找不到驱动程序类: com.opera.core.systems.OperaDriver

Question

尝试将节点分配给Selenium Grid时出现以下异常。并且此节点不会显示在网格控制台中。你知道为什么我会得到这个异常吗？

java -jar selenium-server-standalone-2.48.2.jar -port 5555 -role node -hub http://localhost:4444/grid/register

首先，我会选择Safari而不是Opera。其次，确保Selenium Safari和Opera驱动程序出现在您的依赖项中。您可以像这样显式定义它：

<dependency>
    <groupId>org.seleniumhq.selenium</groupId>
    <artifactId>selenium-safari-driver</artifactId>
    <version>2.48.2</version>
</dependency>

但是，您基本上需要做的是像这样配置Grid节点，并针对Mac进行调整。这是我对配置的猜测。您需要调整它。：

{
    "capabilities" : [{
            "browserName" : "firefox",
            "acceptSslCerts" : true,
            "javascriptEnabled" : true,
            "takesScreenshot" : false,
            "firefox_profile" : "",
            "browser-version" : "42",
            "platform" : "MAC",
            "maxInstances" : 5,
            "firefox_binary" : "",
            "cleanSession" : true
        }, {
            "browserName" : "chrome",
            "maxInstances" : 5,
            "platform" : "MAC",
            "webdriver.chrome.driver" : "/Applications/Opera.app/Contents/MacOS/Chrome/chrome"
        }, {
            "browserName" : "safari",
            "maxInstances" : 1,
            "platform" : "MAC",
            "version" : "12",
            "webdriver.safari.driver" : "
https://code.google.com/p/selenium/wiki/OperaDriver 
http://selenium-release.storage.googleapis.com/2.48/SafariDriver.safariextz"
        }, {
            "browserName" : "opera",
            "maxInstances" : 1,
            "platform" : "MAC",
            "version" : "8",
            "webdriver.opera.driver" : "???"
        }
    ],
    "configuration" : {
        "_comment" : "Configuration for Node",
        "cleanUpCycle" : 2000,
        "timeout" : 30000,
        "proxy" : "org.openqa.grid.selenium.proxy.WebDriverRemoteProxy",
        "port" : 5555,
        "host" : ip,
        "register" : true,
        "hubPort" : 4444,
        "maxSessions" : 5
    }
}
