Description

As a follow-up of keycloak/keycloak#31869, we need to add more tests for the admin-client from this package of keycloak repository to this package of keycloak-client repository.

With #36, AdminClientTest, RealmTest, RealmRolesTest, and ClientTest were already added.

The idea is to add the most important test classes to cover the most important use-cases and the CRUD operations of the basic admin objects.

What tests to add

maybe UsersTest and UserTest

also some tests from authentication package: https://github.com/keycloak/keycloak/tree/main/testsuite/integration-arquillian/tests/base/src/test/java/org/keycloak/testsuite/admin/authentication

the client package for client scopes, sessions, client roles: https://github.com/keycloak/keycloak/tree/main/testsuite/integration-arquillian/tests/base/src/test/java/org/keycloak/testsuite/admin/client (edited)

maybe the GroupTest
