3"""Regression test.
4
5This will find all modules whose name is "test_*" in the test
6directory, and run them. Various command line options provide
7additional facilities.
8
9Command line options:
10
11-v: verbose -- run tests in verbose mode with output to stdout
12-w: verbose2 -- re-run failed tests in verbose mode
13-q: quiet -- don't print anything except if a test fails
14-x: exclude -- arguments are tests to *exclude*
15-s: single -- run only a single test (see below)
16-S: slow -- print the slowest 10 tests
17-r: random -- randomize test execution order
18-f: fromfile -- read names of tests to run from a file (see below)
19-l: findleaks -- if GC is available detect tests that leak memory
20-u: use -- specify which special resource intensive tests to run
21-h: help -- print this text and exit
22-t: threshold -- call gc.set_threshold(N)
23-T: coverage -- turn on code coverage using the trace module
24-D: coverdir -- Directory where coverage files are put
25-N: nocoverdir -- Put coverage files alongside modules
26-L: runleaks -- run the leaks(1) command just before exit
27-R: huntrleaks -- search for reference leaks (needs debug build, v. slow)
28-M: memlimit -- run very large memory-consuming tests
29
30If non-option arguments are present, they are names for tests to run,
31unless -x is given, in which case they are names for tests not to run.
32If no test names are given, all tests are run.
33
34-T turns on code coverage tracing with the trace module.
35
36-D specifies the directory where coverage files are put.
37
38-N Put coverage files alongside modules.
39
40-s means to run only a single test and exit. This is useful when
41doing memory analysis on the Python interpreter (which tend to consume
42too many resources to run the full regression test non-stop). The
43file /tmp/pynexttest is read to find the next test to run. If this
44file is missing, the first test_*.py file in testdir or on the command
45line is used. (actually tempfile.gettempdir() is used instead of
46/tmp).
47
48-f reads the names of tests from the file given as f's argument, one
49or more test names per line. Whitespace is ignored. Blank lines and
50lines beginning with '#' are ignored. This is especially useful for
51whittling down failures involving interactions among tests.
52
53-L causes the leaks(1) command to be run just before exit if it exists.
54leaks(1) is available on Mac OS X and presumably on some other
55FreeBSD-derived systems.
56
57-R runs each test several times and examines sys.gettotalrefcount() to
58see if the test appears to be leaking references. The argument should
59be of the form stab:run:fname where 'stab' is the number of times the
60test is run to let gettotalrefcount settle down, 'run' is the number
61of times further it is run and 'fname' is the name of the file the
62reports are written to. These parameters all have defaults (5, 4 and
63"reflog.txt" respectively), so the minimal invocation is '-R ::'.
64
65-M runs tests that require an exorbitant amount of memory. These tests
66typically try to ascertain containers keep working when containing more than
672 billion objects, which only works on 64-bit systems. There are also some
68tests that try to exhaust the address space of the process, which only makes
69sense on 32-bit systems with at least 2Gb of memory. The passed-in memlimit,
70which is a string in the form of '2.5Gb', determines howmuch memory the
71tests will limit themselves to (but they may go slightly over.) The number
72shouldn't be more memory than the machine has (including swap memory). You
73should also keep in mind that swap memory is generally much, much slower
74than RAM, and setting memlimit to all available RAM or higher will heavily
75tax the machine. On the other hand, it is no use running these tests with a
76limit of less than 2.5Gb, and many require more than 20Gb. Tests that expect
77to use more than memlimit memory will be skipped. The big-memory tests
78generally run very, very long.
79
80-u is used to specify which special resource intensive tests to run,
81such as those requiring large file support or network connectivity.
82The argument is a comma-separated list of words indicating the
83resources to test. Currently only the following are defined:
84
85 all - Enable all special resources.
86
87 audio - Tests that use the audio device. (There are known
88 cases of broken audio drivers that can crash Python or
89 even the Linux kernel.)
90
91 curses - Tests that use curses and will modify the terminal's
92 state and output modes.
93
94 lib2to3 - Run the tests for 2to3 (They take a while.)
95
96 largefile - It is okay to run some test that may create huge
97 files. These tests can take a long time and may
98 consume >2GB of disk space temporarily.
99
100 network - It is okay to run tests that use external network
101 resource, e.g. testing SSL support for sockets.
102
103 bsddb - It is okay to run the bsddb testsuite, which takes
104 a long time to complete.
105
106 decimal - Test the decimal module against a large suite that
107 verifies compliance with standards.
108
109 compiler - Test the compiler package by compiling all the source
110 in the standard library and test suite. This takes
111 a long time. Enabling this resource also allows
112 test_tokenize to verify round-trip lexing on every
113 file in the test library.
114
115 subprocess Run all tests for the subprocess module.
116
117 urlfetch - It is okay to download files required on testing.
118
119To enable all resources except one, use '-uall,-<resource>'. For
120example, to run all the tests except for the bsddb tests, give the
121option '-uall,-bsddb'.
