org.openqa.selenium.SessionNotCreatedException：通过 Selenium v3.11.0 启动 Firefox v37 时无法找到匹配的功能集
org.openqa.selenium.SessionNotCreatedException: Unable to find a matching set of capabilities while initiating Firefox v37 through Selenium v3.11.0
我正在尝试 运行 在 Firefox 中测试一个 运行 网站，但出现错误 "The path to the driver executable must be set by the webdriver.gecko.driver system property;" 我已经正确设置了路径，但仍然不知道路径在哪里问题是。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：

系统 属性 是这样设置的：
System.setProperty("webdriver.gecko.driver", "C:\...\geckodriver.exe");
您正在使用 user.dir 这基本上意味着：当前工作目录
这是让您使用 selenium 初始化 firefox 浏览器的代码。
public static void main(String[] args) {
System.setProperty("webdriver.gecko.driver", "C:\your\gecko\driver\path\geckodriver.exe");
driver = new firefoxDriver();
就是这样！您可以使用 Firefox 驱动程序执行多种操作，例如：
1. driver.get(String args0);
2. driver.getCurrentUrl();
3. driver.getPageSource();
4. driver.getTitle();
5. driver.findElememt(By args0);
6. driver.findElements(By args0);
7. driver.naviagate();
8. driver.manage();
9. driver.close();
10. driver.quit();
11. driver.switchTo();
12. driver.getWindowHandle();
13. driver.getWindowHandles();
如果您对此有任何疑虑，请告诉我。
刚刚更新了您的代码。您必须设置驱动程序路径，而 setProperty 和用户 webdriver.gecko.driver 以获得最新的 firefox 驱动程序。
if (browsers.equalsIgnoreCase("Firefox")) {
String driverPath = System.getProperty("user.dir") + "\src\test\java\drivers\geckodriver.exe";
System.setProperty("webdriver.firefox.driver", "driverPath");
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability("marionette", false);
FirefoxOptions options = new FirefoxOptions();
options.merge(capabilities);
FirefoxDriver driver = new FirefoxDriver(options);
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);
}
告诉我。
为简单起见，由于您使用的是 Selenium Client v3.11.0 和 Firefox v37，您需要下载最新的 GeckoDriver 来自 mozilla/geckodriver 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 以及 Value作为GeckoDriver的绝对路径最后通过DesiredCapabilitiesclass设置capability marionatte 到 false 并合并到 FirefoxOptions 实例中以启动 Firefox 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://whosebug.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：
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：
- GeckoDriver v0.17.0
- GeckoDriver v0.16.1
我有 2 天遇到这个错误，我的解决方案是 Set.Platform，输入 Platform.ANY 或 Platform.Windows 因为 Platform.WIN10 不工作，marionette 不工作没必要。
public class Main { public static RemoteWebDriver driver;
public static void main(String[] args) throws MalformedURLException {
System.setProperty("webdriver.gecko.driver", "D:/Lib/geckodriver.exe");
DesiredCapabilities desiredCapabilities = new
DesiredCapabilities().firefox();
desiredCapabilities.setPlatform(Platform.ANY);
desiredCapabilities.setBrowserName("firefox");
driver = new RemoteWebDriver(new URL("http://172.20.19.182:5557/wd/hub"),
desiredCapabilities);
driver.navigate().to("http://www.google.com");
driver.findElementByName("q").sendKeys("execute automation");
driver.findElementByName("q").sendKeys(Keys.ENTER);
driver.close();
// write your code here
