Android :: Good Automated Unit And System Test Tools?
Nov 3, 2010
I approached this problem as an oh hey that's not too bad, I can write a bunch of unit tests, and I have been keeping my suite green. However as things get more involved continuous integration and testing is a great great thing to have. And then I saw oh Android has emma integration as well awesome ... and then that's where it get's iffy. So I setup Hudson and have it call the coverage target of the ant build.xml that the android executable in the sdk can generate. And then it hits me. adb -s <emulator> shell am instrument -w ... will never return a result code that is not 0 ... because adb technically exited cleanly and usually will regardless of how the shell command that executed did..............

I'm writing an Android JUnit test and want to copy/reset a test fixture file (it's an SQLite database file.) If I were within the main application, I know I could just place the file in the assets directory and use getResources().getAssets().open(sourceFile).However, this API appears to be unavailable from the ActivityInstrumentationTestCase2 class.Is there an easy way to copy a file over from the testing PC, or should I just keep a fresh copy of a test fixture on the device and copy it over a temporary file?

I am using ActivityInstrumentationTestCase2 to do some test for an activity. I get a button in the setUp() method like this: protected void setUp() throws Exception {super.setUp(); act = getActivity(); btn = Button)act.find ViewById ( R.id.bike_button ); // this button has been defined in layout} Then I use this button to perform a click in a test method like this: public void testBikeButton(){ //click the bike button btn.performClick();}

I'm working on a school project and I'm researching testing possibilities for Android applications. On this page: http: // developer . android . com/ resources / tutorials /testing /hello android. Google writes about a unit test. Is this really a unit test? A Unit test will not integrate all classes and will not test in his context. So my opinion is it is not a Unit Test but an Integration Test.

Sorry if this is a bit of a vague question, however im struggling to find a single solid example on how to do unit testing (isolated testing) with Android. So one project contains models and logic, then another project contains tests for said library. There is no front end or UI, so I want to do the bare minimum to just be able to test that my methods all work in isolation.

I just switched the way my Android project is being built and non of my unit tests work any more...I get errors like WARN/dalvikvm(575): VFY: unable to resolve static field X in WARN/dalvikvm(575): VFY: unable to find class referenced in signature These errors only come from my Unit Tests, where classes defined in it can't even see other classes defined in the unit test. Before each project had it's own directory with copies of the 3rd party jar files. I've read around that Dex does weird things with references but haven't been able to figure out how to fix this problem. Is there a better way to do this? I would love to see an example of a large Android workspace where there are multiple projects, jar references, etc.Is it possible to fix this with an Order/Export tweak ?

I my main app and tests are organized like this (standard from "android create project"): AndroidManifest.xml assets/ main app asset files src/tests/AndroidManifest.xml -- uses <instrumentation> to point to the main app assets/ -- test-specific asset files src/ Writing test cases with AndroidTestCase, I'd like to load asset files from the test-specific assets/ directory, not from the main app assets/ directory. How can I accomplish that? The normal way to load an asset would be getContext().getAssets().open ("foo.txt"), for assets/foo.txt in the main app. I assume I just have to somehow change the Context or the AssetManager to point to the test- specific assets directory, but I don't see any way to do that. I have looked into the tests/bin/MyApp-debug.apk to confirm that the test assets are in there. Now I just need a way to access them.

I am trying to unit test a class that does SAX parsing and creates an object.This class takes a string as a parameter representing the URL of a document on the internet, parses it and then creates an object based on the contents.I don't want to have the unit tests actually access the network, so I'd like to have a few test xml files to parse. However I can't figure out how to access them from my AndroidTestCases. I don't want to include the test files with the actual application, I want them in the test project (it's a separate project, as is the norm for Android tests from what I could gather - due to the need to have a custom AndroidManifest.xml, for one).One way would be to put the XML files in the test project's assets directory, I can read them using getContext() .getAssets().open(filename) into an InputStream in the test case, but my class expects a URL string. I'd rather not have to provide an InputStream to this class instead of the current URL string. I can test just the parsing by making two methods, one that takes a string and one an Inputstream, and test the second, but how can I then test the one that just takes a string?How should I design my class and or tests to circumvent this problem?

