Webdriver 3.0.0-beta3无法与浏览器交互

Question

我正在研究硒自动化。今天我更新了我的pom文件以获得最新的依赖项。

<dependency>
        <groupId>org.seleniumhq.selenium</groupId>
        <artifactId>selenium-java</artifactId>
        <version>3.0.0-beta3</version>
    </dependency>
    <dependency>
        <groupId>org.seleniumhq.selenium</groupId>
        <artifactId>selenium-firefox-driver</artifactId>
        <version>3.0.0-beta3</version>
    </dependency>

在此之后，我的测试都没有在浏览器上运行。假设firefox在48版本上打开，但是webdriver没有与浏览器交互。我得到的错误日志是：

org.openqa.selenium.WebDriverException: Failed to connect to binary FirefoxBinary

这是我在今天早上将64位机器上的jre和jdk更改为32位后出现的新错误

Answer 1

这是Selenium3和Mozilla Firefox版本之间的不兼容问题。

实际上Selenium3支持可执行的geckodriver，就像其他驱动程序一样启动Mozilla Firefox >= v47。

To work around you need to download latest executable geckodriver and extract downloaded zip into your system at any location并设置Syetem属性与webdriver.gecko.driver指向下载可执行geckodriver位置如下： -

System.setProperty("webdriver.gecko.driver", "path/to/geckodriver");

WebDriver driver = new FirefoxDriver();
