Add code coverage: tarpaulin / codecov

[Lan2u]

Relates to issue #378.

Added tarpaulin action to the test suite on Linux section of the CI, the produced report is then submitted to codecov.io. I used my own personal token for testing the codecov part but have removed it for this commit (it can be re-added into the actions file - this is why that stage currently fails).

[Lan2u]

I haven't done much with this except get tarpaulin to run, this is my first attempt to work on an issue as part of an open-source project so if I have missed the mark please let me know.

Thank you for this contribution!
This looks very good, check my comments, though.

It seems that you removed the Cargo.lock file. This is not a big deal, it can be regenerated by running cargo update.

We also don't need two workflows, so we don't need .github/workflows/coverage.yml files.

If this is your first contribution to open source, congrats! keep them coming! :)

We don't need to specify a token, since this is a public repository. This can be removed :)

[Lan2u]

I removed this but it seems to still fail? Perhaps it is because I'm trying from my fork of the repo.

[Razican]

I think this is because we still don't have the project in CodeCov. Public repos shouldn't need a token.

It seems you modified the Cargo.lock file. Could we avoid this? It's giving merge conflicts, but there should be no modification to that file :)

Done, sorry I thought I already removed it.

Ok, let's wait for @jasonwilliams to see if we can have Boa in codecov so that this works :)

[jasonwilliams]

I've now added the repo, give it a try and let us know

Tried again but still codecov fails saying it needs a token

[jasonwilliams]

@Lan2u could you try again?

[Lan2u]

@Lan2u could you try again?

Tried again, the same result unfortunately :(

[Razican]

I think it just needs to be initialized. We could try to merge this without the token and see if it works.

Lets see what happens

Perhaps related to https://community.codecov.io/t/github-public-repository-issues/1360?

Will try and investigate further

Seems to be fixed, Pull request #436
