Selenium：启动网站后我们如何检查是否启动了正确的页面

在 Selenium 中：启动网站后，我们如何检查是否启动了正确的页面。

例子： 如果我想启动www.google.com，运行代码后如何检查是否已启动同一页面。

I used,

Assert.assertEquals("Correct web page",driver.findElement(By.Xpath("<xpath of one of the element in the page>")).isDisplayed ());

运行程序后，我收到以下错误：

Exception in thread "main" java.lang.AssertionError: expected:<Correct web page> but was:<true>

有很多方法可以断言页面是否正确加载，最常用的是断言正确加载的 url 和页面标题。

断言已加载正确的 URL：

String expectedUrl = "https://www.google.com";
WebDriver driver = new FirefoxDriver();
driver.get(expectedUrl);
try{
  Assert.assertEquals(expectedUrl, driver.getCurrentUrl());
  System.out.println("Navigated to correct webpage");
}
catch(Throwable pageNavigationError){
  System.out.println("Didn't navigate to correct webpage");
}

断言页面标题：

String expectedTitle = "Google";
String expectedUrl = "https://www.google.com";
WebDriver driver = new FirefoxDriver();
driver.get(expectedUrl);
try{
  Assert.assertEquals(expectedTitle, driver.getTitle());
  System.out.println("Navigated to correct webpage");
}
catch(Throwable pageNavigationError){
  System.out.println("Didn't navigate to correct webpage");
}
