Expected Behavior

Observed Behavior

.travis.yml runs after_success: nyc npm test && nyc report --reporter=text-lcov | coveralls which consistently fails as shown above.

I think have inconsistently seen a similar issue in my local environment, but haven’t been able to reproduce it consistently.

Could you try setting the ESM_DISABLE_CACHE environmental variable noted in https://github.com/standard-things/esm? Maybe try cross-env ESM_DISABLE_CACHE=1 nyc --cache=false npm test? Just to try ruling out issues caused by caching.

I think this problem is unchanged.

It is less urgent for me as I found the workaround (above) of running nyc npm test twice.

I still have similar problems in my local development environment, and sometimes don’t seem to be able to generate coverage at all.
