Check the Test Rig is in Working Order

Note

Assuming you’ve followed the quickstart guide or otherwise got an IPython terminal to control a test rig…

There are a series of plans for exercising the test rig, which assert that the hardware and Ophyd devices are behaving as expected.

Note

The test rig hardware is not production quality and may occasionally behave inconsistently. If the exercises fail, it may be worth trying them again a couple of times.
