Tests
-----
* To run all F2PY unit tests in one command::
cd tests
python run_all.py [<options>]
For example::
localhost:~/src_cvs/f2py2e/tests$ python2.2 run_all.py 100 --quiet
**********************************************
Running '/usr/bin/python2.2 f77/return_integer.py 100 --quiet'
run 1000 tests in 1.87 seconds
initial virtual memory size: 3952640 bytes
current virtual memory size: 3952640 bytes
ok
**********************************************
Running '/usr/bin/python2.2 f77/return_logical.py 100 --quiet'
run 1000 tests in 1.47 seconds
initial virtual memory size: 3952640 bytes
current virtual memory size: 3952640 bytes
ok
...
If some tests fail, try to run the failing tests separately (without
the ``--quiet`` option) as described below to get more information
about the failure.
* Test intent(in), intent(out) scalar arguments,
scalars returned by F77 functions
and F90 module functions::
tests/f77/return_integer.py
tests/f77/return_real.py
tests/f77/return_logical.py
tests/f77/return_complex.py
tests/f77/return_character.py
tests/f90/return_integer.py
tests/f90/return_real.py
tests/f90/return_logical.py
tests/f90/return_complex.py
tests/f90/return_character.py
Change to tests/ directory and run::
python f77/return_<type>.py [<options>]
python f90/return_<type>.py [<options>]
where ``<type>`` is integer, real, logical, complex, or character.
Test scripts options are described below.
A test is considered succesful if the last printed line is "ok".
If you get import errors like::
ImportError: No module named f77_ext_return_integer
but ``f77_ext_return_integer.so`` exists in the current directory then
it means that the current directory is not included in to `sys.path`
in your Python installation. As a fix, prepend ``.`` to ``PYTHONPATH``
environment variable and rerun the tests. For example::
PYTHONPATH=. python f77/return_integer.py
* Test mixing Fortran 77, Fortran 90 fixed and free format codes::
tests/mixed/run.py
* Test basic callback hooks::
tests/f77/callback.py
Options
-------
You may want to use the following options when running the test
scripts:
``<integer>``
Run tests ``<integer>`` times. Useful for detecting memory leaks. Under
Linux tests scripts output virtual memory size state of the process
before and after calling the wrapped functions.
``--quiet``
Suppress all messages. On success only "ok" should be displayed.
``--fcompiler=<Gnu|Intel|...>``
Use::
f2py -c --help-fcompiler
to find out what compilers are available (or more precisely, which
ones are recognized by ``numpy_distutils``).
Reporting failures
------------------
XXX: (1) make sure that failures are due to f2py and (2) send full
stdout/stderr messages to me. Also add compiler,python,platform
information.
