[Xen-devel] [PATCH] tools/python: Drop test.py



This file hasn't been touched since it was introduced in 2005 (c/s 0c6f36628)
and has a wildly obsolete shebang for Python 2.3.  Most importantly for us is
that it isn't Python 3 compatible.

Drop the file entirely.  Since the 2.3 days, automatic discovery of tests has
been included in standard functionality.  Rewrite the test rule to use
"$(PYTHON) -m unittest discover" which is equivelent.

Dropping test.py drops the only piece of ZPL-2.0 code in the tree.  Drop the
ancillary files, and adjust COPYING to match.

This wants backporting to 4.13 as soon as practical.

-test.py [-abBcdDfFgGhklLmMPprstTuUv] [modfilter [testfilter]]
-
-Find and run tests written using the unittest module.
-
-The test runner searches for Python modules that contain test suites.
-It collects those suites, and runs the tests.  There are many options
-for controlling how the tests are run.  There are options for using
-the debugger, reporting code coverage, and checking for refcount problems.
-
-The test runner uses the following rules for finding tests to run.  It
-searches for packages and modules that contain "tests" as a component
-of the name, e.g. "frob.tests.nitz" matches this rule because tests is
-a sub-package of frob.  Within each "tests" package, it looks for
-modules that begin with the name "test."  For each test module, it
-imports the module and calls the module's test_suite() function, which must
-return a unittest TestSuite object.
-
-Options can be specified as command line arguments (see below). However,
-options may also be specified in a file named 'test.config', a Python
-script which, if found, will be executed before the command line
-arguments are processed.
-
-The test.config script should specify options by setting zero or more of the
-global variables: LEVEL, BUILD, and other capitalized variable names found in
-the test runner script (see the list of global variables in process_args().).
-
-
--a level
---at-level level
---all
-    Run the tests at the given level.  Any test at a level at or below
-    this is run, any test at a level above this is not run.  Level 0
-    runs all tests.  The default is to run tests at level 1.  --all is
-    a shortcut for -a 0.
-
--b
---build
-    Run "python setup.py build" before running tests, where "python"
-    is the version of python used to run test.py.  Highly recommended.
-    Tests will be run from the build directory.
-
--B
---build-inplace
-    Run "python setup.py build_ext -i" before running tests.  Tests will be
-    run from the source directory.
-
--c
---pychecker
-    use pychecker
-
--d
---debug
-    Instead of the normal test harness, run a debug version which
-    doesn't catch any exceptions.  This is occasionally handy when the
-    unittest code catching the exception doesn't work right.
-    Unfortunately, the debug harness doesn't print the name of the
-    test, so Use With Care.
-
--D
---debug-inplace
-    Works like -d, except that it loads pdb when an exception occurs.
-
---dir directory
--s directory
-    Option to limit where tests are searched for. This is important
-    when you *really* want to limit the code that gets run.  This can
-    be specified more than once to run tests in two different parts of
-    the source tree.
-    For example, if refactoring interfaces, you don't want to see the way
-    you have broken setups for tests in other packages. You *just* want to
-    run the interface tests.
-
--f
---skip-unit
-    Run functional tests but not unit tests.
-    Note that functional tests will be skipped if the module
-    zope.app.tests.functional cannot be imported.
-    Functional tests also expect to find the file ftesting.zcml,
-    which is used to configure the functional-test run.
-
--F
-    DEPRECATED. Run both unit and functional tests.
-    This option is deprecated, because this is the new default mode.
-    Note that functional tests will be skipped if the module
-    zope.app.tests.functional cannot be imported.
-
--g threshold
---gc-threshold threshold
-    Set the garbage collector generation0 threshold.  This can be used
-    to stress memory and gc correctness.  Some crashes are only
-    reproducible when the threshold is set to 1 (agressive garbage
-    collection).  Do "-g 0" to disable garbage collection altogether.
