Question

我一直在尝试使用Java进行Appium测试设置以在Android上进行测试。为了验证我的元素，我一直在使用AndroidUiAutomator。在UI Automator Viewer中，我可以看到已传播辅助功能标签（请参阅附图）。当我使用findElement（By.name | By.AccessibilityId | etc时，它通常只会超时，并且必须重新启动Appium服务器终端控制台才能运行测试。我使用FindByXPath获得类似的结果。我尝试使用超时和等待驱动程序等待确保元素已加载，但无济于事。我已经尝试了下面代码中列出的所有内容。

Answer 1

您未使用default timeout，因此如果定位符正确，appium服务器可以花时间搜索元素。您应该使用显式等待来正确加载元素。

在功能中添加超时。

capabilities.setCapability("newCommandTimeout", 50);

如果element是，则根据元素类型使用这些显式等待函数 clickable try等待clickable，如果元素不是clickable，请尝试仅包含元素的可见性

WebDriverWait wait = new WebDriverWait(driver, 30);

public void waitForMobileElementVisible(MobileElement element)
    {
           wait.until(ExpectedConditions.visibilityOf(element));

     }



    public void waitForMobileElementClickable(By by)
    {
            wait.until(ExpectedConditions.elementToBeClickable(by));
     }

Answer 2

要在Android上使用按内容说明查找，您必须使用以下内容：

public WebElement getByContentDescription(String string){
    return driver.findElement(By.ByXPath("//*[@content-desc='"+string+"']");
}

Answer 3

import pandas as pd
import numpy as np

df = pd.DataFrame({
        'Time' : ['09:00:00.1','09:00:00.1','09:00:00.1','09:00:00.1','09:00:00.1','09:00:00.2','09:00:00.2','09:00:00.2','09:00:00.2','09:00:00.2'],                 
        'Label' : ['A','B','C','D','E','A','B','C','D','E'],                 
        'X' : [8,4,3,8,7,7,3,3,4,6],
        'Y' : [3,3,3,4,3,2,1,2,4,2],
        })

# make the radii explicit
df.loc[:, 'norm2'] = np.linalg.norm(df.loc[:, ['X', 'Y']].values, axis=1)
# 517 µs ± 4.68 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)

# with radii appended
In [1]: df
Out[1]:
         Time Label  X  Y     norm2
0  09:00:00.1     A  8  3  8.544004

# indexing the DataFrame before counting with `groupby`

In [2]: df[df['norm2'] < 4].groupby(['Time', 'Label'])['norm2'].count()
Out[2]:
Time        Label
09:00:00.2  B        1
            C        1
Name: norm2, dtype: int64

我建议使用Appium的Java客户端提供的注释来通过内容描述查找元素。有一些好处：

1）速度-在需要它以减少点击前的时间之前进行查找

2）自定义-无需与iOS保持一致，因为您可以在其他注释的顶部使用@iOSXCUITFindBy（id =“ Accessibility ID”）

3）懒惰地查找元素-仅在需要时才查找元素！

Appium无法通过content-description / accessibilityID找到元素
