"""
|
||||
Automatic Python regression test.
|
||||
|
||||
The list of individual tests is contained in the `testall' module.
|
||||
These test some (but not all) essential parts of the Python
|
||||
interpreter and built-in modules. When a test fails, an exception is
|
||||
raised and testing halts. When a test succeeds, it can produce quite
|
||||
a lot of output, which is compared against the output from a previous
|
||||
run. If a difference is noticed it raises an exception; if all is
|
||||
well, it prints nothing except 'All tests OK.' at the very end.
|
||||
|
||||
The output from a previous run is supposed to be contained in separate
|
||||
files (one per test) in the `output' subdirectory somewhere on the
|
||||
search path for modules (sys.path, initialized from $PYTHONPATH plus
|
||||
some default places).
|
||||
|
||||
Of course, if the normal output of the tests is changed because the
|
||||
tests have been changed (rather than a test producing the wrong
|
||||
output), 'autotest' will fail as well. In this case, run 'autotest'
|
||||
with the -g option.
|
||||
|
||||
Usage:
|
||||
|
||||
%s [-g] [-w] [-h] [test1 [test2 ...]]
|
||||
|
||||
Options:
|
||||
|
||||
-g, --generate : generate the output files instead of verifying
|
||||
the results
|
||||
|
||||
-w, --warn : warn about un-importable tests
|
||||
|
||||
-h, --help : print this message
|
||||
|
||||
If individual tests are provided on the command line, only those tests
|
||||
will be performed or generated. Otherwise, all tests (as contained in
|
||||
testall.py) will be performed.
