"""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.
|
|
|
|
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.
|
|
|
|
Options:
|
|
|
|
-h/--help -- print this text and exit
|
|
|
|
Verbosity
|
|
|
|
-v/--verbose -- run tests in verbose mode with output to stdout
|
|
-w/--verbose2 -- re-run failed tests in verbose mode
|
|
-d/--debug -- print traceback for failed tests
|
|
-q/--quiet -- no output unless one or more tests fail
|
|
-S/--slow -- print the slowest 10 tests
|
|
--header -- print header with interpreter info
|
|
|
|
Selecting tests
|
|
|
|
-r/--random -- randomize test execution order (see below)
|
|
--randseed -- pass a random seed to reproduce a previous random run
|
|
-f/--fromfile -- read names of tests to run from a file (see below)
|
|
-x/--exclude -- arguments are tests to *exclude*
|
|
-s/--single -- single step through a set of tests (see below)
|
|
-u/--use RES1,RES2,...
|
|
-- specify which special resource intensive tests to run
|
|
-M/--memlimit LIMIT
|
|
-- run very large memory-consuming tests
|
|
|
|
Special runs
|
|
|
|
-l/--findleaks -- if GC is available detect tests that leak memory
|
|
-L/--runleaks -- run the leaks(1) command just before exit
|
|
-R/--huntrleaks RUNCOUNTS
|
|
-- search for reference leaks (needs debug build, v. slow)
|
|
-T/--coverage -- turn on code coverage tracing using the trace module
|
|
-D/--coverdir DIRECTORY
|
|
-- Directory where coverage files are put
|
|
-N/--nocoverdir -- Put coverage files alongside modules
|
|
-t/--threshold THRESHOLD
|
|
-- call gc.set_threshold(THRESHOLD)
|
|
-n/--nowindows -- suppress error message boxes on Windows
|
|
|
|
|
|
Additional Option Details:
|
|
|
|
-r randomizes test execution order. You can use --randseed=int to provide a
|
|
int seed value for the randomizer; this is useful for reproducing troublesome
|
|
test orders.
|
|
|
|
-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).
|
|
|
|
-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 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.
|
|
|
|
decimal - Test the decimal module against a large suite that
|
|
verifies compliance with standards.
|
|
|
|
cpu - Used for certain CPU-heavy 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.
|
|
|
|
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'.
