RDM Responder Testing

OLA comes with a suite of tests for RDM responders which can be used to check how well an RDM device implements the E1.20 specification. Writing RDM Responder Tests explains how to add to / improve the tests.

Setup the Test Rig

The following controller devices are supported:

• RDM-TRI
• DMXter4 RDM / MiniDMXter

Connect the device under test to the controller device and start olad. Patch the output port on the controller device to a universe (UNIVERSE_NUMBER). Then run ola_rdm_discover, you should see the responder's UID appear:

 $ ola_rdm_discover -u UNIVERSE_NUMBER
 00a1:00010003
 7a70:ffffff00

Running the Tests

The tests are written in Python, and run using ola_rdm_test.py. Below is the output from a typical test run:

 ./ola_rdm_test.py --universe 1  --pid_file ../../python/pids.config  00a1:00010003
 Starting tests, universe 3, UID 00a1:00010003
 SetManufacturerLabel: Passed
 SetSoftwareVersionLabel: Passed
 GetManufacturerLabel: Passed
 GetSoftwareVersionLabelWithData: Failed

Useful Options

ola_rdm_test.py has some options which can assist in debugging failures. For a full list of options run with -h

-d, --debug

Show all debugging output, including actual & expected responses.

-t Test1,Test2 , --tests=Test1,Test2

Only run a subset of the Tests. Only the tests listed (and their dependancies) will be run.
