### test_import_api_packages

This Python test verifies whether the API v2 packages can be imported from the
current build. It utilizes the `_api/v2/api_packages.txt` list of packages from
the local wheel file specified in the `requirements_lock_<python_version>.txt`.

Packages are imported one by one in alphabetical order during runtime.

            v1 = existingSource,
            v2 = internalSource
        ).assertEmptyReport()
    }

    @Test
    fun `existing internal members made public appear as added`() {
