Try to read about "boundary scan" on internet, it's a good start to understand digital board testing.

Then you can develop a selftest code that can do some basic things. Exemple you start a Bluetooth advertising and on a production device you check that you seeing it with a power level that looks normal. You do a led blinking and an operator check if it's OK (minimise or group operator interventions because it's the expensive part of the test).

If you want a good balance tested vs cost avoid to test again a thing that was implicitly already tested and useless test (testing something so rare that it's less expensive to manage it than testing it every time)

For mass programming your nRF5x boards, have a look at this IDAP-Link. You can use it to parallel program multiple boards at the same time. Supports both nRF51 & nRF52 series.
