nyc does not check coverage from given file

[aalexgabi]

Expected Behavior

nyc check-coverage --statements 90 test/coverage/coverage-final.json

Should check coverage compared to test/coverage/coverage-final.json

Observed Behavior

It checks coverage compared to .nyc_output folder

Because I use async class methods I can't use istanbul but when I need to check coverage I have to use istanbul check-coverage due to limitations of nyc check-coverage:

istanbul check-coverage --statements 90 test/coverage/coverage-final.json

Forensic Information

Operating System: Manjaro

node v8.9.2
npm 5.5.1

Hi @aalexgabi sorry for the late reply - I think if you specify --temp-dir test/coverage/ with the appropriate .json files in that folder this should work! Let me know if not.

That is correct, --temp-dir test/coverage will work. An issue that remains is nyc check-coverage --help does not list this as a valid flag, so I think this is a documentation issue.

EDIT: Never mind! This actually is not documented atm by npx nyc check-coverage --help.

@coreyfarrell I think we can just close this issue since the question has been answered and the --temp-dir option is documented by npx nyc check-coverage --help. There's also a FAQ link on the https://istanbul.js.org website that links to all question-issues whether they're open or closed :)`
