This category contains articles related to subjects that only existed in the alpha, beta, or PTR versions of World of Warcraft or its expansions for testing purposes. They should probably not be indexed in other categories.

To place an article into this category, use {{Testing}} at the top of the page, and it will result in an informative banner stating that the subject did not and was not intended to appear in the live game.

For content that was intended to go live but was scrapped during an alpha, beta, or PTR stage, see Category:Removed from alpha, Category:Removed from beta, and Category:Removed from testing realms.
