Missing SimpleCov JSON specification (with comparison to Cobertura XML format)

[abitrolly]

SimpleCov can generate coverage report in JSON format by default without additional dependencies. JSON is easier to parse than XML, but even Ruby shops like GitLab support only Cobertura XML for digesting coverage info.

I am interested to know what other advantages or SimpleCov JSON over Covertura XML format?
Is there some additional info that could be useful?
Anything Ruby specific that helps somehow?

Is there some reason you’re not able to use the simplecov-cobertura gem for this? Cc: @jessebs

@sferik that was long ago. I don't remember what I was doing. Probably some online/automation helper.

The main problem with Cobertura XML is that it is undocumented, so tools support it differently https://gitlab.com/gitlab-org/gitlab/-/work_items/552634

The same problem is with SimpleCov JSON.

@abitrolly Can I close this issue?

[abitrolly]

@sferik I renamed the issue to more closely reflect the problem - absent specification and versioning of SimpleCov makes it hard to write compatible tools to support it. The absence of comparison with Cobertura XML makes it hard to decide where to use which.

SimpleCov JSON Pros

• doesn't require external dependencies and XML libs

I have an open pull request that would add a JSON Schema to this project. Would merging that resolve this issue for you?
