java.lang.ClassNotFoundException:WebDriver API

我下载了selenium-java-2.0a5.zip

并运行以下代码：

package org.openqa.selenium.example;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.htmlunit.HtmlUnitDriver;

public class Example  {
    public static void main(String[] args) {
        // Create a new instance of the html unit driver
        // Notice that the remainder of the code relies on the interface, 
        // not the implementation.
        WebDriver driver = new HtmlUnitDriver();

        // And now use this to visit Google
        driver.get("http://www.google.com");

        // Find the text input element by its name
        WebElement element = driver.findElement(By.name("q"));

        // Enter something to search for
        element.sendKeys("Cheese!");

        // Now submit the form. WebDriver will find the form for us from the element
        element.submit();

        // Check the title of the page
        System.out.println("Page title is: " + driver.getTitle());
    }
}

但后来我

我漏了一步吗？我确保将selenium-java-2.0a5.jar导入到项目中。

您似乎在项目中使用了“HtmlUnit”，而其jar在类路径中丢失。

---

添加selenium时将其添加到项目属性中。

htmlunit jar不在类路径中。还包括selenium-java-2.0a5.jar的依赖项库jar。我确信它们一定是在您下载的zip中提供的，您想从中下载selenium-server-standalone-2.0a5.jar，因为这包括依赖项。

检查我的答案。您忘记将HtmlUnit的jar添加到类路径。
