WebDriver拾级而上·之十九 常用方法

一、判断元素是否存在

 public static boolean isElementPresent(WebDriver driver, By by) {
        try {
            driver.findElement(by);
            return true;
        } catch (NoSuchElementException e) {
            return false;
        }
  }

二、判断Alert是否存在

public static boolean isAlertPresent(WebDriver driver) {
        try {
            driver.switchTo().alert();
            return true;
        } catch (NoAlertPresentException e) {
            return false;
        }
 }

三、获取弹框的文本

acceptNextAlert弹框的操作类型，true点击确认操作，false点击取消操作

 public static String closeAlertAndGetItsText(WebDriver driver,boolean acceptNextAlert) {
        try {
            Alert alert = driver.switchTo().alert();
            String alertText = alert.getText();
            if (acceptNextAlert) {
                alert.accept();
            } else {
                alert.dismiss();
            }
            return alertText;
        } finally {
            acceptNextAlert = true;
        }
 }
