在Selenium的FirefoxOptions中设置BrowserExecutableLocation不会阻止“无法找到一组匹配的功能”错误

本文介绍了在Selenium的FirefoxOptions中设置BrowserExecutableLocation不会阻止“无法找到一组匹配的功能”错误的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 对于Selenium来说，我还是一个相当新的东西，并且正在尝试创建一些最低限度通过的测试用例（从某种意义上说，我想你可以称它们为hello world程序的对等）。 我尝试创建Firefox驱动程序的实例，如下所示： var options = new FirefoxOptions ） { BrowserExecutableLocation = @C：\ Program Files（x86）\ Mozilla Firefox \Firefox.exe， Profile = new FirefoxProfile（）， LogLevel = FirefoxDriverLogLevel.Debug }; firefoxDriver =新的FirefoxDriver（选项）; 但是，当我运行测试时，出现以下错误： Unable找到一组匹配的功能。我在堆栈溢出和其他地方读到的其他答案表明，解决这个问题的方法是显式指定二进制文件的位置，如下所示： firefoxDriver = new FirefoxDriver 当我尝试这种方法时，它可以工作，但是我得到了下面的编译器警告： 警告CS0618'FirefoxDriver.FirefoxDriver（FirefoxBinary，FirefoxProfile）'已经过时：'FirefoxDriver不能用FirefoxBinary对象构建。改用FirefoxOptions。这个构造函数将会在将来的版本中被移除。 如果第二个版本能够运行，为什么第一个版本不能运行，因为我在 FirefoxOptions 中清楚地指定了 BrowserExecutableLocation ？有没有一种方法可以使我像第一种方式尝试工作，以避免使用第二个，不赞成使用的构造函数？ $ b FWIW，我使用Firefox 52.2.0 ，我的NuGet包设置如下： < packages> < package id =Selenium.Firefox.WebDriverversion =0.18.0targetFramework =net452/> < package id =Selenium.WebDriverversion =3.4.0targetFramework =net452/> < package id =Selenium.WebDriver.IEDriverversion =3.4.0targetFramework =net452/> < / packages> 解决方案如果您尝试使用FirefoxOptions，这个构造函数： pre code> FirefoxDriver（FirefoxDriverService服务，FirefoxOptions选项，TimeSpan commandTimeout）; 对我而言，以下方法无效： FirefoxDriverService服务= FirefoxDriverService.CreateDefaultService（Path to Gecko）; service.FirefoxBinaryPath = @C：\ Program Files \Mozilla Firefox\firefox.exe; driver = new FirefoxDriver（service）; 然而，以下效果很好： FirefoxDriverService服务= FirefoxDriverService.CreateDefaultService（Gecko Path）; FirefoxOptions选项=新的FirefoxOptions（）; options.BrowserExecutableLocation = @C：\ Program Files \Mozilla Firefox\firefox.exe; driver = new FirefoxDriver（service，options，TimeSpan.FromMinutes（1））; I'm still fairly new to Selenium and am trying to create some minimally passing test cases (I guess you could call them the equivalent of a "hello world" program in a sense).I tried to create an instance of the Firefox Driver like this:var options = new FirefoxOptions(){ BrowserExecutableLocation = @"C:\Program Files(x86)\Mozilla Firefox\Firefox.exe", Profile = new FirefoxProfile(), LogLevel = FirefoxDriverLogLevel.Debug};firefoxDriver = new FirefoxDriver(options);However, when I ran the test, I got the following error: Unable to find a matching set of capabilities. Several other answers I read on Stack Overflow and elsewhere suggested that the way to fix this is to explicitly specify the location of the binary file, like this:firefoxDriver = new FirefoxDriver(new FirefoxBinary(@"C:\Program Files (x86)\Mozilla Firefox\firefox.exe"), new FirefoxProfile());When I try that, it works, but I get the following compiler warning:Warning CS0618 'FirefoxDriver.FirefoxDriver(FirefoxBinary, FirefoxProfile)' is obsolete: 'FirefoxDriver should not be constructed with a FirefoxBinary object. Use FirefoxOptions instead. This constructor will be removed in a future release.'If the second version works, why doesn't the first version work as well, given that I clearly specified the BrowserExecutableLocation in FirefoxOptions? Is there a way to make something like the first way I tried work in order to avoid using the second, deprecated constructor?FWIW, I'm using Firefox 52.2.0, and my NuGet packages are set as follows:<packages> <package id="Selenium.Firefox.WebDriver" version="0.18.0" targetFramework="net452" /> <package id="Selenium.WebDriver" version="3.4.0" targetFramework="net452" /> <package id="Selenium.WebDriver.IEDriver" version="3.4.0" targetFramework="net452" /></packages> 解决方案 If you are trying to use FirefoxOptions in particular, try this constructor:FirefoxDriver(FirefoxDriverService service, FirefoxOptions options, TimeSpan commandTimeout);For me the following did not work:FirefoxDriverService service = FirefoxDriverService.CreateDefaultService(Path to Gecko);service.FirefoxBinaryPath = @"C:\Program Files\Mozilla Firefox\firefox.exe";driver = new FirefoxDriver(service);However the following works well:FirefoxDriverService service = FirefoxDriverService.CreateDefaultService("Gecko Path");FirefoxOptions options = new FirefoxOptions();options.BrowserExecutableLocation = @"C:\Program Files\Mozilla Firefox\firefox.exe";driver = new FirefoxDriver(service, options, TimeSpan.FromMinutes(1)); 这篇关于在Selenium的FirefoxOptions中设置BrowserExecutableLocation不会阻止“无法找到一组匹配的功能”错误的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
