QGIS unit tests

Build tests

Make sure that you have enabled building of tests in CMake. cmake -DENABLE_TESTS=ON ..

Run tests

You can run all tests using make check.

Individual tests can be run using ctest.

For example if the output of make check ends like this:

   The following tests FAILED:
         77 - PyQgsLocalServer (Failed)

You could re-run the failing test with:

   ctest -V -R PyQgsLocalServer

The parameter -V enables verbose mode and -R takes a regular expression as parameter and will only run matching tests.

Advanced configuration

Postgres

To test the postgres provider you will need to have a database available to which the postgres provider can connect. This will need to have postgis support enabled and be available as a service called qgis_test on the machine you run the tests on.
