### Question:
AuthStateManager { public OIDCCredentials load() { final String currentState = prefs.getString(KEY_STATE, null); if (currentState == null) { return new OIDCCredentials(); } return OIDCCredentials.deserialize(currentState); } private  AuthStateManager(final Context context); OIDCCredentials load(); synchronized void save(final OIDCCredentials authState); synchronized void clear(); static AuthStateManager getInstance();  }### Answer:
@Test public void testLoadWithEmptyStore() { OIDCCredentials authState = authStateManager.load(); assertNull(authState.getAccessToken()); assertNull(authState.getIdentityToken()); assertNull(authState.getRefreshToken()); }
