使用“ @AndroidFindBy（）”定位元素时获取“ NoSuchElementException”

时间：2019-05-08 06:28:09

标签： java selenium appium-android

设置为： Android模拟器版本：Nexus 5X API 27，Android 8.1（Google Play）和浏览器：Google Chrome

我的声明如下：

    @AndroidFindBy(id = "user_login")
    WebElement user_login;

    @AndroidFindBy(id = "user_pass")
    WebElement user_pass;

    @AndroidFindBy(id = "wp-submit")
    WebElement wp_submit;

    String url = "http://demosite.center/wordpress/wp-login.php";

HTML：

<input type="submit" name="wp-submit" id="wp-submit" class="button button-primary button-large" value="Log In">

使用WebElements的方法

    public void enter(String usr, String pwd) {
        try {
            user_login.sendKeys(usr);
            System.out.println("entered username");
            Thread.sleep(2000);

            user_pass.sendKeys(pwd);
            System.out.println("entered password");
            Thread.sleep(2000);

            wp_submit.click();
            System.out.println("clicked login button");
            Thread.sleep(2000);
        } catch (Exception e) {
            e.printStackTrace();
        }

我得到的例外是：

我的假设：该脚本使用WebElement的变量名在UI上定位该元素，而不是我在@AndroidFindBy中传递的定位器。

请告知我是否需要我提供更多信息。

编辑1：

@AndroidFindBy(id = "user_login")
WebElement userName;

以上操作无效 

@AndroidFindBy(id = "user_login")
WebElement user_login;

将变量名更改为id的名称后，上面的代码就可以正常工作

在此处发布问题之前，我已经在google上引用了以下引用，但是它们对@AndroidFindBy的实现略有不同，或者没有使用此方法。

按照https://docs.microsoft.com/en-us/previous-versions/azure/ad/graph/api/entity-and-complex-type-reference#approleassignment-entity

  

用于标记页面对象上的字段，以指示用于定位元素或元素列表的替代机制。与PageFactory结合使用，可以使用户快速轻松地创建PageObjects。 使用Android UI选择器，可访问性，ID，名称，类名称，标记和xpath

这意味着您可以使用此注释来访问 Android UI元素，例如浏览器的“后退”和“重新加载”按钮

鉴于您要在Chrome浏览器中自动化网页，应将所有出现的@AndroidFindBy替换为@AndroidFindBy annotation documentation
