Android :: Error Occur When Try To Run Junit Test Case On Emulator?
Jan 9, 2010
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:

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.

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 am building an Android hello world application in Netbeans. It's building properly and I am able to run in the emulator also. But when creating and running the Junit test I get a java.lang.NoClassDefFoundError.

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();}

From 2.0 the cts is freely downloadable from android's repository.
But there is no documents about it.
Does anyone can tell me:
How to build cts? Is there a standard procedure? How to run cts? How to add customized test case?
Here, share my experience. After repo sync all source, you can't directly run "make" to build all source.
You will get some errors.
Now, I'am trying to first build android source without cts, and then build cts alone.
Also, here are some reference for run cts:

2.build cts (move cts back).

There is no exception on medtPriceValue.setText("50");.but there is one on the screen for medtSalePercent.setText("10");

Was wondering if there's any way to test Gestures (eg: Fling) on the Emulator.
I saw a project on google code that lets people simulate the accelerometer, but none of Gestures.

Finally strace gave me this:
CODE:................
And several other attempts to call "link" that also fail (sshfs does not support hard links).
Is it possible to change the emulator's behavior to create lock files somewhere in /tmp (using some hash of image path as lock file name)? I am OK to try this myself: which repositories from https://android.git.kernel.org/ are necessary to rebuild the emulator alone, and where in the sources is the code responsible for image locks?

Has anyone successfully compiled the android kernel and tested it in the Android emulator, and if so is there anything that special that needs to be done? Documentation for the SDK is excellent, however documentation for compiling the kernel and setting up a custom machine in the emulator has been hard for me to find.

I'm using the 1.5 SDK. I read in 1.0 that rotating the device would cause onCreate() to be called in our apps (possibly recreating the entire app?). Is there a way to test rotating the device in the emulator? I just want to see what happens, I don't have a device to test this. Will the behavior be the same for 1.5 as it was in 1.0?
