Cucumber Scenario Outline仅执行第一组数据问题排查

我是Cucumber新手，正在学习自动化测试。编写了包含Scenario Outline和Examples表的Demo.feature文件，表内有3组登录测试凭证，但运行后仅执行第一组数据，控制台显示仅1个Scenario执行成功，其余两组未运行，请求协助排查解决该问题。

相关代码文件

Demo.feature

Feature: Test login functionality

Scenario Outline: Check login is successful with valid credentials
Given browser is open
And user is on login page
When user enters <username> and <password>
And user clicks on login
Then user is navigated to the home page

Examples: 
  | username | password    |
  | student  | Password123 |
  | Raghav   | pass123     |
  | dil      | dill2       |

该表仅运行第一组用户名和密码，未执行全部3组数据。

问题原因及解决方案

问题根源

在LoginDemoSteps类的@Then步骤方法中，执行了driver.quit()——该方法会彻底终止整个WebDriver会话。第一组数据执行完成后，WebDriver已被完全关闭，后续的Scenario迭代无法再初始化新的浏览器实例，导致其余两组数据根本没有运行机会。此外，driver.close()关闭当前窗口后再调用driver.quit()属于重复操作，quit()本身就会关闭所有关联窗口并终止会话。

修复方案

使用Cucumber的@After钩子统一管理浏览器生命周期，确保每个Scenario（即每组测试数据）执行完成后再关闭浏览器，而不是在步骤方法中直接终止会话：

修改后的LoginDemoSteps.java：

import java.util.concurrent.TimeUnit;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;

import io.cucumber.java.After;
import io.cucumber.java.en.*;
import static org.junit.Assert.assertTrue;

public class LoginDemoSteps {
    
    WebDriver driver = null;
    
    @Given("browser is open")
    public void browser_is_open() {
        
        System.out.println("inside step - browser open");
        
        String projectPath = System.getProperty("user.dir");
        
        System.out.println(projectPath);
        
        System.setProperty("webdriver.chrome.driver",projectPath+"/src/test/resources/drivers/chromedriver.exe");
        
        driver = new ChromeDriver();
        
        driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
        driver.manage().timeouts().pageLoadTimeout(30, TimeUnit.SECONDS);

    }

    @And("user is on login page")
    public void user_is_on_login_page() {
        driver.navigate().to("https://practicetestautomation.com/practice-test-login/");
    }

    @When("^user enters (.*) and (.*)$")
    public void user_enters_username_and_password(String username, String password) throws InterruptedException {
        driver.findElement(By.id("username")).sendKeys(username);
        driver.findElement(By.id("password")).sendKeys(password);
        
        Thread.sleep(2000);

    }
    
    @And("user clicks on login")
    public void user_clicks_on_login() {
        driver.findElement(By.id("submit")).click();

    }

    @Then("user is navigated to the home page")
    public void user_is_navigated_to_the_home_page() throws InterruptedException {
        // 使用断言明确验证结果，失败时会抛出错误
        assertTrue("登录失败，未跳转到成功页面", driver.getPageSource().contains("Logged In Successfully"));
        System.out.println("Test Successful");
        Thread.sleep(2000);
    }

    // 添加After钩子，每个Scenario执行完成后关闭浏览器会话
    @After
    public void tearDown() {
        if (driver != null) {
            driver.quit();
        }
    }
}

额外优化建议

替换Thread.sleep()为Selenium的显式等待（WebDriverWait），避免固定等待时间导致的测试不稳定和效率低下。
始终使用断言验证测试结果，而非仅打印信息，这样测试失败时能直接定位问题。
