java - 使用 Selenium 和 Java 在 Facebook 中发布状态

Question

如何使用 Selenium 和 Java 在 Facebook 中发布状态？我尝试了下面的代码，但不起作用。能够登录，但发布状态时出现错误，没有此类元素。登录后，我收到通知弹出窗口允许或阻止，如何也处理这个弹出窗口？下面是我用于测试的代码。

public class NewTest {
private WebDriver driver;

 @Test
public void testEasy() throws InterruptedException {

driver.get("https://www.facebook.com/");
Thread.sleep(5000);
driver.findElement(By.id("email")).sendKeys("email");
driver.findElement(By.id("pass")).sendKeys("password" + Keys.ENTER);

Thread.sleep(5000);

driver.findElement(By.xpath("//textarea[@title=\"What's on your mind?\"]")).click();
driver.findElement(By.xpath("//textarea[@title=\"What's on your mind?\"]")).sendKeys("Hello World");
driver.findElement(By.xpath("//textarea[@title=\"What's on your mind?\"]")).sendKeys(Keys.ENTER);

}

@BeforeTest
public void beforeTest() {
System.setProperty("webdriver.chrome.driver",
    "C:\\Users\\admin\\Desktop\\Test\\chromedriver_win32\\chromedriver.exe");
driver = new ChromeDriver();
}

@AfterTest
public void afterTest() {
driver.quit();
}

}

Answer 1

1. 据我所知，您的 XPath 表达式不太正确 title相关textarea看起来像:

   What's on your mind, user1984
   

   因此您需要修改定位器以使用 XPath contains() function像:

   By.xpath("//textarea[contains(@title,\"What's on your mind\")]")
   

2. 使用Thread.sleep是 performance anti-pattern ，您应该使用 WebDriverWait反而。重构代码示例:

   driver.get("https://www.facebook.com/");
   WebDriverWait wait = new WebDriverWait(driver, 5);
   wait.until(ExpectedConditions.elementToBeClickable(By.id("email"))).sendKeys("email");
   wait.until(ExpectedConditions.elementToBeClickable(By.id("pass"))).sendKeys("password" + Keys.ENTER);
   
   
   wait.until(ExpectedConditions.elementToBeClickable(By.xpath("//textarea[contains(@title,\"What's on your mind\")]"))).click();
   wait.until(ExpectedConditions.elementToBeClickable(By.xpath("//textarea[contains(@title,\"What's on your mind\")]"))).sendKeys("Hello World");
