Yes Dave, this morning itself I experimented this lcov report generation with sonarqube.

Imported it in sonarqube server (local) & it worked very well. In fact it started showing coverage progress for all the JS files in dir.

Also its possible to include multiple lcov files (language specific i.e python/js) for coverage report generation.

Hmm, this makes me think - if we have enough of the JS infrastructure on the SonarQube scanner server (which is easy to create in the Jenkins job), we could import the lcov reports into SonarQube.

Hi Pramod,

The patch looks good to me except:

1) Remove commented code.

2) Make coverage report optional using command line flag --reporters. Add a new cmd in yarn - test:karma-coverage.

3) Add the new coverage directory to .gitignore.

Hi Team,

As recent updates have added ability to generate code coverage report for all the JS files.

Where had added two new packages as below:


istanbul-instrumenter-loader
karma-coverage

Steps to generate report:

Apply attached patch
Do - ‘npm install’
Run – ‘yarn run test:karma’
It has below type of output formats supported:

Html
Lcov
Cobertura
Lcovonly
Teamcity
Text
Text-summery

All the output files will be generated & stored in ‘root_dir/coverage’ folder .

Please do let me know your thoughts or suggestion if any.
