java - Selenium Webdriver 通信错误

Question

我正在做一个 java 项目，它使用 selenium web 驱动程序自动执行网站中的任务，但出现错误。

设置System.setProperty("webdriver.chrome.driver","chrome驱动程序的路径");

有这个方法

public boolean openBrowserAndLoadUrl(String url) {          
        ChromeOptions options = new ChromeOptions();
        options.addArguments("--disable-extensions","--start-maximized");
        WebDriver driver = new ChromeDriver(options);
        if(driver==null)
            return false;
        driver.get("https://www.google.co.in");
        driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
        return true;
}

pom.xml

<org.seleniumhq-version>2.53.1</org.seleniumhq-version>

<!-- Selenium -->
    <dependency>
        <groupId>org.seleniumhq.selenium</groupId>
        <artifactId>selenium-chrome-driver</artifactId>
        <version>${org.seleniumhq-version}</version>
    </dependency>
    <dependency>
        <groupId>org.seleniumhq.selenium</groupId>
        <artifactId>htmlunit-driver</artifactId>
        <version>2.23</version>
    </dependency>

“驱动程序”变量已初始化，并且 Google Chrome 已打开。 Eclipse 调试显示此处发生异常 driver.get("https://www.google.co.in");

两次出现两种类型的错误!两个堆栈跟踪如下所示。

org.openqa.selenium.remote.UnreachableBrowserException: Error communicating with the remote browser. It may have died.

后来我得到了这个错误

在进一步的研究中，我了解到很多人都有这个问题，但除了版本不兼容问题之外，我没有得到任何解决方案。但我正在使用下载的 chromedriver.exe

此外，早些时候，使用此 chrome 驱动程序和相同的 selenium 版本，所有 selenium 步骤均已成功。。不知道为什么现在变成这样了!请帮忙。

Answer 1

您的 Windows 系统中安装的 Chrome 浏览器可能已自动更新。
您可以从 Chrome 驱动程序网站下载最新的驱动程序。
