Nyall Dawson 5b244ae88c [FEATURE] More geometry functions for expressions
- add accessors: geometry_n, interior_ring_n
- add num_geometries, num_rings, num_interior_rings
- add nodes_to_points for converting every node in a geometry
to a multipoint geometry
- add segments_to_lines for converting every segment in a geometry
to a multiline geometry

nodes_to_points and segments_to_lines are intended for use with
geometry generator symbology, eg to allow use of m and z values
for nodes/lines with data defined symbology.

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

Make sure that you have enabled building of postgres test in CMake. cmake -DENABLE_PGTEST=ON ..

To test the postgres provider you will need to have a database available to which the postgres provider can connect. The server will need to have postgis support enabled. By default the test uses the following connection options: dbname='qgis_test' host=localhost port=5432 user='postgres' password='postgres'

If this does not match your setup you can set the environment variable QGIS_PGTEST_DB to the desired connection string.

Please note that the database needs to be initialized using the sql-script tests/testdata/provider/testdata.sql It takes care of activating postgis for the test database and creates some tables containing test data.
