Android :: Failing Android JUnit Tests, Not Breaking My Ant Script Like I Expect
Jun 2, 2010
Failing JUnit tests, not breaking my Ant script like I expect?
My continuous integration server runs an Ant script, which calls something like:
/tests/ant run-tests
My JUnit tests run, but with errors:
CODE:..............
The errors are OK, but my build script keeps going (eventually publishing my broken app to my testers - bad!). What I would expect is for the instrimentaiton to throw a build error, so my continuous integration server (TeamCity in this case) realises that something has gone wrong and reports a broken build. The "failonerror" is already set in the relevant macrodef, so I'm not sure what else I can do?

It appears that Android supports JUnit 3 out of the box.�However, I have some pre-existing JUnit 4 unit tests that I'd like to try on Android. I've tried adding the JUnit 4 jar to eclipse and compiling/ running the tests by pointing a standard JUnit run against them, but nothing seems to happen.�There's no evidence in the eclipse console or the Android emulator that any tests have been run.
Can anyone with knowledge about this subject comment?�Is it even possible to run JUnit 4 tests under Android, and if so, is there a step-by-step explanation as to how to achieve this (preferably under Jetbrains IDEA IDE, and/or Eclipse).

I cannot run android junit tests for classes sitting in main android project that implement interfaces that reside in other included projects. Depending on SDK version I get different errors: from "Test run failed:" on 1.5 and 1.6 and spurious process death to a more polite "NoClassDefFoundError" on SDK 2.0. This happens only on instantiation of classes that reside in the Android project and implement interfaces residing outside that android project. There is no problem instantiating classes that do not fall into this category (i.e. android only or library only classes).
Android project by itself works fine with these classes - it is just the test set-up doesn't and project inclusion/classpath seems to be ok. Test project includes all projects that main project includes. NoClassDefFoundError makes little sense here given that the classloader can see and instantiate classes sitting right next to the ones that do not work. Did anyone else run into this or found a way to set-up android based tests in a multi-project set-up? Below is more detailed set-up and test explanation: 1) Library project: FooLib public interface IFoo { ... }

"Hello, World" and "Hello, Testing" tutorials I created an android application created with Eclipse, along with a corresponding Android Test Project.The tests run fine once. After that, in order for me to run the tests again, I have to close the emulator.If I don't close the emulator, the Eclipse console get stuck on "Installing instrumentation android.test.InstrumentationTestRunner on device emulator-5554"... Nothing happens after that.I've been told to exit out of the application under test in the emulator in order to run the test again. Unfortunately the emulator doesn't have the app pulled up (it's in the normal "locked" position and when unlocked brings up the home screen) and even if I do pull it up then exit, it doesn't seem to let me run my tests again.All the example videos and tutorials all stop at the first run of a test. I have yet to see anyone anywhere run a test a second time!

I have an Android app modeled after the LunarLander example by Google.
I am debugging it on a real device, (Motorola Droid) with Android 2.0.
When the orientation changes, the program crashes on a null pointer Exception.
Logcat from just before crash:
CODE:.............
The first line that worries me is "Something wrong here" at 24:38.620. I have no idea what it means, But I think its due to me not reacting properly to the screen change.
Next I get a debug message that I printed myself from within my own method surfaceChanged() about the new surface dimensions.
Then I print out debug message about whether flies was null. flies is the field that eventually causes the NullPointerException. Its created once, and never written to again for the rest of the program. I know that it was not null before the crash, because it was read several times.
Does anyone have a clue how my private member variable came to be null just by these clues?
I would include code but there is a lot of it and I don't know what would be relevant.

i have a android application which is ready to release .so to release i have put the app in android market .the user can buy the app and can install the app into the phone.android market wont provide any apk file to the user .so normally we need not bother about re distribution of of the app to the unauthorized persons(who didn't buy the app). But what my problem is ,I heard that there is a jail breaking concept which can allow the hacker to get the apk file(installation file) from the device .(even though android market not giving the apk file to the user ).then he can distribute the apk file to all(to unauthorized persons ).how to avoid it.is there any thing to restrict the unauthorized person in using our app,even though he get the apk file . does android market provides the details of the users who has buy the app by paying?

I'm having troubles with ADT and JUnit Testing.
When I use HttpClient classes, my JUnit tests fail with errors like: java.lang.NoClassDefFoundError: org/apache/http/client/HttpClient.
I run my tests in Eclipse as "JUnit Tests" (not "Android JUnit Tests") with the "Android Test Launcher". An idea about how to resolve this problem?

Been slowly building my app and now JUnit is crashing regularly with logcat as below.
There are no other real hints. No relevant code as this can happen at multiple points of the code. There are no other errors or exceptions thrown. As far as I can tell there is plenty of memory left and my app does not appear to have any leaks I can find during a run outside of JUnit.

