### Question:
OIDCCredentials { public boolean renew() throws AuthenticationException { throw new UnsupportedOperationException("Not yet implemented"); } OIDCCredentials(final String serialisedCredential);  OIDCCredentials(); String getAccessToken(); String getIdentityToken(); String getRefreshToken(); AuthState getAuthState(); boolean verifyClaims(final JsonWebKeySet jwks,
                    final KeycloakConfiguration keycloakConfig); boolean isExpired(); boolean getNeedsRenewal(); void setNeedsRenewal(); boolean isAuthorized(); String serialize(); static OIDCCredentials deserialize(final String serializedCredential); boolean checkValidAuth(); boolean renew(); @Override boolean equals(Object o); @Override int hashCode();  }### Answer:
@Test(expected = UnsupportedOperationException.class) public void testRenew() throws AuthenticationException { OIDCCredentials testCredential = new OIDCCredentials(CREDENTIAL_AUTH_STATE); testCredential.renew(); }
