Question

我使用简单的NodeJS脚本来测试google.com。使用了phantomJS浏览器。

var webdriver = require('selenium-webdriver');
var assert = require('assert');

var driver = new webdriver.Builder().
withCapabilities({
    browserName : "phantomjs"
}).
usingServer('http://127.0.0.1:4444/wd/hub').build();

//driver.manage().timeouts().implicitlyWait(60000);

driver.get('http://www.google.com');
driver.findElement(webdriver.By.xpath('//*[@id="gbqf"]')).sendKeys('webdriver');
driver.findElement(webdriver.By.name('btnG')).click();
driver.getTitle().then(function(title) {
    assert.equal("webdriver - Google Search", title);
 });

driver.quit();

使用

运行独立的selenium服务器

> java -jar selenium-server-standalone-2.35.0.jar

使用node命令并行运行脚本。

我收到以下错误

Answer 1

页面是否有可能没有完全加载，因为我知道当我去google.com时，它会将我重定向到我当地的google.co.uk网站。

严格用于调试目的，在findElement命令之前放置5秒的睡眠。如果那样有效，请用webdriverWait替换，直到对象出现在屏幕上。

但是，我也注意到您正在将密钥发送到“form”元素。这会有用吗？您不想将密钥发送到输入字段吗？

Answer 2

断言您实际上是在调用findElement命令之前希望处于的URL上。

错误消息：无法在phantomJS中找到带有xpath的元素
