Opentelemetry with Mocha - Not getting everything patched

[arimus]

I'm trying to get the opentelemetry stuff working with mocha and I have been able to get each test wrapped correctly in a span by setting everything up in a tracing.js file that is used as a --require to mocha.

However, the code that is being tested doesn't seem to be getting instrumented properly. I have it configured to instrumentation individually and with the auto instrumentation, but none of the mysql2 or knex spans ever get logged, so I assume that they never get patched properly.

It may be worth noting that everything is compiled to commonjs first, then mocha is run all all .spec.js files in the dist output.

Is there anything special that must be done to get mocha to instrument the code being tested as well? Any project examples that anyone can point to that have opentelemetry working with mocha tests?
