Hi,
I have a question on the project set-up - this may be a bug in SDK.
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 {
...
}
public class FooImpl implements IFoo {
...
}
2)
Main project: AndroidFoo
public class FooAndroidImpl implements IFoo {
...
}
public class Bar {
...
}
3)
Test Project: AndroidFooTest
public class FooTester extends AndroidTestCase {
// breaks
void test1AndroidImplWithInterfaceInLibraryProject() {
Object o = new FooAndroidImpl(); // Gets NoClassDefFoundError
on SDK 2.0 and obscure "Test run failed" on 1.6 and 1.5
}
// works
void test2AndroidOnly() {
Object o = new Bar(); // works fine -> no exceptions even
though the class sits in the same package as the one that was throwing
exceptions in case 1
}
// works
void test3LibraryProjectOnly() {
Object o = new FooImpl(); // works fine -> no exceptions even
though the class sits in the same package as interface of the test1
}
}
Thanks in advance.
