The Compare close contains a close method that checks to see if there
is any unconsumed data in the Compare instance; i.e. if the canonical
output file contains more data than was produced by the current test
run. This method was never called, allowing differences to go
undetected.
Fix is to call close after the test is run (after __import__)
output/test_long and output/test_popen2 needed trivial changes
output/test_select contained lots of text, but test_select.py produced
no output

"""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
|
|
|
|
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 Purifying
|
|
the Python interpreter. 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).

Users other than the Python test suite will certainly want to

Python test suite is searched for.

If the tests argument is omitted, the tests listed on the

files beginning with test_ will be used.
