为什么在尝试使用 Selenium 打开网站时出现 GridException

Question

我是硒新手。

这就是我所做的： 我在 cmd 提示符下启动了一个独立的 selenium 服务器。

我在下面的代码中运行，对于 webDriverWay() 和 seleniumWay()，我得到如下错误。在这两种情况下，我都会得到 ​​p>

我的测试代码：

static String baseUrl= "http:\\google.com" ;

public static void main(String[] args) throws MalformedURLException {

    //webDriverWay();
    seleniumWay();

}

private static void webDriverWay() throws MalformedURLException {
    URL url = new URL("http://127.0.0.1:4444/wd/hub"); //Could be your remote VM where you to run your tests

    DesiredCapabilities capabilities;
    capabilities = DesiredCapabilities.firefox();

    //You can test multiple type of browser
    //capabilities = DesiredCapabilities.internetExplorer();
    WebDriver driver = new RemoteWebDriver(url, capabilities);

    //Open the web site
    driver.get(baseUrl);

    //Type Search Term
    (driver.findElement(By.name("q"))).sendKeys("Test Search Query");

    //Click submit button
    (driver.findElement(By.name("btnG"))).click();
}


static void seleniumWay()
{
    Selenium sel = new DefaultSelenium("localhost", 4444, "*firefox", baseUrl);
    CommandExecutor executor = new SeleneseCommandExecutor(sel);
    DesiredCapabilities dc = new DesiredCapabilities();
    WebDriver browser = new RemoteWebDriver(executor, dc);

    browser.get(baseUrl);
    WebElement input = browser.findElement(By.name("q"));
    input.sendKeys("Selenium");
}

控制台异常：

Exception in thread "main" org.openqa.selenium.WebDriverException: Could not start Selenium session: org.openqa.grid.common.exception.GridException: Error forwarding the new session Empty pool of VM for setup {browserName=*safari}

如果我遗漏了什么，请告诉我。

guide 包含配置测试所需的所有信息。当我自己第一次开始使用 Selenium 时，我遇到了一个非常相似的问题。
