somewhere inside a line, use ndiff so that intraline difference marking can point out what changed within a line. I don't remember diff-style abbreviations either (haven't used it since '94, except to produce patches), so say the rest in English too.

"""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
|
|
-q: quiet -- don't print anything except if a test fails
|
|
-g: generate -- write the output file for a test instead of comparing it
|
|
-x: exclude -- arguments are tests to *exclude*
|
|
-s: single -- run only a single test (see below)
|
|
-r: random -- randomize test execution order
|
|
-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
|
|
|
|
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.
|
|
|
|
-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 to 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).
|
|
|
|
-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:
|
|
|
|
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.
