断言网页中缺少元素，给出NoSuchElementException [英] Assert Absence of element in the web page, giving NoSuchElementException

问题描述

需要声明网页中没有这样的元素，
尝试使用 fieldValueBox.isDisplayed（）; 而不是false时抛出 NoSuchElementFound异常。
现在我正在使用'try catch'并在'catch'中做出决定

Need to assert that there is no such element in the webpage, When tried with fieldValueBox.isDisplayed(); instead of "false" its throwing "NoSuchElementFound" exception. Right now i was using 'try catch' and making decision in 'catch'

推荐答案

如果元素不是在页面上，然后你会得到'NoSuchElementFound'异常。您可以尝试检查定位器的元素数量是否为零：

If the element is not on the page, then you will get 'NoSuchElementFound' exception. You can try checking that the number of elements with the locator is zero:

private boolean elementNotOnPage(){
    boolean elementIsNotOnPage = false;

    List<WebElement> element = driver.findElements(yourLocator);

    if(element.size() == 0){
        elementIsNotOnPage = true;
    }

    return elementIsNotOnPage;

}