Being able to write Android apps in regular Java is a huge win. However, I am confused about unit testing Android apps. Many of the 'best practices' seem to boil down to 'split your business logic off, and test it separately using JUnit'. This is great as far as it goes. And I understand that truly testing the UI will require firing up the emulator. But it seems there is a category of UI tests that I should be able to run without the emulator. The various Mockxxx classes seem to be going a long way towards this. But why (oh why oh why!) do they all. throw new RuntimeException( "Stub!" ); in their constructors? I can understand them doing this in their METHODS (then I could subclass them as needed) but why their constructors? I cannot stop this functionality so I cannot do (limited but useful) UI tests such as public TextView createTextView ( Context context ) {return new TextView( context );

i'm trying to write an unit test for my Android's RelativeLayout. Currently, my testcode setup is as follow:public class SampleRelativeLayoutTest extends AndroidTestCase {private ViewGroup testView;private ImageView icon;private TextView title;@Overrideprotected void setUp() throws Exception {super.setUp();
// inflate the layout
final Context context = getContext();
final LayoutInflater inflater = LayoutInflater.from(context);
testView = (ViewGroup) inflater.inflate(R.layout.sample_layout,
null);
// manually measure and layout
testView.measure(500, 500);
testView.layout(0, 0, 500, 500);
// init variables
icon = (ImageView) testView.findViewById(R.id.icon);
title = (TextView) testView.findViewById(R.id.title);
}However, I encountered NullPointerException with the following stack tracejava.lang.NullPointerException
at android.widget.RelativeLayout.onMeasure(RelativeLayout.java:427)
at android.view.View.measure(View.java:7964)
at com.dqminh.test.view.SampleRelativeLayoutTest.setUp(SampleRelativeLayoutTest.java:33)

at android.test.InstrumentationTestRunner.onStart(InstrumentationTestRunner.java:430)
at android.app.Instrumentation$InstrumentationThread.run(Instrumentation.java:1447)
What should I change in my setUp() code to make the test run properly ?

I am starting with an Activity based off of this ShakeActivity and I want to write some unit tests for it. I have written some small unit tests for Android activities before but I'm not sure where to start here. I want to feed the accelerometer some different values and test how the activity responds to it. For now I'm keeping it simple and just updating a private int counter variable and a TextView when a "shake" event happens. So my question largely boils down to this: How can I send fake data to the accelerometer from a unit test?

I'm writing unit tests for a ListActivity in Android that uses a handler to update a ListAdapter. While my activity works in the Android emulator, running the same code in a unit test doesn't update my adapter: calls to sendEmptyMessage do not call handleMessage in my activity's Handler. How do I get my ActivityUnitTestCase to sync with the MessageQueue thread and call my Handler?

I can run the unit test cases either by :
1. command line ' adb shell am instrument -w com.example.android.apis.tests/android.test.InstrumentationTestRunner'
2. Go to 'Dev' and clicks 'Instrumentation' and click 'Test API Demo'.But my questions now is, how can I debug my unit test cases? I try 'Debug' my APIDemoTest eclipse project and then do #2 above, it did not break at any of my breakpoints I setup.

I want to test parsing of data returned from server.I thought I might create several test XML files and then feed them to the sax parser which uses my custom data handler (as in the application that I test).But where should I put those test XMLs?I tried with [project_root] /res/xml, but then I get the error: android.content.res.Resources $NotFoundException: Resource ID #0x7f040000 type #0x1c is not valid at android.content. res. Resources. loadXml ResourceParser(Resources.java:1870)at android.content.res. Resources. getXml(Resources. java:779) Does that mean that the xml is invalid, or that android couldn't find the XML file?(I use the same XML that comes from the server - copied it from the firebug's net panel and pasted into the file).Can I somehow read that XML as a text file, since etContext(). getResources() .getXml (R.xml.test_response1) returns XmlResourceParser instead of String (which I'd prefer)?

I'm using the UI test monkey tool provided with android. This is a consistent error I see and wonder how I can avoid it.
Somehow the test app will rotate the orientation of my app such that the emulator window is still in portrait orientation, but the screen surface is in a landscape orientation. When in this configuration, any time you click on an EditText, a system exception gets thrown:
"The application OpenWnn (process jp.co.omronsoft.openwnn) has stopped unexpectedly. Please try again."
So this OpenWnn process is not mine, it looks like it handles display of the virtual keyboard. When in this odd orientation mode, and you try to click in an EditText, I can see the virtual keyboard try to slide in from the left side of the screen, then that exception gets thrown.
I'm not sure what orientation this is, because it's not the normal landscape orientation you get by hitting ctrl + F11. In fact, the virtual keyboard shouldn't even be trying to display itself in landscape mode? Much less from the left side of the emulator?

When I am trying to build my application as a part of image I am getting the following error :
E/dalvikvm( 1334): Can't open dex cache '/data/dalvik-cache/ system@a...@test.apk@classes.dex': No such file or directory I/dalvikvm( 1334): Unable to open or create cache for /system/app/ test.apk (/data/dalvik-cache/system@a...@test.apk@classes.dex) E/Util( 1334): Class Not Found : java.lang.ClassNotFoundException:
But when I push the apk manually to the device (into system/app), it works fine.
I am wondering why is it so as both ways the apk is present at system/ app only.

