在Saucelabs中使用Selenium远程Firefox webdriver安装扩展程序 [英] Issue installing extension with Selenium remote Firefox webdriver in Saucelabs

问题描述

问题

尝试在Saucelabs上远程执行Selenium测试期间安装Firefox浏览器扩展。在本地执行测试时，扩展程序在Firefox中安装并处于活动状态，但在Saucelabs上的远程执行中，扩展名不会出现在已安装的扩展名列表中。按照此Saucelabs中列出的步骤支持文章。

设置

Selenium.Support v2.48.2或v2.49.0

Selenium.WebDriver v2.48.2或v2.49.0

Windows 10或7

Firefox 43

Setup
Selenium.Support v2.48.2 or v2.49.0
Selenium.WebDriver v2.48.2 or v2.49.0
Windows 10 or 7
Firefox 43

C＃测试设置

private static FirefoxProfile CreateFirefoxProfile()
    {
        FirefoxProfile profile = new FirefoxProfile();
        profile.AddExtension("Tools/modify_headers-0.7.1.1-fx.xpi");
        profile.SetPreference("general.useragent.override", "UA-STRING");
        profile.SetPreference("extensions.modify_headers.currentVersion", "0.7.1.1-signed");
        profile.SetPreference("modifyheaders.headers.count", 1);
        profile.SetPreference("modifyheaders.headers.action0", "Add");
        profile.SetPreference("modifyheaders.headers.name0", "SampleHeader");
        profile.SetPreference("modifyheaders.headers.value0", "test1234");
        profile.SetPreference("modifyheaders.headers.enabled0", true);
        profile.SetPreference("modifyheaders.config.active", true);
        profile.SetPreference("modifyheaders.config.alwaysOn", true);
        profile.SetPreference("modifyheaders.config.start", true);

        return profile;
    }

private static IWebDriver GetRemoteDriver()
    {
        var capabilities = new DesiredCapabilities();

        var profile = CreateFirefoxProfile();

        capabilities.SetCapability(FirefoxDriver.ProfileCapabilityName, profile);

        capabilities.SetCapability("name", buildContext);
        capabilities.SetCapability(CapabilityType.BrowserName,"firefox");
        capabilities.SetCapability(CapabilityType.Version,"");
        capabilities.SetCapability(CapabilityType.Platform, "Windows 10");
        capabilities.SetCapability("screen-resolution", "1280x1024");
        capabilities.SetCapability("username", "SaucelabsUserName");
        capabilities.SetCapability("accessKey", "SaucelabsAccessKey");
        capabilities.SetCapability("build", "BuildNumber");

        return new RemoteWebDriver(new Uri("http://ondemand.saucelabs.com/wd/hub"), capabilities);
    }

Firefox设置

在本地执行期间查看：支持Firefox并打开user.js文件时，它包含以下与Web驱动程序配置匹配的扩展设置。检查Saucelabs远程实例上的user.js不包含该内容。这是远程user.js文件内容的粘贴bin 。

user_pref("general.useragent.override", "UA-STRING");
user_pref("extensions.modify_headers.currentVersion", "0.7.1.1-signed");
user_pref("modifyheaders.headers.count", 1);
user_pref("modifyheaders.headers.action0", "Add");
user_pref("modifyheaders.headers.name0", "SampleHeader");
user_pref("modifyheaders.headers.value0", "test1234");
user_pref("modifyheaders.headers.enabled0", true);
user_pref("modifyheaders.config.active", true);
user_pref("modifyheaders.config.alwaysOn", true);
user_pref("modifyheaders.config.start", true);

我也尝试过引用xpi的外部版本，结果相同。
https://addons.mozilla.org /firefox/downloads/latest/967/addon-967-latest.xpi

I've also tried referencing an external version of the xpi with same result. https://addons.mozilla.org/firefox/downloads/latest/967/addon-967-latest.xpi

推荐答案

发表了错误报告到SeleniumHQ并收到此回复，修复了上述代码。

Posted a bug report to SeleniumHQ and received this response, which fixed the above code.

在.NET的RemoteWebDriver情况下，您需要使用
ToBase64String（）方法。这应该可以解决问题。请注意，这个
是其他驱动程序具有类型安全选项
类而不是传递原始功能的原因之一。
.NET绑定的未来版本也应该将此模式扩展到Firefox，将此作为一个问题删除
。

In the RemoteWebDriver case for .NET, you need to use the ToBase64String() method. This should resolve the issue. Note that this is one of the reasons that other drivers have type-safe options classes instead of passing raw capabilities. Future versions of the .NET bindings should extend this pattern to Firefox as well, removing this as an issue in the future.

上面的GetRemoteDriver方法应该更新为。

The GetRemoteDriver method from above should be updated to this.

private static IWebDriver GetRemoteDriver()
{
    var capabilities = new DesiredCapabilities();

    var profile = CreateFirefoxProfile();

    // Note the change here, calling .ToBase64String()
    capabilities.SetCapability(FirefoxDriver.ProfileCapabilityName, profile.ToBase64String());

    capabilities.SetCapability("name", buildContext);
    capabilities.SetCapability(CapabilityType.BrowserName,"firefox");
    capabilities.SetCapability(CapabilityType.Version,"");
    capabilities.SetCapability(CapabilityType.Platform, "Windows 10");
    capabilities.SetCapability("screen-resolution", "1280x1024");
    capabilities.SetCapability("username", "SaucelabsUserName");
    capabilities.SetCapability("accessKey", "SaucelabsAccessKey");
    capabilities.SetCapability("build", "BuildNumber");

    return new RemoteWebDriver(new Uri("http://ondemand.saucelabs.com/wd/hub"), capabilities);
}
