This is one of the rare cases in which the official documentation of an API is severely lacking synchronization with the actual provided API.
So, the jcabi-manifests API documentation clearly states here that manifest entries can be statically mocked using the utility class Manifests. Unfortunately, the static methods described in the mentioned page - e.g. inject(), snapshot(), revert() - are missing from the actual API.
Has anybody been able to use the manifest mocking feature supposedly being delivered with jcabi-manifests? If yes, how?
