java - WebElementProxy 应该实现什么才能将其传递给 Actions.moveToElement(WebElement)？

问题描述

里面有org.openqa.selenium.interactions.Actions一个名为的方法moveToElement(WebElement target);

我有一个类WebElementProxy，它实现WebElement：

public class WebElementProxy implements WebElement {
    private WebElement el;
    public WebElementProxy(WebElement el) {
        this.el = el;
    }
    /* Implement methods from WebElement, delegating directly to el field. */
}

当我尝试打电话时，new Actions(driver).moveToElement(webElementProxy)我收到以下错误：

class mypackage$WebElementProxy cannot be cast to class org.openqa.selenium.interactions.Locatable

因此，我在 WebElementProxy 的接口中添加了 Locatable：

public class WebElementProxy implements WebElement, Locatable {
    private WebElement el;
    public WebElementProxy(WebElement el) {
        this.el = el;
    }
    /* Implement methods from WebElement and Locatable, delegating directly to el field. */
}

现在，当我打电话时，new Actions(driver).moveToElement(webElementProxy)我收到以下错误：

    at org.openqa.selenium.interactions.Actions.perform(Actions.java:595)
    at the place in my project where I called actions.movetoElement()

在这一点上，我不知道我还需要实现什么才能使这个方法调用正常工作。我在这里想念什么？

解决方案

在类似的情况下（使用 Serenity 的 WebElementFacade），它通过直接传递底层元素为我解决了：new Actions(driver).moveToElement(el).
