Selenium 教程问题，如何解决我收到的许多错误？

Question

我目前正在学习 Selenium 教程 Here 并且我已经完全按照每个步骤进行操作，但是我的 Eclipse 程序一直在抛出错误。我使用的是 Selenium 3，而本教程适用于旧版本。除了这个，我找不到任何综合教程。如何修复以下代码中的错误？我已经评论了每一行之后我得到的确切错误。该代码已经包含了一些注释，因此请忽略行首的任何注释。其他一切都应该是错误信息。

我还需要知道如何使用 Eclipse 设置我的类路径，以允许它访问 GeckoDriver，这可能会或可能不会解决问题。

我认为我所做的只是将导入移到 class 之外并删除了一个 }，错误就消失了。我修复了缩进并删除了所有与错误相关的注释。试试这个...

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;

public class Gmail_Login
{
    public static void main(String[] args)
    {
        // objects and variables instantiation
        WebDriver driver = new FirefoxDriver();
        String appUrl = "https://accounts.google.com";

        // launch the firefox browser and open the application url
        driver.get(appUrl);

        // maximize the browser window
        driver.manage().window().maximize();

        // declare and initialize the variable to store the expected title of the webpage.
        String expectedTitle = " Sign in - Google Accounts ";

        // fetch the title of the web page and save it into a string variable
        String actualTitle = driver.getTitle();

        // compare the expected title of the page with the actual title of the page and print the result
        if (expectedTitle.equals(actualTitle))
        {
            System.out.println("Verification Successful - The correct title is displayed on the web page.");
        }
        else
        {
            System.out.println("Verification Failed - An incorrect title is displayed on the web page.");
        }

        // enter a valid username in the email textbox
        WebElement username = driver.findElement(By.id("Email"));
        username.clear();
        username.sendKeys("TestSelenium");

        // enter a valid password in the password textbox
        WebElement password = driver.findElement(By.id("Passwd"));
        password.clear();
        password.sendKeys("password123");

        // click on the Sign in button
        WebElement SignInButton = driver.findElement(By.id("signIn"));
        SignInButton.click();

        // close the web browser

我想我所做的一切都是将导入移到 class 之外并删除一个 } 并且错误消失了。我修正了缩进并删除了所有与错误相关的评论。尝试以下编码：

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;

public class Gmail_Login
{
    public static void main(String[] args)
    {
        // objects and variables instantiation
        WebDriver driver = new FirefoxDriver();
        String appUrl = "https://accounts.google.com";

        // launch the firefox browser and open the application url
        driver.get(appUrl);

        // maximize the browser window
        driver.manage().window().maximize();

        // declare and initialize the variable to store the expected title of the webpage.
        String expectedTitle = " Sign in - Google Accounts ";

        // fetch the title of the web page and save it into a string variable
        String actualTitle = driver.getTitle();

        // compare the expected title of the page with the actual title of the page and print the result
        if (expectedTitle.equals(actualTitle))
        {
            System.out.println("Verification Successful - The correct title is displayed on the web page.");
        }
        else
        {
            System.out.println("Verification Failed - An incorrect title is displayed on the web page.");
        }

        // enter a valid username in the email textbox
        WebElement username = driver.findElement(By.id("Email"));
        username.clear();
        username.sendKeys("TestSelenium");

        // enter a valid password in the password textbox
        WebElement password = driver.findElement(By.id("Passwd"));
        password.clear();
        password.sendKeys("password123");

        // click on the Sign in button
        WebElement SignInButton = driver.findElement(By.id("signIn"));
        SignInButton.click();

        // close the web browser
        driver.close();
        System.out.println("Test script executed successfully.");
        // terminate the program
        System.exit(0);
    }
}