I'm developing an Android application with database storage.
I want to test some classes that I use to access database.
I've found ActivityInstrumentationTestCase2 to test Activities but I haven't found anything to test classes.
How can I do that? I haven't used jUnit before.

As the first step of the port of my existing Java swing application to Android, I'd like to get the non-UI logic unit tests running on the Android device. The unit tests are written against JUnit 4. It looks like Android 2.2 comes with JUnit 3 as the default. Is there an easy way (or any way) to bootstrap JUnit 4 as the test runner?
I am using IDEA as my dev environment, but it doesn't appear there's any settings that will allow me to specify JUnit 4.

I am in the process of trying to convert a desktop app to Android - and am struggling with some very basic stuff. When I specify a layout including a textview that holds a sizable amount of text wrap_content seems to arbitrarily break in the middle of a word - and I can not find any documentation indicating this can be controlled.

I'm trying to create an activity that presents some data to the user. The data is such that it can be divided into 'words', each being a widget, and sequence of 'words' would form the data ('sentence'?), the ViewGroup widget containing the words. As space required for all 'words' in a 'sentence' would exceed the available horizontal space on the display, I would like to wrap these 'sentences' as you would a normal piece of text.
The following code:
code:...................
yields something like the left picture, but I would want a layout presenting the same widgets like in the right one.
Is there such a layout or combination of layouts and parameters, or do I have to implement my own ViewGroup for this?

Im using the SAXParser object do parse the actual XML.
This is normally done by passing a URL to the XMLReader.Parse method. Because my XML is coming from a POST request to a webservice, I am saving that result as a String and then employing StringReader / InputSource to feed this string back to the XMLReader.Parse method.
However, something strange is happening at the 2001st character of the XMLstring. The 'characters' method of the document handler is being called TWICE in between the startElement and endElement methods, effectively breaking my string (in this case a project title) into two pieces. Because I am instantiating objects in my characters method, I am getting two objects instead of one.
This line, about 2000 chars into the string fires 'characters' two times, breaking between "Lower" and "Level"
<title>SUMC-BOOKSTORE, LOWER LEVEL RENOVATIONS</title>
When I bypass the StringReader / InputSource workaround and feed a flat XML file to XMLReader.Parse, it works absolutely fine.
Something about StringReader and or InputSource is somehow screwing this up.
Here is my method that takes and XML string and parses is through the SAXParser.
CODE:.............
How to not have 'characters' firing off twice when I get to this point in the XML String.
Or, show me how to use a POST request and still pass off the URL to the Parse function.

I am developing a simple android application using eclipse.I wrote a JUnit TestCase for a class I wrote.One particular test compares two 2d arrays so see if they are equal. If they are not equal the test fails.When the test fails I would like to print out the contents of the offending array to see what went wrong. I have tried System.out.print and it doesn't show up in the console or JUnit results.What am I doing wrong?Is it even possible?

After following some instructions on Diego Torres blog I am able to test my classes using the regular Eclipse JUnit test-runner, however I also want to be able to run my unit tests from within the emulated android environment. For now this should make no real difference since the classes I am working on do very basic numerical or networking tasks, but obviously anything which involves the UI or Android API specific functions can only ever be tested on the emulator.
I set up a new run configuration of type AndroidJUnitTest wich uses the ndroid.test.InstrumentationTestRunner, however whenever I fire up the test I get the following error in the console:
[2010-01-09 00:45:23 - Pal1]Uploading Pal1.apk onto device 'emulator-5556'....................

I am creating an Android library that does stuff like http requests, etc, that uses android.jar objects. There will be no manifest or resources, etc, however. What is the best practice regarding the JUnit library to use in this library? DO I use standard JUnit, or the one included in android.jar?

There is an option to create an Android JUnit Project.As far as I am aware the other way is to create a folder in the same project called test which contains the same package name as the existing project.What are the differences between these two methods.

The problem is, that I wanted to write a JUnit-Test for some of my classes - but this stupid Anroid SDK does always lauch this absolutely lame AVD!
So I came up with the idea to move all my non-Android related classes out of the actual Android project into standard Java project. There I can easily test my classes and by adding this standard Java project to the BuildPath of the Android project, I can easily access and use my classes: no error is shown in the IDE - everything is fine.
But if I launch my full application in the AVD, it exits with following exception: NoClassDefFoundError!
I found out, how to run a normal test from an Android project. But why is it not possible to reference to a non-Android project? Regarding code reuse, this is really big disadvantage!

I've got unit tests which are subclasses of AndroidTestCase, I thought they were just taking awhile to run, but for some reason when I run them via Eclipse, they actually run twice. I can verify this in LogCat after the Console outputs "Launching instrumentation android.test.InstrumentationTestRunner on device..." the first run starts, which is only visible via LogCat. Then the JUnit pane comes to life and starts tracking the second run.
