org.openqa.selenium.SessionNotCreatedException:在通过 Selenium v3.11.0 启动 Firefox v37 时无法找到一组匹配的功能 [英] org.openqa.selenium.SessionNotCreatedException: Unable to find a matching set of capabilities while initiating Firefox v37 through Selenium v3.11.0
问题描述
我正在尝试在 Firefox 中运行测试和运行网站，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，仍然不知道问题出在哪里.这是我的代码:
I am trying to run test a run a website in Firefox, but I am getting error "The path to the driver executable must be set by the webdriver.gecko.driver system property;" I have set the path correctly, still don't know where the problem is. Here is my code:
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:

推荐答案
为了简单起见，当您使用 Selenium Client v3.11.0 和 Firefox v37 时，您需要从 mozilla/geckodriver<下载最新的 GeckoDriver/a> 并将其保存在系统中的任何位置.接下来在 System.setProperty() 行中传递 Key webdriver.gecko.driver 和 Value 作为GeckoDriver 的绝对路径，最后通过DesiredCapabilities 类将能力marionatte 设置为false 并合并到 FirefoxOptions 实例的一个实例中以启动 Firefox 浏览器，如下所示:
To keep things simple, as you are using Selenium Client v3.11.0 and Firefox v37 you need to download the latest GeckoDriver from mozilla/geckodriver and save it any where within your system. Next within the System.setProperty() line pass the Key webdriver.gecko.driver along with the Value as the absolute path of the GeckoDriver and finally through DesiredCapabilities class set the capability marionatte to false and merge into an instance of FirefoxOptions instance to initiate the Firefox browser as follows :
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
根据您的评论更新，您正在使用 GeckoDriver v0.20.1.
但是如果你回顾一下 GeckoDriver v0.18.0 的发行说明，它清楚地提到:
But if you look back at the Release Notes of GeckoDriver v0.18.0 it clearly mentions :
geckodriver now recommends Firefox 53 and greater
因此，使用 GeckoDriver v0.18.0 及更高版本，您必须强制使用 Firefox 53 及更高版本.要摆脱此限制，您可以降级到以下任一版本:
So using GeckoDriver v0.18.0 and above you have to mandatory use Firefox 53 and greater. To get rid of this constraint you can downgrade either to any of these versions :
- GeckoDriver v0.17.0
- GeckoDriver v0.16.1
