Instrumentation Framework-based open source project AndroidMonkey is how, many novices are not very clear about this, in order to help you solve this problem, the following editor will explain in detail for you, people with this need can come to learn, I hope you can gain something.

One of the biggest questions is how monkey uses instrumentation to inject event. In that case, how can it send events across process applications? Because according to my understanding of the instrumentation framework can not cross-process, and monkey is absolutely cross-process!

@ Override public int fireEvent (Instrumentation testRuner) {String note; if (mAction = = KeyEvent.ACTION_UP) {note = "ACTION_UP";} else {note = "ACTION_DOWN" } System.out.println (": Typing Key (" + note + "):" + mKeyCode + "/ /"); try {/ / testRuner.sendKeySync (getEvent ()); testRuner.sendKeyDownUpSync (mKeyCode) } catch (Exception e) {System.out.println ("Failed to send key (" + note + "):" + mKeyCode + "/ /"); return MonkeyEvent.INJECT_FAIL;} return MonkeyEvent.INJECT_SUCCESS;}

After struggling for a period of time, I went back to the download place to take a look at the overview, which is very short, but clearly describes that this is not the monkey I want, but a modified android library of native monkey. Since we have encountered it, let's translate its introduction and use. Anyway, there are only a few words, and we will further study it in the future. As to whether it really cannot cross the process as I said, it will be left to the future or everyone to verify it.

1. Overview

AndroidMonkey is an android library. In fact, it is a test library based on native monkey to facilitate testing and analysis (for example, code coverage).

Testers / users can easily use this library to create random test scripts for Android gui applications

Why this library:

Why use this library:

With this library, you can write random test cases for your app in just a few lines of code.

You can add assertions to your test code to easily determine the current situation of your SUT (system / application under test) (it is difficult to do so if you use monkey).

You can do a coverage analysis of your app through a random test, which is very useful for our research (like what I'm doing now). (translator's note: in fact, this last sentence should be understood like this: if you are a company buyer, and you want to evaluate whether an application is stable enough to meet your needs, then you will try it and do some preliminary research first.)

Code example/ code example public class ContactAdderTest extends ActivityInstrumentationTestCase2 {private int NUM_EVENTS = 1000; public ContactAdderTest () {super ("com.example.android.contactmanager", ContactAdder.class);} @ Override protected void setUp () throws Exception {super.setUp (); setActivityInitialTouchMode (false) } public void testMonkeyEvents () {Display display = getActivity (). GetWindowManager (). GetDefaultDisplay (); Instrumentation inst = getInstrumentation (); PackageManager pm = getActivity (). GetPackageManager (); Monkey monkey = new Monkey (display, "com.example.android.contactmanager", inst, pm) / / Generate and fire a random event. For (int I = 0; I < NUM_EVENTS; iTunes +) {monkey.nextRandomEvent ();}

two。 Introduction to use

Introduction to use

Brief introduction

Here is how to use this library:

Details

C create an android project

First create an Android Test Project project and add a reference to the AndroidMonkey library (reference jar or project) through Android ADT [http://developer.android.com/sdk/eclipse-adt.html]]

Create a test class

Create a normal ActivityInstrumentationTestCase2 test class, and then add the following test case code:

Public void testMonkeyEvents () {Display display = getActivity (). GetWindowManager (). GetDefaultDisplay (); Instrumentation inst = getInstrumentation (); PackageManager pm = getActivity (). GetPackageManager (); Monkey monkey = new Monkey (display, packageToTest, inst, pm); for (int I = 0; I < NUM_EVENTS; iTunes +) {monkey.nextRandomEvent ();}} will it help you to read the above content?
