只想从自己的样本开始学习 Selenium 测试。但是,在一切都设置好之后(Node.js,Selenium),当我想使用 selenium-webdriver 自己的示例时,它不起作用:
这是 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();
此代码在example
文件夹中,在 Node.js cmd 中,我 cd 到 node_modules\selenium-webdriver\example,并将 geckodriver 放在此文件夹中,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","

我做错什么了吗?谁能告诉我为什么官方样本没有启动 Firefox?谢谢!
