如何使用Selenium验证页面标题？附登录场景测试代码示例

Here's a polished, working solution using Selenium and TestNG to verify your homepage title after successful login, building directly on your provided code snippets:

Full Code Implementation #

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.testng.Assert;
import org.testng.annotations.AfterMethod;
import org.testng.annotations.BeforeMethod;
import org.testng.annotations.Test;

public class LoginTitleVerificationTest {
    private WebDriver driver;
    // Replace with your actual application base URL
    private String baseUrl = "https://your-application-url.com";

    @BeforeMethod
    public void setUp() {
        // Initialize ChromeDriver (ensure ChromeDriver is in your system path or specify its location)
        driver = new ChromeDriver();
        driver.manage().window().maximize();
    }

    @Test(priority = 0)
    public void performLogin() throws Exception {
        driver.get(baseUrl + "/");
        
        // Enter email and password
        driver.findElement(By.name("email")).clear();
        driver.findElement(By.name("email")).sendKeys("lanka@ensiz.com");
        
        driver.findElement(By.name("password")).clear();
        driver.findElement(By.name("password")).sendKeys("123456");
        
        // Click Sign In button
        driver.findElement(By.xpath("//button[contains(text(),'Sign In')]")).click();
        
        // Optional: Use explicit wait instead of sleep for better reliability
        // WebDriverWait wait = new WebDriverWait(driver, Duration.ofSeconds(10));
        // wait.until(ExpectedConditions.titleContains("Placer Admin"));
    }

    @Test(priority = 1, dependsOnMethods = "performLogin")
    public void verifyHomepageTitle() {
        String expectedTitle = "Placer Admin - Home";
        String actualTitle = driver.getTitle();
        
        // Assert that the actual title matches the expected value
        Assert.assertEquals(actualTitle, expectedTitle, 
            String.format("Homepage title mismatch: Expected '%s', got '%s'", expectedTitle, actualTitle));
    }

    @AfterMethod
    public void tearDown() {
        // Clean up resources after each test
        if (driver != null) {
            driver.quit();
        }
    }
}

Key Details & Best Practices #

• Test Dependencies: Using dependsOnMethods = "performLogin" ensures the title verification only runs if the login is successful, which is more robust than relying solely on priority.
• Assertions: The Assert.assertEquals method provides a clear error message if the title doesn't match, making debugging easier.
• Explicit Waits: Instead of hardcoding Thread.sleep, use explicit waits (commented in the code) to wait for the title to update or elements to load. This makes your tests more stable and less flaky.
• Resource Management: The @AfterMethod annotation ensures the browser is closed after each test, preventing resource leaks.
