Testing
=======
This folder contains the testsuite for ``svglib``. In order to run
it before installing the package leave the prefix ``PYTHONPATH=.``
in the commands below. Else the testsuite will test an already
installed ``svglib`` package.
For the simplest test open a terminal, change into this folder and
execute the following command (assuming you have ``pytest`` installed
which is a simple ``pip install pytest``)::
$ PYTHONPATH=. py.test
======================== test session starts =========================
platform darwin -- Python 3…, pytest-3…, py-1…, pluggy-0…
rootdir: /Users/dinu/repos/github/deeplook/svglib, inifile:
plugins: cov-2…
collected 36 items
tests/test_basic.py ............................
tests/test_samples.py .s.s.s.s
=============== 32 passed, 4 skipped in 49.18 seconds ================
If for any reason you don't want to install ``pytest`` you can also
run the following (which installs ``pytest-runner`` during testing)::
$ PYTHONPATH=. python setup.py test
running pytest
running egg_info
writing dependency_links to svglib.egg-info/dependency_links.txt
writing svglib.egg-info/PKG-INFO
writing requirements to svglib.egg-info/requires.txt
writing top-level names to svglib.egg-info/top_level.txt
reading manifest file 'svglib.egg-info/SOURCES.txt'
reading manifest template 'MANIFEST.in'
writing manifest file 'svglib.egg-info/SOURCES.txt'
running build_ext

tests/test_samples.py .s.s.s.s
=============== 29 passed, 4 skipped in 38.95 seconds ================
If you have ``tox`` installed (``pip install tox``) you can simply
run the testsuite on Python 3.8 (assuming you have it installed) or on a
single version (this will not run with ``conda``, yet, though)::
$ tox
$ tox -e py38
All will run the entire testsuite and produce result files in PDF
format in the subdirectories ``tests/samples`` (here also in PNG),
``tests/wikipedia/flags`` and ``tests/wikipedia/symbols``, if the
corresponding SVG input files could be downloaded from the internet
at the start of the test or if they are still available from previous
runs.
To clean-up all files generated by ``svglib`` run this (but keep the
SVG samples downloaded from the web) run this (output not shown)::
$ PYTHONPATH=. py.test -v -s --override-ini=python_functions=cleanup
If you have a ``pytest`` plugin named ``pytest-coverage`` installed
(``pip install pytest-coverage``) you can run this to get a simple
coverage report (after an additional upfront reset which results in
more code being executed and a higher test coverage)::
$ rm tests/samples/W3C_SVG_12_TinyTestSuite.tar.gz
$ rm -rf tests/samples/W3C_SVG_12_TinyTestSuite
$ rm -rf tests/samples/wikipedia/flags
$ rm -rf tests/samples/wikipedia/symbols
$ PYTHONPATH=. py.test --cov=./svglib --cov=tests tests

As an experimental feature some of the tests try using a vector
conversion tool named `UniConvertor
<http://sourceforge.net/projects/uniconvertor>`_
(if installed) for producing PDFs for comparison with `svglib`.
(This was not used for years, though, during development/testing.)
Calling ``renderPM.drawToFile()`` in ``TestW3CSVG.test_convert_pdf_png()``
is known to raise a ``TypeError`` sometimes in reportlab which was
fixed in ``reportlab`` 3.3.26. See
https://github.com/deeplook/svglib/issues/47.
