Add test related to creating group with sample attributes - #40558

js/libs/keycloak-admin-client/test/groups.spec.ts:50

• The assertion only verifies the existing create API behavior and does not prove that attributes were serialized and persisted. Fetch the created group and assert both attribute arrays so a regression that silently drops attributes fails this test.

    expect(group.id).to.be.ok;

js/libs/keycloak-admin-client/test/groups.spec.ts:49

• This new top-level group is never removed: the suite teardown only deletes currentGroup, so basic-group remains in the shared realm and can affect later suites. Retain this group's ID and delete it in the after hook as well.

    const group = await kcAdminClient.groups.create({
      name: "basic-group",
      attributes: {
        accessLevel: ["internal"],
        project: ["alpha"],
      },
    });

js/libs/keycloak-admin-client/test/groups.spec.ts:49

• The new basic-group is never deleted because the suite's after hook only removes currentGroup. This leaks state from the suite and makes repeated or filtered runs susceptible to stale groups and incorrect counts; delete this group after its assertions or track it for cleanup in the hook.

    const group = await kcAdminClient.groups.create({
      name: "basic-group",
      attributes: {
        accessLevel: ["internal"],
        project: ["alpha"],
      },
    });

js/libs/keycloak-admin-client/test/groups.spec.ts:50

• This test only verifies that some group was created, so it still passes if the client or server silently drops attributes. Read the group back by ID and assert that both attribute arrays were persisted.

    expect(group.id).to.be.ok;
