don't ignore `min_coverage` in `mix coveralls.json`

[duksis]

First of all - thanks for your work!

currently min_coverage option seems to only be taken into account when using mix coveralls and mix coveralls.html tasks.

https://github.com/parroty/excoveralls/blame/b706b5da6d3a62ff51552059cf57726c6ad104e5/README.md#L426...L427

I would like to use the min_coverage option and generate a json file.

if I understand that right I would need to run my test suite twice in order to achieve both - the failure on below min_coverage and a json file.

I would prefer not to do that.

1. Is there another way to achieve both?
2. would it make sense to check min_coverage in mix coveralls.json?

Thanks

Thank you for the feedback 🙇 . I assume it's related to https://github.com/parroty/excoveralls/pull/286.

While it may make sense to have that feature for mix coveralls.json, my concern is that it can become a breaking change. If it can be taken as optional feature, it might be good to add that capability, though.

@parroty couldn't find any reports here but the same thing happens with coveralls.github the min coverage is just ignored.

+1 for not ignoring minimum_coverage when running mix coveralls.github too

I'm currently seeing this situation on GitHub Actions:

coverage/coveralls Expected — Waiting for status to be reported

Even though coverage is visible on their website:

Successfully uploaded the report to 'https://coveralls.io/'

To work around that (for now), I could disable the branch requirement for coverage/coveralls. But it would be nice if the coveralls.json minimum_coverage setting would act as a fallback in that situation, so we still fail CI if coverage falls too much.

Thank you for the comment 🙇 . I am now checking this item through #305.
