### Question:
Station { public void connectToServer(String serverBaseUrl) { String stationWebSocketUrl = serverBaseUrl + "/" + configuration.getId(); webSocketClient.connect(stationWebSocketUrl); } Station(SimulatorConfiguration.StationConfiguration stationConfiguration);  Station(SimulatorConfiguration.StationConfiguration stationConfiguration, SimulatorConfiguration.WebSocketConfiguration socketConfiguration); void connectToServer(String serverBaseUrl); void run(); void stop(); void sendMessage(StationMessage stationMessage); Future<UserMessageResult> executeUserCommand(UserMessage userCommand, int timeOutSec); StationStoreView getStateView(); SimulatorConfiguration.StationConfiguration getConfiguration(); void updateHeartbeat(int newHeartbeatInterval); void updateEVConnectionTimeOut(int newEVConnectionTimeOut); void updateTxStartPointValues(OptionList<TxStartStopPointVariableValues> txStartPointValues); void updateTxStopPointValues(OptionList<TxStartStopPointVariableValues> txStopPointValues); void updateNetworkConfigurationPriorityValues(Integer networkConfigurationPriorityValues); String getId(); void reconnect(); void reconnect(long timeout, TimeUnit unit); void switchToSecurityProfile3(String url);  }### Answer:
@Test void verifyConnectionUrl() { station.connectToServer(SERVER_BASE_URL); ArgumentCaptor<String> urlCapture = ArgumentCaptor.forClass(String.class); verify(webSocketClientMock).connect(urlCapture.capture()); String expectedUrl = SERVER_BASE_URL + "/" + STATION_ID; assertEquals(expectedUrl, urlCapture.getValue()); }
