still active:

• |version|

• |docs|
• |wheel|

removed in #59:

• |travis| (see 9088860)
• |appveyor| (see 9088860)
• |requires| The link had lead to the login page of require.io. Other people had the same issue: https://github.com/OpenDataServices/cove/issues/1344
• |coveralls| Last built had been on 2020-06-09. (possibly broken in 9088860)
• |codecov| Most recent commit had been a year ago. (also possibly broken in 9088860)
• |scrutinizer| last inspection 3 years ago; apparently costs something
• |codacy| not working ("Request handler not found: /project/gnn/oemof-tabular/dashboard")
• |codeclimate| only one build which was 3 years ago

to be re-introduced: [ ] coveralls: test coverage [ ] codacy: security issues, code coverage, code duplication, code complexity [ ] requires: monitors dependencies (please feel free to edit this list if you disagree)

@henhuy Some of the badges are not working or not used anymore but I couldn't find where they have been removed. I think some can just be dropped. Could you find out for those that are worth keeping why they have stopped working?

[henhuy]

I can have a look. As we switched from travis to Github Actions some tests and code coverage are not shipped (yet). Thus, badges cannot work. Some badges I would remove, as I'm not familiar with them. Will check

@monika-o: Can you please update the list above? We can keep this issue open so that it gives an overview over what happened and which badges could be re-introduced later.
