问题描述
如果我的问题听起来很重要，我提前道歉，我在QA和Selenium非常新。
My apologies in advance if my question sounds primary, I am very new at QA and Selenium.
之间的确切区别是：
wait.until(ExpectedConditions.visibilityOfElementLocated
(By.xpath("//a[text()='Show advanced settings...']"))).click();
和
wait.until(ExpectedConditions.presenceOfElementLocated
(By.xpath("//a[text()='Show advanced settings...']"))).click();
我看了但是没弄明白。
推荐答案
visibilityOfElmementLocated检查元素是否存在且是否可见。要检查可见性，请确保元素的高度和宽度大于0.
The visibilityOfElmementLocated checks to see if the element is present and also visible. To check visibility it makes sure the element has a height and width greater than 0.
presenceOfElementLocated只检查dom以查看它是否可以定位元素，无论其可见性如何。
The presenceOfElementLocated just checks the dom to see if it can locate an element no matter its visibility.
