[/unit_test_1] This command test cycles through all possible charts in the currently loaded chart database, adjusting the viewport to show the loaded chart automatically. The value of this test is clear: it provide an unattended stress test of OpenCPN, It is most fun to watch in quilt mode….. The test runs until all charts in the database have been visited once. A side-effect of this switch is that it can be used to process a set of ENC charts into SENC files. The first, time consuming processing of ENC charts, can this way be done unattended.
