| 3 | """Regression test. |
| 4 | |
| 5 | This will find all modules whose name is "test_*" in the test |
| 6 | directory, and run them. Various command line options provide |
| 7 | additional facilities. |
| 8 | |
| 9 | Command line options: |
| 10 | |
| 11 | -v: verbose -- run tests in verbose mode with output to stdout |
| 12 | -q: quiet -- don't print anything except if a test fails |
| 13 | -g: generate -- write the output file for a test instead of comparing it |
| 14 | -x: exclude -- arguments are tests to *exclude* |
| 15 | -s: single -- run only a single test (see below) |
| 16 | -r: random -- randomize test execution order |
| 17 | -f: fromfile -- read names of tests to run from a file (see below) |
| 18 | -l: findleaks -- if GC is available detect tests that leak memory |
| 19 | -u: use -- specify which special resource intensive tests to run |
| 20 | -h: help -- print this text and exit |
| 21 | -t: threshold -- call gc.set_threshold(N) |
| 22 | -T: coverage -- turn on code coverage using the trace module |
| 23 | -D: coverdir -- Directory where coverage files are put |
| 24 | -N: nocoverdir -- Put coverage files alongside modules |
| 25 | -L: runleaks -- run the leaks(1) command just before exit |
| 26 | -R: huntrleaks -- search for reference leaks (needs debug build, v. slow) |
| 27 | |
| 28 | If non-option arguments are present, they are names for tests to run, |
| 29 | unless -x is given, in which case they are names for tests not to run. |
| 30 | If no test names are given, all tests are run. |
| 31 | |
| 32 | -v is incompatible with -g and does not compare test output files. |
| 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 |
| 41 | doing memory analysis on the Python interpreter (which tend to consume |
| 42 | too many resources to run the full regression test non-stop). The |
| 43 | file /tmp/pynexttest is read to find the next test to run. If this |
| 44 | file is missing, the first test_*.py file in testdir or on the command |
| 45 | line 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 |
| 49 | or more test names per line. Whitespace is ignored. Blank lines and |
| 50 | lines beginning with '#' are ignored. This is especially useful for |
| 51 | whittling down failures involving interactions among tests. |
| 52 | |
| 53 | -L causes the leaks(1) command to be run just before exit if it exists. |
| 54 | leaks(1) is available on Mac OS X and presumably on some other |
| 55 | FreeBSD-derived systems. |
| 56 | |
| 57 | -R runs each test several times and examines sys.gettotalrefcount() to |
| 58 | see if the test appears to be leaking references. The argument should |
| 59 | be of the form stab:run:fname where 'stab' is the number of times the |
| 60 | test is run to let gettotalrefcount settle down, 'run' is the number |
| 61 | of times further it is run and 'fname' is the name of the file the |
| 62 | reports are written to. These parameters all have defaults (5, 4 and |
| 63 | "reflog.txt" respectively), so the minimal invocation is '-R ::'. |
| 64 | |
| 65 | -u is used to specify which special resource intensive tests to run, |
| 66 | such as those requiring large file support or network connectivity. |
| 67 | The argument is a comma-separated list of words indicating the |
| 68 | resources to test. Currently only the following are defined: |
| 69 | |
| 70 | all - Enable all special resources. |
| 71 | |
| 72 | audio - Tests that use the audio device. (There are known |
| 73 | cases of broken audio drivers that can crash Python or |
| 74 | even the Linux kernel.) |
| 75 | |
| 76 | curses - Tests that use curses and will modify the terminal's |
| 77 | state and output modes. |
| 78 | |
| 79 | largefile - It is okay to run some test that may create huge |
| 80 | files. These tests can take a long time and may |
| 81 | consume >2GB of disk space temporarily. |
| 82 | |
| 83 | network - It is okay to run tests that use external network |
| 84 | resource, e.g. testing SSL support for sockets. |
| 85 | |
| 86 | bsddb - It is okay to run the bsddb testsuite, which takes |
| 87 | a long time to complete. |
| 88 | |
| 89 | decimal - Test the decimal module against a large suite that |
| 90 | verifies compliance with standards. |
| 91 | |
| 92 | compiler - Test the compiler package by compiling all the source |
| 93 | in the standard library and test suite. This takes |
| 94 | a long time. |
| 95 | |
| 96 | subprocess Run all tests for the subprocess module. |
| 97 | |
| 98 | To enable all resources except one, use '-uall,-<resource>'. For |
| 99 | example, to run all the tests except for the bsddb tests, give the |
| 100 | option '-uall,-bsddb'. |
