如何解决org.openqa.selenium.SessionNotCreatedException：通过Selenium v3.11.0启动Firefox v37时，找不到匹配的功能集
为了简化操作，在使用 Selenium Client v3.11.0 和 Firefox v37时， 您需要从 下载最新的GeckoDriver 并将其保存在系统中的任何位置。接下来，在该行中传递 Key _____浏览器如下：
System.setProperty("webdriver.gecko.driver", "C:/path/to/geckodriver.exe");
DesiredCapabilities dc = new DesiredCapabilities();
dc.setCapability("marionatte", false);
FirefoxOptions opt = new FirefoxOptions();
opt.merge(dc);
FirefoxDriver driver = new FirefoxDriver(opt);
driver.get("https://stackoverflow.com");
System.out.println("Application opened");
System.out.println("Page Title is : "+driver.getTitle());
driver.quit();
更新资料
根据您的评论更新，您正在使用 。
但是，如果您回顾一下 的发行说明，它显然会提到：
geckodriver now recommends Firefox 53 and greater
因此，使用 及更高版本，您必须强制使用Firefox 53及更高版本。要摆脱这种限制，您可以降级到以下任一版本：
解决方法
我试图在Firefox中运行网站进行测试，但出现错误“驱动程序可执行文件的路径必须由webdriver.gecko.driver系统属性设置；”
我已经正确设置了路径，但仍然不知道问题出在哪里。这是我的代码：
if (browsers.equalsIgnoreCase("Firefox"))
{
String driverPath = System.getProperty("user.dir") + "\\src/test/java\\drivers\\geckodriver.exe";
System.setProperty("webdriver.firefox.marionette","false");
driver = new FirefoxDriver();
driver.manage().timeouts().implicitlyWait(30,TimeUnit.SECONDS);
} else if (browsers.equalsIgnoreCase("Chrome")) {
// String driverPath = System.getProperty("user.dir") +
// "\\src\\Drivers\\chromedriver";
// System.setProperty("webdriver.chrome.driver",driverPath);
System.setProperty("webdriver.chrome.driver","D:\\chromedriver.exe");
driver = new ChromeDriver();
driver.manage().timeouts().implicitlyWait(30,TimeUnit.SECONDS);
}
这是我的代码的失败跟踪：
