How to Test AzerothCore PRs

When a PR is ready to be tested, it will be marked as [WAITING TO BE TESTED].

You can help by testing PRs and writing your feedback here on the PR's page on GitHub. Follow the instructions here:

http://www.azerothcore.org/wiki/How-to-test-a-PR

REMEMBER: when testing a PR that changes something generic (i.e. a part of code that handles more than one specific thing), the tester should not only check that the PR does its job (e.g. fixing spell XXX) but especially check that the PR does not cause any regression (i.e. introducing new bugs).

For example: if a PR fixes spell X by changing a part of code that handles spells X, Y, and Z, we should not only test X, but we should test Y and Z as well.

CI is failing because of breaking changes related to the modules

[sudlud]

Can you please prepare PR(s) for the affected modules from the failed module ci. Thanks

[sudlud]

Please see my last comment.

[Exitare]

Who is the maintainer of the module? This will essentially break every module out there.

[sudlud]

The immediate relevant modules are those that fail in the modules build of this pr.
Other modules can be updated later on.

Any staff member (with sufficient rights) can approve and merge PRs on modules under the azerothcore organization on GitHub.
