Performance 启用Chromedriver’；s在Appium中的性能日志记录（仅限Chrome和webview）

使用Appium（AndroidDriver）从LogType获取性能日志会产生异常。 如果使用常规RemoteWebDriver/ChromeDriver对象，则会生成性能日志。而Appium还提供了“enablePerformanceLogging”标志来捕获Android webview的性能日志。但在启用此标志后，性能日志也不会被捕获

下面的代码使用RemoteWebDriver/Chrome生成性能日志：

DesiredCapabilities caps = DesiredCapabilities.chrome();
if (null != androidPackage) {
    ChromeOptions chromeOptions = new ChromeOptions();
    chromeOptions.setExperimentalOption("androidPackage", androidPackage);
    caps.setCapability(ChromeOptions.CAPABILITY, chromeOptions);
}
LoggingPreferences logPrefs = new LoggingPreferences();
logPrefs.enable(LogType.BROWSER, Level.ALL);
logPrefs.enable(LogType.PERFORMANCE, Level.INFO);
caps.setCapability(CapabilityType.LOGGING_PREFS, logPrefs);

ChromeDriverService service = new ChromeDriverService.Builder()
        .usingDriverExecutable(new File("/Users/abc/Desktop/driver/chromedriver"))
        .usingAnyFreePort()
        .build();
service.start();
driver = new RemoteWebDriver(service.getUrl(),
        caps);

检查可用的日志类型：

Logs logs = driver.manage().logs();
System.out.println("Log types: " + logs.getAvailableLogTypes());

Logs logs = driver.manage().logs();
System.out.println("Log types: " + logs.getAvailableLogTypes());

O/p:

不使用AndroidDriver（Appium）生成性能日志：

检查可用的日志类型：

Logs logs = driver.manage().logs();
System.out.println("Log types: " + logs.getAvailableLogTypes());

Logs logs = driver.manage().logs();
System.out.println("Log types: " + logs.getAvailableLogTypes());

O/p:

执行以下行导致异常，因为性能日志类型不可用：

List<LogEntry> entries = driverObj.manage().logs().get(LogType.PERFORMANCE).getAll();
