Create-react-app: Support Jest collectCoverageFrom option

Created on 11 Oct 2016  路  7Comments  路  Source: facebook/create-react-app

When Jest performs code coverage, it seems to only cover the files that were tested instead of all files in my source directory. This gives a skewed percentage of files tested.

Jest 15 added a new config option for this called `collectCoverageFrom``

Can we have support for this in CRA?

We can add it to our config. Should it just look at app's src/? Would you like to send a PR?

Any update on this ? Is the PR acceptable ? I notice its not CLA signed so does it need to be resubmitted ?
