests
typically try to ascertain containers keep working when containing more than
2 billion objects, which only works on 64-bit systems. There are also some
tests that try to exhaust the address space of the process, which only makes
sense on 32-bit systems with at least 2Gb of memory. The passed-in memlimit,
which is a string in the form of '2.5Gb', determines howmuch memory the
tests will limit themselves to (but they may go slightly over.) The number
shouldn't be more memory than the machine has (including swap memory). You
should also keep in mind that swap memory is generally much, much slower
than RAM, and setting memlimit to all available RAM or higher will heavily
tax the machine. On the other hand, it is no use running these tests with a
limit of less than 2.5Gb, and many require more than 20Gb. Tests that expect
to use more than memlimit memory will be skipped. The big-memory tests
generally run very, very long.
-u is used to specify which special resource intensive tests to run,
such as those requiring large file support or network connectivity.
The argument is a comma-separated list of words indicating the
resources to test. Currently only the following are defined:
all - Enable all special resources.
audio - Tests that use the audio device. (There are known
cases of broken audio drivers that can crash Python or
even the Linux kernel.)
curses - Tests that use curses and will modify the terminal's
state and output modes.
largefile - It is okay to run some test that may create huge
files. These tests can take a long time and may
consume >2GB of disk space temporarily.
network - It is okay to run tests that use external network
resource, e.g. testing SSL support for sockets.
bsddb - It is okay to run the bsddb testsuite, which takes
a long time to complete.
decimal - Test the decimal module against a large suite that
verifies compliance with standards.
compiler - Test the compiler package by compiling all the source
in the standard library and test suite. This takes
a long time. Enabling this resource also allows
test_tokenize to verify round-trip lexing on every
file in the test library.
subprocess Run all tests for the subprocess module.
urlfetch - It is okay to download files required on testing.
To enable all resources except one, use '-uall,-'. For
example, to run all the tests except for the bsddb tests, give the
option '-uall,-bsddb'.
