Expected Behavior

Observed Behavior

image

.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.

Forensic Information

Ubuntu 14.04.5 LTS, Mac OS X 10.13.3, Windows Node 8.15.0, 10.15.1, 11.10.0, nyc 13.3.0

Research direction
Investigate the .travis.yml file in the linked repository (https://github.com/chrisveness/geodesy) to see how nyc is invoked. Check nyc version and configuration. Look at the TravisCI build log (https://travis ci.org/chrisveness/geodesy/jobs/493767331#L2781) for errors. Consider if the issue is related to the shell command 'nyc npm test && nyc report reporter=text lcov | coveralls' and whether nyc outputs to stdout correctly. Examine nyc's behavior with test frameworks and coveralls integration.
