我无法运行包含HtmlUnitDriver的基本selenium脚本。如果我尝试运行代码,我会收到以下错误。
代码:
public class SampleUnitDriver
{
public static void main(String[] args) throws Exception
{
HtmlUnitDriver unitDriver = new HtmlUnitDriver();
unitDriver.get("http://google.com");
System.out.println("Title of the page is -> " + unitDriver.getTitle());
Thread.sleep(3000L);
WebElement searchBox = unitDriver.findElement(By.className("gsfi"));
searchBox.sendKeys("Selenium");
WebElement button = unitDriver.findElement(By.name("gbqfba"));
button.click();
System.out.println("Title of the page is -> " + unitDriver.getTitle());
}
}
错误:
Title of the page is -> Google

答案 0 :(得分:0)
输入框的类名gsfi
由javascript生成,因此您有2个选项:
Easy One:只需使用ID lst-ib
更好的一个:等待元素完全交互。这个更好的原因是你试图在javascript扮演角色的框中输入文本。前一个选项可能会引发一些意外错误。
