Question

只想从它自己的样本开始学习Selenium测试。但是，在设置完所有内容后（Node.js，Selenium），当我想使用selenium-webdriver自己的样本时，它无法正常工作：

这是由selenium提供的官方代码（名称为google_search.js）：

var webdriver = require('selenium-webdriver'),
    By = webdriver.By,
    until = webdriver.until;

var driver = new webdriver.Builder()
    .forBrowser('firefox')
    .build();

driver.get('http://www.google.com/ncr');
driver.findElement(By.name('q')).sendKeys('webdriver');
driver.findElement(By.name('btnG')).click();
driver.wait(until.titleIs('webdriver - Google Search'), 1000);
driver.quit();

此代码位于example文件夹中，位于Node.js cmd中，我cd到node_modules \ selenium-webdriver \ example，并将geckodriver放入此文件夹，然后运行node google_search.js 结果如下：

C:\Users\username\node_modules\selenium-webdriver\lib\promise.js:2291
        throw error;
        ^

WebDriverError: Unable to parse new session response: {"error":"unknown error","

 location, no 'firefox_binary' capability provided, and no binary flag set on th

我做错了什么吗？任何人都可以告诉我为什么官方样本没有启动Firefox？谢谢！

尝试使用Selenium 3.0.0运行C＃应用程序时，我收到了同样的错误消息。

问题是我使用的是x64 Geckodriver.exe。下载并将32位版本复制到我的bin文件夹后，一切运行良好。

使用Javascript和selenium自己的样本无法使用geckodriver 0.10在selenium 3.0-beta3中启动Firefox
