我应该使用哪种方法(最快)来选择元素? [英] Which method should I use (fastest) to select element?
问题描述
嗯，有很多不同的方法可以在驱动程序之间选择元素.我想知道哪个最快，最适合原生应用(iOS和Android).
Well there are a lot of different methods to select elements between Drivers. I would like to know which one is the fastest and the most suitable for native apps (iOS and Android) .
Appium Driver 类有:
With the Appium Driver class there is :
findElementByAccessibilityId(String using)
移动类有:
findElement(org.openqa.selenium.By by) //with ById/Xpath/Name/ClassName...
Android 和 iOS 驱动程序类有:
With Android and iOS driver class there are :
findElementByAndroidUIAutomator(String using)
findElementByIosUIAutomation(String using)
使用 RemoteWebDriver 类有:
And using the RemoteWebDriver class there are :
findElementById();
findElementByXPath();
findElementById(); //css, className etc... -> WebElement which can be cast in mobileElement
所以我猜使用 UIAutomator 和 UIAutomation 会更快，但是 Android 2.3+ 需要 selendroid.
So I'm guessing using UIAutomator and UIAutomation are faster but selendroid is needed for Android 2.3+.
你是怎么做的，为什么?你能给我提供一些 findElementByAndroidUIAutomator(String using) 和 findElementByIosUIAutomation(String using)
How do you do and why? Can you provide me some examples for findElementByAndroidUIAutomator(String using) and findElementByIosUIAutomation(String using)
我发现 XPath 选择器存在一些问题.从我的角度来看，使用 findElement(By.name) 似乎很简单.
I saw there are some issues with XPath selectors. From my point of view using findElement(By.name) seems quite simple.
推荐答案
好吧，只要可以，就使用 UiAutomator、UiAutomation(默认情况下，客户端库会这样做 - 对于 Id/Name 等...-，除了 XPath，它速度较慢，请在没有选择的情况下使用它.
Well , just use UiAutomator, UiAutomation when you can (by default client-libs do it -for Id/Name etc...-, except for XPath which is slower, so use it when you haven't the choice.
见https://github.com/appium/java-client/issues/158
我使用了一个函数，它接受字符串选择器的参数和每个类型的自定义枚举(id、xpath，甚至自定义类型，如 Android parentIdChildEditText-仍然使用 UiAutomator- 等...) -> 不要这样做！
经过多年的经验，如果可以，请使用 AccessibilityId:其中
After years of experience, just use AccessibilityId if you can : which
- 对于 ios 是 name 在您的 appium xml 源中 名称您的 ios 开发人员的辅助功能标识符
- 对于 android 是 contentDesc <=> 相同的 appium 源/开发标识符
- for ios is name in your appium xml source <=> accessibilityIdentifier for your ios dev
- for android is contentDesc <=> same appium source/dev identifier
否则，最简单的 选择器适合您(即使是带有文本的 xpath，但最好使用自定义测试 ID).对于这些类型的测试，选择器性能是最后一个问题，维护和健壮性是重点.
Otherwise, the simplest selector for you (even xpath with text, still better to have custom test-id though). For these type of tests, selector performance is your last problem, maintenance and robustness are the main points.
