Fixes #514
Make sure you have Pull request status updates and webhooks turned on in the codeclimate settings page for the repo
Thanks!

@jywarren I didn't integrate test coverage with travis since coveralls already does this.(supposed to do this. Until #491 is fixed)

[jywarren]

Couple things here, i noticed CodeClimate had the default branch set to master so I changed it to main.

I also turned on PR status updates but the webhooks isn't turning on -- i press "Install" but it still shows the "Install" button, unlike the PR status updates.

[jywarren]

Hmm, i can't seem to get it to turn on. Should I merge this anyways?

[kaustubh-nair]

Ah the webhooks button has a bug. It shows "install" after webhooks gets installed successfully. So I think that's fine!

[jywarren]

Ok then!!!

[jywarren]

Great work here!!!

@jywarren Most of the issues on codeclimate are rubocop style offences(2000/2300)
I can break these up in small parts and create a lot of FTO issues. Should I proceed with this?

[grvsachdeva]

hey @kaustubh-nair, if you can open FTOs for those codeclimate issues that'd be great. Thank you!

[kaustubh-nair]

@gauravano Most of them are refactoring issues due to too many lines of code. I think that will be too much for a first timer? Or will it not?

[grvsachdeva]

Hmm, it depends on how good codeclimate describes the solution. Sometimes, their solution is good and sometimes not. But, I have also dropped a word in #533 so maybe we can use those for generating FTOs and yeah, we have to do the effort.
