用于硒测试的Chrome移动模拟器-不能使用所有设备 [英] Chrome mobile emulator for Selenium testing- can't use all devices

问题描述

我正在使用Chrome驱动程序及其仿真器为移动设备进行Selify Java测试。问题是，我不能使用最先进的移动设备，如iPhone7，8等--尽管当我在DevTool中手动测试时，它在我的下拉列表中。 这是驱动程序初始化。这与许多移动设备完美配合：

if(browser.equalsIgnoreCase("mobileIPhone6")){
          Map<String, String> mobileEmulation = new HashMap<String, String>();
          mobileEmulation.put("deviceName", "iPhone 6");
          String exePathChromeDriver = Consts.chromeDriverPath;
          System.setProperty("webdriver.chrome.driver", exePathChromeDriver);
          PropertyLoader.loadCapabilities();
          ChromeOptions chromeOptions = new ChromeOptions();
          chromeOptions.setExperimentalOption("mobileEmulation", mobileEmulation);
          driver = new ChromeDriver(chromeOptions);

但是，当我将第3行更改为"iPhone 7"时，我收到以下错误：

2018-03-16 21:25:49 INFO  LogLog4j:210 - org.openqa.selenium.WebDriverException: unknown error: cannot parse capability: chromeOptions
from unknown error: cannot parse mobileEmulation
from unknown error: 'iPhone 7' must be a valid device
from unknown error: must be a valid device

你知道为什么吗？非常感谢

推荐答案

我已找到解决方案，现在工作正常。我必须首先设置Device Metrics对象：

...else if(browser.equalsIgnoreCase("iPhone678")){
      String exePathChromeDriver = Consts.chromeDriverPath;
      System.setProperty("webdriver.chrome.driver", exePathChromeDriver);

      Map<String, Object> deviceMetrics = new HashMap<>();
      deviceMetrics.put("width", 375);
      deviceMetrics.put("height", 667);
      deviceMetrics.put("pixelRatio", 2.0);

      Map<String, Object> mobileEmulation = new HashMap<>();
      mobileEmulation.put("deviceMetrics", deviceMetrics);
      mobileEmulation.put("userAgent", "Mozilla/5.0 (iPhone; CPU iPhone OS 11_0 like Mac OS X) AppleWebKit/604.1.34 (KHTML, like Gecko) Version/11.0 Mobile/15A5341f Safari/604.1");

      ChromeOptions chromeOptions = new ChromeOptions();
      chromeOptions.setExperimentalOption("mobileEmulation", mobileEmulation);
      driver = new ChromeDriver(chromeOptions); }
