java-appium-527进阶-1 UiAutomator1&2区别和封装

1.UiAutomator和UiAtumator2的区别:

1.1 UiAutomator1有关于id定位的策略

** UiAutomator1 id定位在resourceid匹配失败时,会匹配contentDesc。 **
安卓会根据id进行3种情况的判断:

  • 1.resourceId 如user_profile_icon
  • 2.accessibility id
  • 3.Strings.xml 研发所写的resource id,包含包名,如com.xueqiu.android:id/user_profile_icon。如果传入的text是resource Id将只使用resource id选择器
更多信息在appium/appium-android-bootstrap分支,详见https://github.com/appium-boneyard/appium-android-bootstrap/blob/master/bootstrap/src/io/appium/android/bootstrap/handler/Find.java。

1.2 UiAutomator2定位策略

UiAutomator2中id定位只匹配resourceId

if (by instanceof ById) {
            String locator = rewriteIdLocator((ById) by);
            return CustomUiDevice.getInstance().findObject(android.support.test.uiautomator.By.res(locator));
        } else if (by instanceof By.ByAccessibilityId) {
            return CustomUiDevice.getInstance().findObject(android.support.test.uiautomator.By.desc(by.getElementLocator()));
        } else if (by instanceof ByClass) {
            return CustomUiDevice.getInstance().findObject(android.support.test.uiautomator.By.clazz(by.getElementLocator()));
        } else if (by instanceof By.ByXPath) {
            final NodeInfoList matchedNodes = getXPathNodeMatch(by.getElementLocator(), null);
            if (matchedNodes.size() == 0) {
                throw new ElementNotFoundException();
            }
            return CustomUiDevice.getInstance().findObject(matchedNodes);
        } else if (by instanceof By.ByAndroidUiAutomator) {
            UiSelector selector = toSelector(by.getElementLocator());
            if (selector == null) {
                throw new UiSelectorSyntaxException(by.getElementLocator(), "");
            }
            return CustomUiDevice.getInstance().findObject(selector);
}

2. 查找控件方法的简单封装

在UiAutomator1中,id定位会去匹配contentDesc,此处只考虑xpath, id, contentDesc。
传入String,辅以正则表达式,如果匹配Xpath,就用xpath定位;如果匹配id,就用id定位

    public WebElement locate(String locate){
        if (locate.matches("\\/\\/.*")){
            return  driver.findElementByXPath(locate);
        }else{
            return driver.findElementById(locate);
        }
    }

3. id和xpath定位的区别

使用id,contentDesc,class定位都是使用uiatumator自带的方法,使用xpath定位需要先获取节点信息,再对节点信息做检索 同一个元素:id: "com.xueqiu.android:id/tv_login" xpath: //*[@resource-id,"com.xueqiu.android:id/tv_login" ] ```#shell # 使用该命令可以查看执行时间,v代表详细信息,此处只查看结果和执行时间,将--v去除 time curl -X POST http://127.0.0.1:4723/wd/hub/session/${SessionId}/elements --data-binary '{"using":"id","value":"com.xueqiu.android:id/tv_login"}' -H "Content-Type: application/json; charset=UTF-8" --v

# 4.总结

<font color=#458B00>    1.UiAutomator使用id在匹配resourceId失败时,会使用ACCESSIBILITY_ID定位
     UiAtumator2使用id定位被限制,只能使用resourceId定位
    2.使用xpath和id定位,耗时差别可接受</font>
