Question

我是使用带有TestNG的EclipseIDE的Selenium WebDriver的新手。我目前正通过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：

[TestNG] Running:

我不明白为什么我收到这个错误。我做了以下事情：

在Eclipse中添加了guava-12.0.jar文件（以及Selenium-2.25.0 webdriver中的其他jar文件）作为外部jar文件。（此jar文件包含ImmutableList $ Builder类）
在CLASSPATH中添加了此jar文件的路径（环境变量＆gt;系统变量）

我错过了什么吗？非常感谢任何帮助。

Answer 1

我猜你使用的是selenium-java-2.25.0.jar。您应该使用 selenium-server-standalone-2.25.0.jar，它将处理所有依赖项（即所需的jar文件）。

如果在Eclipse中添加了jar文件，你也不需要显式定义环境变量，除非你在eclipse之外运行测试。

希望这有助于...... :)
