Bash one-liner for Apex test coverage percentage using SalesforceDX

Update 3 May 2018: There are issues with the percentages reported by SalesforceDX plus it doesn’t report coverage on classes with 0% coverage which will shrew the results. The approach outlined above can be used as an indication but cannot as of today be used as a measure for code coverage when it comes to production deployments. As an example I’ve had the above snippet report a coverage of 88% where as a production deploy reported 63% coverage. We – Salesforce – are aware of the issue and are working to resolve it. Stay tuned!

Note to self – quick note on how to run all tests in a connected org (as identified by the -u argument) and use jq and awk to grab the overall test coverage percentage.

$ sfdx force:apex:test:run -u mheisterberg@example.com.appdev -c -w 2 -r json | jq -r ".result.coverage.coverage[].coveredPercent" | awk '{s+=$1;c++} END {print s/c}'
> 88.1108

YMMV!
