java - 当 marionette 通过 Selenium 3.12.0 变为 false 时，无法找到与 Firefox 匹配的功能集

Question

我已经正确设置了路径和firefox bin，但仍然不知道问题出在哪里。下面添加启动firefox驱动程序的代码:

System.setProperty("webdriver.gecko.driver", "/opt/config/x_conf_dir/geckodriver");
      System.setProperty("webdriver.firefox.bin", "/opt/config/x_conf_dir/firefox-bin");
      FirefoxOptions options = new FirefoxOptions();
      options.addArguments("start-maximized");
      options.addArguments("headless");
      options.addArguments("window-size=1200,1100");
      LOGGER.warn("Start initiating firefox driver");
      WebDriver driver = new FirefoxDriver(options);
      driver.manage().timeouts().implicitlyWait(50, TimeUnit.SECONDS);
      driver.get("https://stackoverflow.com");
      LOGGER.warn("Page title is {}", driver.getTitle());
      File scrFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
      FileUtils.copyFile(scrFile, new File("/opt/config/x_conf_dir/screen.png"));

在java中启动firefox驱动程序时，当marionette转为false时，它会给出此异常，否则它会给出“无法找到匹配的功能集”。

Answer 1

根据错误堆栈跟踪，您正在使用Selenium Java Client v3.12.0。所以你必须使用GeckoDriver和ma​​rionette作为强制措施。但默认情况下，ma​​rionette 设置为 true。

正如您提到的marionatte 变为 false 因此您看到的错误为:

• 工作代码:

  System.setProperty("webdriver.gecko.driver", "C:/path/to/geckodriver.exe");
  DesiredCapabilities dc = new DesiredCapabilities();
  dc.setCapability("marionatte", true);
  FirefoxOptions opt = new FirefoxOptions();
  opt.merge(dc);
  FirefoxDriver driver =  new FirefoxDriver(opt);
  driver.get("https://stackoverflow.com");
  

• 当您使用GeckoDriver时，marionatte 默认设置为true。在这种情况下，您还可以跳过 marionatte 功能，并使用以下解决方案:

  System.setProperty("webdriver.gecko.driver", "C:/path/to/geckodriver.exe");
  FirefoxDriver driver =  new FirefoxDriver();
  driver.get("https://stackoverflow.com");
  

• 您可以在 org.openqa.selenium.SessionNotCreatedException: Unable to find a matching set of capabilities while initiating Firefox v37 through Selenium v3.11.0 中找到详细讨论。
