Missing file in coverage report (Jest)

[maxpou]

Hi,

I'm getting coverage issues with Jest.
When I set mapCoverage: true, some files disapear from the coverage report.

Example:

# mapCoverage:true
src/api                |      100 |      100 |      100 |      100 |                |

(I remove some file for a better readability. See full coverage report (link to travis build):

All sources files are available here: https://github.com/maxpou/gitvub and jest config here

Thank you

that would probably an issue to report at https://github.com/eddyerburgh/vue-jest - since it only seems to affect .vue files. Otherwise, this is a jest-specific qustion and not related to the template itself.

/ping @eddyerburgh

Edit: With mapCoverage:false, the user.js file isn't in the list, with true it is - so just the other way around...

I'll look into this issue, I'm unsure whether it's a problem with vue-jest or jest. @maxpou I'm copying your issue to the vue-jest repo

@eddyerburgh Please link the new issue here and close this one ok? thanks
