I was able to mock the $ga of Vue analytics but the method using it, was not returning anything, so I had to return something, hence I returned the return of the $ga.event function

Please review and check if I have left any cases like last time

[akmadian]

@hemanth-hk We don't need to mock ga as there's no way I know of to verify that the event was received by ga without writing a bunch more code. Please remove all ga stuff and I'll have another look :)

[hemanth-hk]

When I removed the ga stuff the test coverage was not 100%

This is the screenshot of the unit test before mocking $ga

When I removed the ga stuff the test coverage was not 100%

It's ok for coverage not to be 100% in this case.

Thank you for your contribution, @hemanth-hk !
I removed GA mocking, and will merge this PR.

[hemanth-hk]

@obulat I would have removed them if you have just left a comment but please make sure you also remove the return statement form the Helpsection.vue component which I added to check it

[obulat]

Sorry about that, @hemanth-hk . I wanted to add some changes to quickly clean up errors in the repo to make it easier for other contributors to work on it, that is why I added some more changes here. Unfortunately, I didn't notice the return statement. Could you please create a PR removing it?

[hemanth-hk]

I added them in #154, That would be fine right?

[obulat]

Sure, you acted before I could reply. Thank you again, the repo is linted and test run well now!
