Как решить проблему с "типом журнала" производительность "не найдена"?

Question

Я пытаюсь получить все сетевые вызовы (ajax и т. Д.) С помощью автоматизации селена для браузера Chrome.Я использую возможность «LoggingPreferences» для того же.Но я получаю приведенную ниже ошибку при попытке извлечь журналы вызовов.

log type 'performance' not found    

Я использую selenium-server-standalone-2.53.0 и chromedriver 2.40.Я запускаю свои тестовые случаи на Mac.

Возможности Код:

final DesiredCapabilities capabilities = new DesiredCapabilities();
    final List<String> chromeOptionArgs = new ArrayList<String>();
    final Map<String, Object> chromeOptions = new HashMap<>();

    chromeOptions.put("args", chromeOptionArgs);
    chromeOptions.put("mobileEmulation", ImmutableMap.of("deviceName",device.name));
    chromeOptionArgs.addAll(Arrays.asList("disable-extensions", "test-type", "no-default-browser-check",
            "ignore-certificate-errors"));
    LoggingPreferences logPrefs = new LoggingPreferences();
    logPrefs.enable(LogType.PERFORMANCE, Level.ALL);
    capabilities.setCapability(CapabilityType.LOGGING_PREFS, logPrefs);
    capabilities.setCapability(ChromeOptions.CAPABILITY, chromeOptions);
    return capabilities;

// Код для извлечения сетевых вызовов

Список les = getDriver (). Manage ().logs () получить (LogType.PERFORMANCE) .getAll ().

В идеале сетевые вызовы должны выбираться, а при загрузке журналов возникает ошибка:

 org.openqa.selenium.WebDriverException: unknown error: log type 'performance' not found

Этот код ниже работает для извлечения кода состояния с использованием Selenium.

        // easy to understand

Вы можете использовать ниже код для справки

public void public static void main(String[] args)
{    
    WebDriver driver = null;
     Map<String, String> mobileEmulation = new HashMap<>();
     mobileEmulation.put("deviceName", "Nexus 5");
     //this is just to lauch my browser in mobile view
     ChromeOptions op =  new ChromeOptions();
     op.setExperimentalOption("mobileEmulation", mobileEmulation);

    //this is to ENABLE LogType.PERFORMANCE
    DesiredCapabilities caps = DesiredCapabilities.chrome();
    LoggingPreferences logPrefs = new LoggingPreferences();
    logPrefs.enable(LogType.PERFORMANCE, Level.INFO);
    caps.setCapability(CapabilityType.LOGGING_PREFS, logPrefs);

    //this is to merge your desired capabilties with ChromeOptions (as ChromeDriver(capabilties) is suppressed)
    op.merge(caps); //THIS IS SOMETHING WHICH IS MISSING IN YOUR CODE

    //this is just to instantiate the driver and lauch my application
    driver = new ChromeDriver(op);
    driver.get("https://m.snapdeal.com/");

    //this is just to make you know user number of logs with LogType as PERFORMANCE
    List<LogEntry> entries = driver.manage().logs().get(LogType.PERFORMANCE).getAll();
    System.out.println(entries.size() + " " + LogType.PERFORMANCE + " log entries found");


    //as the request and response will consists HUGE amount of DATA so I will be write it into text file for reference
    for (LogEntry entry : entries) 
    {
        try 
        {
            FileWriter f = new FileWriter("pathOfYourFileWhereYouWantToWriteYourData", true);
            BufferedWriter bufferedWriter = new BufferedWriter(f);

            String data =  (new Date(entry.getTimestamp()) + " " + entry.getLevel() + " " + entry.getMessage()).toString();

            bufferedWriter.write(data);
            bufferedWriter.write("\n"+"@@@@@@@@@@"+"\n\n");
            bufferedWriter.close();
        } catch (IOException e) 
         {
            e.printStackTrace();
         }
    }

 }
