标签： junit automated-tests selenium-rc

我正在尝试运行从Selenium IDE导出的Junit测试用例。我超越了异常。我正在使用Windows XP，Firefox 20.0.1，并使用selenium-server-standalone-2.28.0.jar.Upon运行，打开一个空白的Firefox窗口。当我关闭该窗口时，我在控制台

中得到以下异常

您的Selenium版本可能与您的Firefox版本不兼容。尝试安装较旧的Firefox版本。

  1. 在安装和旧版本之前，请进入Firefox并关闭自动更新选项。

    Firefox - ＆gt;选项 - ＆gt;选项 - ＆gt;高级 - ＆gt;更新 - ＆gt;检查更新，但让我选择安装

  2. 转到此处并安装旧版本。 https://ftp.mozilla.org/pub/mozilla.org/firefox/releases/

    您不必卸载Firefox，只需安装要安装的版本即可。在获得正确版本之前，您可能需要尝试几个版本。

我刚刚使用maven为WebDriver设置了JBehave这个问题。我强迫JBehave以下列方式使用更高版本的硒，这对我有用：

<dependency>
    <groupId>org.jbehave.web</groupId>
    <artifactId>jbehave-web-selenium</artifactId>
    <version>${jbehave.web.version}</version>
    <exclusions>
        <exclusion>
            <groupId>org.seleniumhq.selenium</groupId>
            <artifactId>selenium-java</artifactId>
        </exclusion>
    </exclusions>
</dependency>
<dependency>
    <groupId>org.seleniumhq.selenium</groupId>
    <artifactId>selenium-java</artifactId>
    <version>2.33.0</version>
</dependency>

答案 2 :(得分：1)

所有提及的解决方案都不适用于我。对我有用的是使用最新的Firefox（目前是32.0.2）和最新的selenium 

    <dependency>
        <groupId>org.seleniumhq.selenium</groupId>
        <artifactId>selenium-java</artifactId>
        <version>2.43.1</version>
    </dependency>

版本2.43.1工作，2.42.1没有。

答案 3 :(得分：0)

我有完全相同的问题，我通过将Firefox版本降级到27.0.1

解决了这个问题

答案 4 :(得分：0)

当WebDriver版本与Firefox版本不匹配时，java编译器会抛出此错误。确保您的WebDriver和Firefox都是最新版本。

答案 5 :(得分：0)

更新到selenium-server-standalone-2.44.0.jar适用于我（http://www.seleniumhq.org/download/）。

您似乎需要浏览器，selenium-driver和selenium-server的正确组合。

Ubuntu 14.04，Firefox 35.0.1和selenium-webdriver 2.44.0适用于Ruby on Rails应用程序。 自从我更新Chrome后，Chrome就无法运行，即使使用上次发布的驱动程序也是如此。

答案 6 :(得分：-3)

您需要卸载当前安装的Firefox。使用最低版本18.0.1重新安装FF这确实有效。
