如何使用selenium.WebDriver和HtmlUnitDriver注销的Facebook

Question

我使用selenium.WebDriver和HtmlUnitDriver登录到Facebook上，但我不能注销。

public static void main(String[] args) throws InterruptedException {

WebDriver driver = new HtmlUnitDriver();
driver.get("http://www.facebook.com");
System.out.println("Title of the page "+ driver.getTitle());
WebElement username = driver.findElement(By.id("email"));
username.sendKeys("[email protected]"); 
WebElement password = driver.findElement(By.id("pass"));
password.sendKeys("xxxxx");
WebElement Signup_button = driver.findElement(By.id("loginbutton"));
Signup_button.click();
Thread.sleep(5000);
System.out.println("After login title is = " + driver.getTitle());

到现在为止它的工作原理。和下面的步骤覆盖注销部分（不工作）：

WebElement logOut = driver.findElement(By.id("userNavigationLabel"));
logOut.click();
Thread.sleep(5000);
WebElement signOut = driver.findElement(By.name("Log Out"));
logOut.click();

System.out.println("Logged Out Successfully!!!!!!!!!!!!!!!!!!!");
String pagetitle = driver.getTitle();
System.out.println(pagetitle);

}}

错误：

Exception in thread "main" org.openqa.selenium.NoSuchElementException: Unable to locate element with name: Log Out

Facebook的注销HTML代码

<span><span class="_54nh"><form class="_w0d"
 action="https://www.facebook.com/logout.php" data-nocookies="1" 
id="show_me_how_logout_1" method="post" onsubmit="return window.Event
 &amp;&amp; Event.__inlineSubmit &amp;&amp; 
Event.__inlineSubmit(this,event)"><input name="fb_dtsg" 
value="AQGzvtPjFD1W:AQFslBEMcQG9" autocomplete="off" type="hidden"><input
 autocomplete="off" name="ref" value="mb" type="hidden"><input 
autocomplete="off" name="h" value="AfeziZXPRhN6ncxD" type="hidden">
</form>Log Out</span></span>

我也通过SAURABH野牛Selenium WebDriver Log Out from Facebook尝试这个代码

WebDriverWait wait = new WebDriverWait(driver, 10);
WebElement accountSettings = wait.until(ExpectedConditions.elementToBeClickable(By.linkText("Account Settings")));
accountSettings.click() //this will click on setting link to open menu
WebElement logOut = wait.until(ExpectedConditions.elementToBeClickable(By.linkText("Log Out")));
logOut.click() // this will click on logout link

错误

有一个在名称（定位）没有属性，请使用其他属性（定位）为ID =“show_me_how_logout_1”或任何其他定位。

试试下面的代码。
