Detect missing readme headers

[ernilambar]

Related to https://github.com/WordPress/plugin-check/issues/402

• Added check_headers() method in Plugin_Readme_Check
• Add separate private method for getting ignored filters get_ignored_warnings()
• Two headers are checked here:
  • Tested up to
  • Contributors
• New method will check if those fields are empty
• Checking for the field is enabled/disabled based on wp_plugin_check_ignored_readme_warnings
• Since contributor_ignored is returned from the above filter, detecting of Contributors is disabled.

If the PR is acceptable then I will add tests for the changes and update other tests accordingly. Other tests also need to be updated because currently we have assumed there will be no warning for missing Tested up to field.

Hi @ernilambar thanks for the change. It looks good, if you finish the tests I can continue with the review.

PR has been rebased with trunk and few more updates have been done.

For me It's ok after all changes! In the future, we would need to get the actual version of WordPress somewhere and create a warning if it's not getting an actual version.

I would add to check the actual version of WordPress. It must be Tested up "actual version".

In order to have always the latest version, I've asked to meta, and we have some methods to check that:

Yes, use one of these:
https://api.wordpress.org/core/stable-check/1.0/
3rd line of https://api.wordpress.org/core/version-check/1.1/
Or just json decode https://api.wordpress.org/core/version-check/1.7/

So finally we have a complete check.

The error that we show to the users is something like this ERROR: Tested up to: 6.4 < 6.5

@davidperezgar Should this be done in this same PR or separate PR?

[davidperezgar]

In a separate Issue. I'll create the issue #481
