bug: file missing from coverage #232
Description
- Version: 7.2.0
- Platform: Linux, Node.js v14.5.0
I’m seeing this error:
file: /root/brrp/src/rollup-iter.js error: TypeError: Cannot read property 'sources' of null
at V8ToIstanbul.load (/root/brrp/node_modules/v8-to-istanbul/lib/v8-to-istanbul.js:46:34)
at Report.getCoverageMapFromAllCoverageFiles (/root/brrp/node_modules/c8/lib/report.js:88:25)
at async Report.run (/root/brrp/node_modules/c8/lib/report.js:59:20)
at async exports.outputReport (/root/brrp/node_modules/c8/lib/commands/report.js:27:3)
at async /root/brrp/node_modules/c8/bin/c8.js:39:9
As a result the file src/rollup-iter.js is missing from coverage and c8 passes the full coverage check :(

Sorry for this being a little terse, I plan to return to this and debug a little bit more. It looks like it’s in v8-to-istanbul so I can at least track it down more, maybe even send a fix, but I wanted to get this logged before I forgot about it and moved on :)
