注释"@FindBy"的用途是什么?

问题描述

有人可以向我解释WebDriver中的注释@FindBy吗?

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Page Factory支持页面对象时，它可以协助定位器的构建

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

PageFactory Wiki页面

但是，我发现将定位符存储为By对象而不是WebElement更为有用，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;

这样，您可以在断言元素不存在时使用定位器，或者在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.