I have never used JUnit before, and now I'm trying to set it up on an Android project.My project under test is fairly complex, including some JNI, but my test project, at the moment, is completely trivial. I have found many examples (that look totally different) online of how to make a test project, but it seems that no matter which one I follow, I get the same results.Here's my JUnit project code:package com.mycompany.myproject.test;
import android.test.AndroidTestCase;public class SimpleTestCaseExample extends Android TestCase {public void test_testOne() {fail("Just Always Fail");When I run, I see the following in Logcat:
stdout INSTRUMENTATION_STATUS: numtests=2
stdout INSTRUMENTATION_STATUS: test=test_testOne
stdout INSTRUMENTATION_STATUS_CODE: 0
stdout INSTRUMENTATION_STATUS: id=InstrumentationTestRunner
stdout INSTRUMENTATION_STATUS: current=2
stdout INSTRUMENTATION_STATUS: class=com.mycompany.myproject.test.SimpleTestCaseExample
stdout INSTRUMENTATION_STATUS: stream=
stdout INSTRUMENTATION_STATUS: numtests=2
stdout INSTRUMENTATION_STATUS: test=testAndroidTestCaseSetupProperly
stdout INSTRUMENTATION_STATUS_CODE: 1
stdout INSTRUMENTATION_STATUS: id=InstrumentationTestRunner
stdout INSTRUMENTATION_STATUS: current=2
stdout INSTRUMENTATION_STATUS: class=com.mycompany.myproject.test.SimpleTestCaseExample
stdout INSTRUMENTATION_STATUS: stream=.
stdout INSTRUMENTATION_STATUS: numtests=2
stdout INSTRUMENTATION_STATUS: test=testAndroidTestCaseSetupProperly
stdout INSTRUMENTATION_STATUS_CODE: 0
stdout INSTRUMENTATION_RESULT: stream=
stdout Test results for InstrumentationTestRunner=..
stdout Time: 0.07
stdout OK (2 tests)
stdout INSTRUMENTATION_CODE: -1
But, I get the following in the Console:Launching instrumentation android.test. Instrumentation TestRunner on device emulator-5554 Collecting test information Test run failed: No test results I have tried a variety of different things, messing with the basic TestCase class, or the TestSuite class, or a variety of other options. I tried to just go for the most trivial example because I'm really still trying to learn how this works.Whatever I try, I see this error.

Automated Functional Testing..First of all let me make you all aware that I'm a developer and what you are going to read further is a developer's account, so it may sound to you like a layman tester. But what I'm going to share is something which has been very helpful to me to 'functionally' test the web application our team has been building and I thought this may help you as well. So even if you are a tester, try to think the way developer's think for some time, I'm sure this would be useful to you too. Before I go ahead, I think we all understand that Functional Testing is testing the functionality of our application which means you'd probably be going through a login using some credentials, clicking some links, verifying some outputs - in simplest terms. Now just give it a thought that if you can automate these i.e. invest some time for once and then while you are sipping a cup of coffee, someone is testing what you coded. Change your code 10 times and run your test 10 times to ensure nothing breaks, so easy. Not just this if you have continuous integration server setup which runs your tests, you'd come to know immediately if and when someone else broke your code. Believe me ones who have used it, feel it is fantastic.
There are a variety of tools available for this over internet each with pros/cons but I'm going to share some info here about one which I liked very much and have been using for a while now. I'd also share why I preferred it over others.Ok, no longer prolonging the suspense the tool I'm talking about is called Canoo WebTest (webtest.canoo.com) which is a free Open Source tool for automated testing of web applications in a very effective way. The primary reason why I liked it is that it is FAST; very fast ... most of the test cases that I've written are executed in less than a minute and that too over remote applications deployed on servers on the other side of globe. Second reason for liking it so much is the ease of writing; very quickly you can build up your tests. Though they have released a WebTest recorder plug-in which when installed in Mozilla Firefox can record the script for you, but believe me the more you start writing there test cases, the less reliant you will become on the recorder. Third thing is these tests do not use a browser so that completely eliminated browser-specific issues which some tools are plagued with.

I have an ordinary project with JUnit tests that are connected to the classes in my Android Project. I want my server to run some JUnit tests in my testproject everytime I commit my code from my Android Project.Is there a best practise to do this?So far I only managed to run the tests when they are a part of a while the JUnit tests and Android classes are separated into 2 different projects, since JUnit runs on JVM and Android in an emulator on DVM (Dalvik Virtual Machine).
