问题描述

谁能解释一下WebDriver 中的注释@FindBy?

Can anyone explain me about Annotation @FindBy in WebDriver?

在哪里以及为什么使用它?

Where and why it is used?

推荐答案

当使用页面工厂来支持你的页面对象时，帮助构建定位器

It's to assist with the construction of locators when using the Page Factory to support your Page Objects

PageFactory 维基页面

但是我发现我发现将定位器存储为 By 对象而不是 WebElements 更有用，因为它们更灵活，并且您倾向于避免遇到 StaleElementException.

However I'm discovering that I find it more useful to store your locators as By objects rather than WebElements as they are more flexible and you tend to avoid running into the StaleElementException.

By myLocator = By.id("idOfYourElement")

代替

@FindBy(id = "idOfYourElement")
WebElement myLocator;

通过这种方式，您还可以在断言元素不存在时使用定位器或在 ExpectedConditions 帮助器中使用它.

This way you can also use your locators when asserting the absence of an element or use it in the ExpectedConditions helpers.
