I am trying test an Activity derived from FragmentActivity(from android-support-v4.jar) using ActivityInstrumentationTestCase2. The android-support-v4.jar is located in the libs folder of my main project(tested project). To make the test project pass the build, I add add a link from the main project to the test project with command "ln ../mainProject/libs/android-support-v4.jar ./libs/android-support-v4.jar" in my test project root directory. It is recommended by http://dtmilano.blogspot.com/2009/12/android-testing-external-libraries.html?showComment=1348480869133. Following the guideline from the blog, I can run the test with Eclipse successfully. However, when I try to run the test with command "ant clean debug install test", I will always met the below exception:
[exec] android.test.suitebuilder.TestSuiteBuilder$FailedToCreateTests:

Here is the snap of test code:
public class QuestionListActivityTest extends ActivityInstrumentationTestCase2<QuestionListActivity>{
private Solo solo;
private FragmentActivity activity;
public QuestionListActivityTest() {
super(QuestionListActivity.class); **// the exception happened here**
}
...
}
I am using android sdk R15. The test was run with the emulator. Does anybody know how to solve it? I really need to run it with ant so as to integrate with hudson. Thanks in advance!
