android-discuss, Need help in running the android junit test case for andriod APIDemo in eclipse

 ou will never really be able to just use the default Run as JUnit test action.



This is because this setups up the tests to run using the system

library of the project which, for Android project, is android.jar.

android.jar in the SDK is only stubbed methods/classes, and contains no code.



You can run unit tests by setting up Eclipse using the follow

instructions: http://code.google.com/android/kb/troubleshooting.html#addjunit



Note that this will only work for tests not using the Android APIs.



If you wish to run true android test, please use instrumentations

running on the device.

See 

http://code.google.com/android/reference/android/test/InstrumentationTestRunner.html

for more information.



The information from Diego to setup the test runners for ApiDemos is

good, except that you don't need to create a new project and copy

things over, you can simply create a project for the existing source

(you will need to link the apidemos project in your build path).

Thanks. But most likely most of my classes will use android APIs, so

using this to unit-test is not that common, right?

Or I am mis-understanding the condition.

I would like to have 1 way to unit-test my android code.













Thank you. I have followed Diego instructions, and I finally get that to work.

But you mention that there a way not to create a new project.

Can you please tell me how to do that?



I have create an 'apidemos' project in eclipse, but the 'tests'

directory is not in the build path. Hence they are not compile.



So what should I do to run the code 'tests' code without creating a

new project like Diego described.



Thank you for any tips.

 sing the "new android project" wizard, you can create a project from

existing source.

This is probably what you used to create a project for ApiDemos. Just

use it again for the tests project (point the wizard to

<sdk>/samples/ApiDemos/tests).



The compilation problem is because the tests project doesn't know the

ApiDemos classes until you tell it where they are.

Right click the tests project in the package Explorer and choose Build

Path > Configure Build Path.

In the "Projects" tab, click Add and choose your ApiDemos project.



Because deployment of instrumentation projects is not supported in ADT

you will have install ApiDemos and your test project manually.



We do intend to improve this workflow in the future.

 hank you.  Xavier,



Can you please tell me if this will run other vanilla junit test

cases? The ones just inherit from Junit framework, not the ones which

are sub-classed from Google TestCase classes?



Thank you.

 i,



I tried that again, but it does not work now, for some reason.



I did load 'ApiDemos' project first, but I don't see the 'Test for Api

Demo' in the 'Instrumentation.' screen.

Then, I manually load the 'ApiDemosTest2' project again, I still don't

see the  'Test for Api Demo'.



But from the Eclipse output, I do see that both apk has been installed.



Any idea why it does not work?

Thank you for any help.
