| """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 |
| -d: debug -- print traceback for failed tests |
| -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 |
| -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 |
| -n: nowindows -- suppress error message boxes on Windows |
| |
| 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. |
| |
| -v is incompatible with -g and does not compare test output files. |
| |
| -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. |
| |
| lib2to3 - Run the tests for 2to3 (They take a while.) |
| |
| 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. |
| |
| compiler - Allow 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. |
| |
| 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'. |
