Android automated testing (2) Search for objects by ID (java)

Android automated testing (2) Search for objects by ID (java)

In the previous article, I wrote about Android automated testing (1) how to install and uninstall an application (java). Next I will explore how to find objects by ID in common java applications.

1. Class Library dependency:

The library dependencies are:
Chimpchat. jar, common. jar, ddmlib. jar, guava-13.0.1.jar, sdklib. jar, hierchyviewer2lib. jar
They can all be found in the sdk/tools/lib subdirectory of the ADT bundle.

2. Code:

package com.robot.dream.test;import com.android.chimpchat.adb.AdbBackend;import com.android.chimpchat.adb.LinearInterpolator.Point;import com.android.chimpchat.core.IChimpDevice;import com.android.chimpchat.core.TouchPressType;import com.android.chimpchat.hierarchyviewer.HierarchyViewer;import com.android.hierarchyviewerlib.models.ViewNode;public class TestRobotDream {    public static Point getAbsoluteCenterOfView(ViewNode node) {        Point point = getAbsolutePositionOfView(node);        return new Point(point.getX() + node.width / 2, point.getY() + node.height / 2);    }    public static Point getAbsolutePositionOfView(ViewNode node) {        int x = node.left;        int y = node.top;        for(ViewNode p = node.parent; p != null; p = p.parent) {            x += p.left - p.scrollX;            y += p.top - p.scrollY;        }        return new Point(x, y);    }    /**     * @param args     */    public static void main(String[] args) {        System.out.println("start");        IChimpDevice device = new AdbBackend().waitForConnection();        System.out.println("device ok");                device.shell("am start com.robot.dream/com.robot.dream.MainActivity");        System.out.println("monkey test connected");        HierarchyViewer view = device.getHierarchyViewer();        ViewNode viewNode = view.findViewById("id/center_image");        //Point p = HierarchyViewer.getAbsoluteCenterOfView(viewNode);        Point p = getAbsoluteCenterOfView(viewNode);        //EasyMonkeyDevice easyDevice = new EasyMonkeyDevice(null);        System.out.println(" x: "+p.getX() + " y: "+p.getY());        //By.id("");        //By selector = By.id("");        System.out.println("touch 1 ok");        device.touch(p.getX(), p.getY(), TouchPressType.DOWN_AND_UP);        System.out.println("touch 2 ok");        device.touch(p.getX(), p.getY(), TouchPressType.DOWN_AND_UP);        //easyDevice.touch(selector, TouchPressType.DOWN_AND_UP);        device.dispose();    }}

3. limitations:

The preceding automated testing is implemented using java and lib corresponding to monkeyrunner.

Therefore, it is essentially the java version of monkey runner.

It can basically implement the functions that can be implemented by the monkey runner. If java is used for implementation, there are fewer documents and less materials, which is not worth the candle.

To explore how to implement it using java, the greatest achievement is the learning of these test-related classes.

4. We will introduce Android monkeyrunner & Android Unit Test & Android Code Coverage Test later.
