JUnit5's @RegisterException is not supported.

[SomeDeveloper13]

The KeycloakMock is not supported as an Extention, so this does not work despite the instructions:

	@RegisterExtension
	protected static KeycloakMock mock = new KeycloakMock();

You get the following error:

org.junit.platform.commons.PreconditionViolationException: Failed to register extension via @RegisterExtension field [protected static com.tngtech.keycloakmock.api.KeycloakMock some.path.IntegrationTest.mock]: field value's type [com.tngtech.keycloakmock.api.KeycloakMock] must implement an [org.junit.jupiter.api.extension.Extension] API.

You are using the wrong class. You need to use com.tngtech.keycloakmock.junit.KeycloakMock, but you are using com.tngtech.keycloakmock.api.KeycloakMock. I admit the naming is confusing though.

[SomeDeveloper13]

Is there a separate dependency for that?
I don't see a com.tngtech.keycloakmock.junit.KeycloakMock in the jar.

[SomeDeveloper13]

Looks like I missed an instruction:
Readme states to use mock-junit for both JUnit4 & JUnit5.

I saw a config for a mock-junit5, can I use just that if we exclude JUnit4 jars in our project only allowing JUnit5?

[ostrya]

The mock-junit5 module comes from the initial draft of the library. In the mean time, we've decided to combine the mock-junit and mock-junit5 support. While you can at the moment use the mock-junit5 dependency, we plan to discontinue it in the next major release.

Is including a transient dependency on junit4 really a blocker for you?

[SomeDeveloper13]

Testing it, but will close this for the time being.
Thanks for the info!.
