UiAutomator2.0 - 獲取同行控件

目錄

問題：UI測試時，在同一個界面出現相同的屬性的控件(如圖)，對於這種控件的獲取非常無奈。若是直接經過控件id去查找的話老是會返回界面該類型的第一個控件。

解決：
1.UiObject2 中已經給出瞭解決方法，能夠經過 getParent()方法處理。缺點：因爲UiObjec2t控件與視圖進行綁定，當視圖變化後該控件對象就被銷燬了。因此屢次使用則很是不便利

@Test
public void testCase_Btn(){
       UiObject2 switchBtn = device.findObject(By.text("Automatic 24‑hour format"))
               .getParent().getParent().findObject(By.res("android:id/switch_widget"));
       if(switchBtn.isChecked()){
           switchBtn.click();
       }
       assertTrue("switch btn is open", !switchBtn.isChecked());
}

2.UiObject中經過id + instance 去能查找到控件，可是界面變更的話腳本也得變更，可靠性不強。只能採起折中的方式來獲取了。很少說，直接上代碼。

UiObject switchBnt3 = device.findObject(new UiSelector().resourceId("android:id/switch_widget").instance(2));

測試類：

@Test
public void testCase_Btn() throws UiObjectNotFoundException {
       UiObject timeFormat = device.findObject(new UiSelector().text("Automatic 24‑hour format"));
       UiObject switchBtn = ControlObj.getUiObject(timeFormat);
       if(switchBtn.isChecked()){
           switchBtn.click();
       }
       assertTrue("switch btn is open", !switchBtn.isChecked());
}
