Android :: Is It Unit Test Or An Integration Test?

Nov 9, 2010

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.

Android :: How To Transfer Test Fixture File To Device From Unit Test Application?

Sep 24, 2010

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?

Android :: Error When Unit Test With Activity Instrumentation Test Case 2?

Aug 23, 2009

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();}

Android :: Way To Unit Test Phone Library App?

Nov 16, 2010

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.

Android :: Unit Test Build Error

Mar 8, 2010

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 ?

Android :: Unit Testing With Test Only Assets

Jul 3, 2009

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.

Android :: How To Refactor Class So I Can Unit Test It?

May 21, 2010

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?

Android :: Unnecessarily Hard To Unit Test?

Oct 8, 2009

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 );

Android :: Relative Layout Unit Test Setup

Mar 20, 2010

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)

What should I change in my setUp() code to make the test run properly ?

Android :: How Can I Unit Test Activity That Acts On Accelerometer?

May 10, 2010

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?

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..............

Android :: How Do I Sync Message Queue Thread In Unit Test?

Mar 30, 2010

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?

Android :: Test Data Sources In Android Unit Testing

Jan 27, 2010

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)?

Android :: Getting Test Run Failed No Test Results?

Aug 11, 2010

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.

Missing Target Class To Test In Test Application?

Nov 10, 2011

I have a project (that compiles and runs in the emulator.) I have a test project that tests part of this project. This test project also compiles with no problems, but when I try to run (test) it in the emulator, I get a NoClassDefFoundError exception on one of the classes my test class tests (I hope that made sense!) when it starts to run in the emulator. This is coming out of the adb log. I looked in the bin directory (of the test project) for the missing class, but could not find it... Should it be there? I found no reference (apk, etc) of the project I am trying to test either in the test projects bin directory. How does the test project get the classes it needs to test against (in the classpath, I assume.) How do the tested classes get moved to the emulator? I did try running the app before testing, so I know it is installed and runs correctly. BTW, I am using netbeans with the nbandroid plugin.

Android :: Way To Test Serialization?

Oct 28, 2010

I am trying to implement serialization for an email application on the android (stroring username, password, server etc.), but in order to test it I have to close the application in the emulator and then re-open it to ensure that it looks and finds the file with the serialized objects. The problem is that when I close the application on the emulator uninstalls the application. I close the application with the finish() function. Any inklings as to why this happens? And it wasn't doing it until further along in my development stage.
