[chigia001]

What version of OpenTelemetry are you using?

• @opentelemetry/instrumentation-graphql@0.35.0

What version of Node are you using?

• >=14 <=18

What did you do?

• Run unit test in current repo on github action

What did you expect to see?

• @opentelemetry/instrumentation-graphql's unit test run correctly and return list of test + code coverage report

What did you see instead?

• @opentelemetry/instrumentation-graphql's unit test on github action run success but unable to list out list of test + only report code coverage for symbol.ts file

• pipeline: https://github.com/open-telemetry/opentelemetry-js-contrib/actions/runs/5567559025/jobs/10169539286

• test output:

lerna info run Ran npm script 'test' in '@opentelemetry/instrumentation-graphql' in 49.4s:

> @opentelemetry/instrumentation-graphql@0.35.0 test /home/runner/work/opentelemetry-js-contrib/opentelemetry-js-contrib/plugins/node/opentelemetry-instrumentation-graphql

• code coverage report:

Additional context

• I double check those test on local machine and unable to repproduce this behavior. There are no crash or anything.
• I able to reproduce with codespace, seem like nyc issue when they trying to transform code for codecoverage report. When running ts-mocha without nyc everything seem to work.

@haddasbronfman I think you also face similar problem with mongodb test with #1487 . I will try to switch from ts-mocha to mocha + ts-node like their suggest https://typestrong.org/ts-node/docs/recipes/mocha/ to see if it resolve the issue

[haddasbronfman]

@chigia001 in my case I think also the problem is because of nyc, although in my case I saw an empty table.

@chigia001 is it ok if I assign this to you since you have a PR open?

[chigia001]

@dyladan yes, I think some hoist issue with current setup, will try to come up with smaller PR tmr.
