DESCRIPTION = """\
|
|
Run Python regression tests.
|
|
|
|
If no arguments or options are provided, finds all files matching
|
|
the pattern "test_*" in the Lib/test subdirectory and runs
|
|
them in alphabetical order (but see -M and -u, below, for exceptions).
|
|
|
|
For more rigorous testing, it is useful to use the following
|
|
command line:
|
|
|
|
python -E -Wd -m test [options] [test_name1 ...]
|
|
"""
|
|
|

EPILOG = """\
|
|
Additional option details:
|
|
|
|
-r randomizes test execution order. You can use --randseed=int to provide an
|
|
int seed value for the randomizer. The randseed value will be used
|
|
to set seeds for all random usages in tests
|
|
(including randomizing the tests order if -r is set).
|
|
By default we always set random seed, but do not randomize test order.
|
|
|
|
-s On the first invocation of regrtest using -s, the first test file found
|
|
or the first test file given on the command line is run, and the name of
|
|
the next test is recorded in a file named pynexttest. If run from the
|
|
Python build directory, pynexttest is located in the 'build' subdirectory,
|
|
otherwise it is located in tempfile.gettempdir(). On subsequent runs,
|
|
the test in pynexttest is run, and the next test is written to pynexttest.
|
|
When the last test has been run, pynexttest is deleted. In this way it
|
|
is possible to single step through the test files. This is useful when
|
|
doing memory analysis on the Python interpreter, which process tends to
|
|
consume too many resources to run the full regression test non-stop.
|
|
|
|
-S is used to continue running tests after an aborted run. It will
|
|
maintain the order a standard run (ie, this assumes -r is not used).
|
|
This is useful after the tests have prematurely stopped for some external
|
|
reason and you want to start running from where you left off rather
|
|
than starting from the beginning.
|
|
|
|
-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), and 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 how much 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.
|
|
|
|
none - Disable all special resources (this is the default).
|
|
|
|
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 >2 GiB of disk space temporarily.
|
|
|
|
network - It is okay to run tests that use external network
|
|
resource, e.g. testing SSL support for sockets.
|
|
|
|
decimal - Test the decimal module against a large suite that
|
|
verifies compliance with standards.
|
|
|
|
cpu - Used for certain CPU-heavy tests.
|
|
|
|
walltime - Long running but not CPU-bound tests.
|
|
|
|
subprocess Run all tests for the subprocess module.
|
|
|
|
urlfetch - It is okay to download files required on testing.
|
|
|
|
gui - Run tests that require a running GUI.
|
|
|
|
tzdata - Run tests that require timezone data.
|
|
|
|
To enable all resources except one, use '-uall,-<resource>'. For
|
|
example, to run all the tests except for the gui tests, give the
|
|
option '-uall,-gui'.
|
|
|
|
--matchfile filters tests using a text file, one pattern per line.
|
|
Pattern examples:
|
|
|
|
- test method: test_stat_attributes
|
|
- test class: FileTests
|
|
- test identifier: test_os.FileTests.test_stat_attributes
