我是使用 EclipseIDE 和 TestNG 的 Selenium WebDriver 新手。我目前正在通过 TestNG 在 Eclipse 中运行此示例代码:
import org.openqa.selenium.By;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.annotations.AfterTest;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.Test;
import java.util.List;
public class CheesecakeFactory {
FirefoxDriver driver;
@BeforeTest
public void startDriver() {
driver = new FirefoxDriver();
}
@AfterTest
public void stopDriver() {
driver.close();
}
@Test
public void listCheesecakes() {
driver.get("http://www.thecheesecakefactory.com/");
driver.findElement(By.linkText("Menu")).click();
driver.findElement(By.linkText("Cheesecake")).click();
List<WebElement> cheesecakes = driver.findElements(By.xpath("id('leftNav_levelTwo')//li"));
System.out.println(cheesecakes.size() + " cheesecakes:");
for (int i=0; i<cheesecakes.size(); i++) {
System.out.println(i+1 + ". " + cheesecakes.get(i).getText());
}
}
}
但是 Eclipse 会返回这个:

我不明白为什么我会收到这个错误。我做了以下事情:
添加了 guava-12.0.jar 文件(以及 Selenium-2.25.0 webdriver 中的其他 jar 文件)作为 Eclipse 中的外部 jar 文件。(这个 jar 文件包含 ImmutableList$Builder 类)
在CLASSPATH中添加了这个jar文件的路径(Environment Variables>System Variables)
我错过了什么吗?任何帮助是极大的赞赏。
