</blockquote>
<p>ctest is just the CMake way of launching the test suite. It will execute C++ tests of autotest/cpp directly, and for tests written in python will launch "pytest autotest/XXXXX" for each directory.
<o:p></o:p></p>
<p>"ctest --test-dir $build_dir -R autotest_ogr -V" will just run all the autotest/ogr tests, which can be quite long already.<o:p></o:p></p>
<p>To test your own development, you may have a more pleasant experience by directly running just the tests for your driver with something like "pytest autotest/ogr/ogr_miramon.py" (be careful on Windows, the content of $build_dir/autotest is copied from $source_dir/autotest
each time "cmake" is run, so if you edit your test .py file directly in the build directory, be super careful of not accidentally losing your work, and make sure to copy its content to the source directory first. That's admittedly an annoying point of the
current test setup on Windows, compared to Unix where we use symbolic links)<o:p></o:p></p>
<p>after setting the environment to have PYTHONPATH point to something like $build_dir/swig/python/Release or $build_dir/swig/python/Debug (I believe you're on Windows?). If you look at the first lines output by the above "ctest --test-dir $build_dir -R autotest_ogr
-V" invokation, you'll actually see the PYTHONPATH value to specify.<o:p></o:p></p>
<p>You also need to first install pytest and other testing dependencies with: python -m pip install autotest/requirements.txt<o:p></o:p></p>
<blockquote style="margin-top:5.0pt;margin-bottom:5.0pt">
<p class="MsoNormal"><span lang="EN-US">There is a minimal test to create?</span><o:p></o:p></p>
</blockquote>
<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Times New Roman",serif;mso-fareast-language:CA">A maximal test suite, you mean ;-) You should aim for a "reasonable" coverage of the code you wrote. Aiming to test the nominal code paths of your
driver is desirable (testing the error cases generally requires a lot more effort).

<p>You don't necessarily need to use other formats. It is actually better if the tests of a format don't depend too much on other formats, to keep things isolated.<o:p></o:p></p>
<p>To test the read part of your driver, add a autotest/ogr/data/miramon directory with *small* test files, ideally at most a few KB each to keep the size of the GDAL repository reasonable, and a few features in each is often enough to unit test, with different
type of geometries, attributes, and use the OGR Python API to open the file and iterate over its layers and features to check their content. Those files should have ideally be produced by the Miramon software and not by the writing side of your driver, to
check the interoperability of your driver with a "reference" software.<o:p></o:p></p>
<p>For the write site of the driver, you can for example run gdal.VectorTranslate(dest, source) on those files, and use again the test function to validate that the read side of your driver likes what the write site has produced. An alternative is also to do
a binary comparison of the file generated by your driver with a reference test file stored in for example autotest/ogr/data/miramon/ref_output. But this may be sometimes a fragile approach if the output of your driver might change in the future (would require
regenerating the reference test files).<o:p></o:p></p>
<p>I'd suggest your test suite also has a test that runs the "test_ogrsf" command line utility which is a kind of compliance test suite which checks a number of expectations for a driver, like that GetFeatureCount() returns the same number as iterating with
GetNextFeature(), etc etc<o:p></o:p></p>
<p>It is difficult to point at a "reference" test suite, as all drivers have their particularities and may need specific tests. Potential sources of inspirations:<o:p></o:p></p>
<p>- autotest/ogr/ogr_gtfs.py . Shows very simple testing of the read side of a driver, and includes a test_ogrsf test<o:p></o:p></p>
<p>- autotest/ogr/ogr_csv.py has examples where the writing side of the driver is checked by opening the output file and checking that some strings are present in it (only easily doable with text based formats)<o:p></o:p></p>
<p>- autotest/ogr/ogr_openfilegdb_write.py . Extensive testing of the writing side of a driver . A lot in it will be specific to the format and irrelevant to your concern, but you should at least find all possible aspects of how to test the write side of a
driver.<o:p></o:p></p>