-
--G gc_option
---gc-option gc_option
-    Set the garbage collection debugging flags.  The argument must be one
-    of the DEBUG_ flags defined bythe Python gc module.  Multiple options
-    can be specified by using "-G OPTION1 -G OPTION2."
-
--k
---keepbytecode
-    Do not delete all stale bytecode before running tests
-
--l test_root
---libdir test_root
-    Search for tests starting in the specified start directory
-    (useful for testing components being developed outside the main
-    "src" or "build" trees).
-
--L
---loop
-    Keep running the selected tests in a loop.  You may experience
-    memory leakage.
-
--m
--M  minimal GUI. See -U.
-
--P
---profile
-    Run the tests under hotshot and display the top 50 stats, sorted by
-    cumulative time and number of calls.
-
--p
---progress
-    Show running progress.  It can be combined with -v or -vv.
-
--r
---refcount
-    Look for refcount problems.
-    This requires that Python was built --with-pydebug.
-
--t
---top-fifty
-    Time the individual tests and print a list of the top 50, sorted from
-    longest to shortest.
-
---times n
---times outfile
-    With an integer argument, time the tests and print a list of the top <n>
-    tests, sorted from longest to shortest.
-    With a non-integer argument, specifies a file to which timing information
-    is to be printed.
-
--T
---trace
-    Use the trace module from Python for code coverage.  The current
-    utility writes coverage files to a directory named `coverage' that
-    is parallel to `build'.  It also prints a summary to stdout.
-
--u
---skip-functional
-    CHANGED. Run unit tests but not functional tests.
-    Note that the meaning of -u is changed from its former meaning,
-    which is now specified by -U or --gui.
-
--U
---gui
-    Use the PyUnit GUI instead of output to the command line.  The GUI
-    imports tests on its own, taking care to reload all dependencies
-    on each run.  The debug (-d), verbose (-v), progress (-p), and
-    Loop (-L) options will be ignored.  The testfilter filter is also
-    not applied.
-
--m
--M
---minimal-gui
-    Note: -m is DEPRECATED in favour of -M or --minimal-gui.
-    -m starts the gui minimized.  Double-clicking the progress bar
-    will start the import and run all tests.
-
-
--v
---verbose
-    Verbose output.  With one -v, unittest prints a dot (".") for each
-    test run.  With -vv, unittest prints the name of each test (for
-    some definition of "name" ...).  With no -v, unittest is silent
-    until the end of the run, except when errors occur.
-
-    When -p is also specified, the meaning of -v is slightly
-    different.  With -p and no -v only the percent indicator is
-    displayed.  With -p and -v the test name of the current test is
-    shown to the right of the percent indicator.  With -p and -vv the
-    test name is not truncated to fit into 80 columns and it is not
-    cleared after the test finishes.
-
-
-modfilter
-testfilter
-    Case-sensitive regexps to limit which tests are run, used in search
-    (not match) mode.
-    In an extension of Python regexp notation, a leading "!" is stripped
-    and causes the sense of the remaining regexp to be negated (so "!bc"
-    matches any string that does not match "bc", and vice versa).
-    By default these act like ".", i.e. nothing is excluded.
-
-    modfilter is applied to a test file's path, starting at "build" and
-    including (OS-dependent) path separators.
-
-    testfilter is applied to the (method) name of the unittest methods
-    contained in the test files whose paths modfilter matched.
-
-Extreme (yet useful) examples:
-
-    test.py -vvb . "^testWriteClient$"
-
-    Builds the project silently, then runs unittest in verbose mode on all
-    tests whose names are precisely "testWriteClient".  Useful when
-    debugging a specific test.
-
-    test.py -vvb . "!^testWriteClient$"
-
-    As before, but runs all tests whose names aren't precisely
-    "testWriteClient".  Useful to avoid a specific failing test you don't
-    want to deal with just yet.
-
-    test.py -M . "!^testWriteClient$"
-
-    As before, but now opens up a minimized PyUnit GUI window (only showing
-    the progress bar).  Useful for refactoring runs where you continually want
-    to make sure all tests still pass.
