@ -6,34 +6,51 @@ 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.
|
||||
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

- Issue #6293: Have regrtest.py echo back sys.flags. This is done by default
|

in whole runs and enabled selectively using ``--header`` when running an

explicit list of tests. Original patch by Collin Winter.
