"""
Tests for auth manager PKI access to postgres.
This is an integration test for QGIS Desktop Auth Manager postgres provider that
checks if QGIS can use a stored auth manager auth configuration to access
a PKI protected postgres.
Configuration from the environment:
* QGIS_POSTGRES_SERVER_PORT (default: 55432)
* QGIS_POSTGRES_EXECUTABLE_PATH (default: /usr/lib/postgresql/9.4/bin)
From build dir, run: ctest -R PyQgsAuthManagerPKIPostgresTest -V
or, if your postgresql path differs from the default:
QGIS_POSTGRES_EXECUTABLE_PATH=/usr/lib/postgresql/<your_version_goes_here>/bin \
ctest -R PyQgsAuthManagerPKIPostgresTest -V
