ClassNotFoundException even for String.class

[Macarse]

Hi,

I am trying to run tests with mocks from Eclipse.
I continue getting:
[2010-11-12 10:13:22 - ioc_test] Test run failed:
java.lang.ClassNotFoundException

My test:

@UsesMocks(String.class)
public void testObject() {
String myMockObject = AndroidMock.createMock(String.class);
AndroidMock.expect(myMockObject.toString()).andReturn("");
AndroidMock.replay(myMockObject);
assertEquals("", myMockObject.toString());
AndroidMock.verify(myMockObject);
}

In the AnnotationProcessor.log I get:

It happens the same when I try to mock classes of my own.
What can be wrong?

Thanks.

Hi,

First off, I'm guessing that you're using String as an example or proof of concept. But as a final class, it's not mockable. That's why it's throwing up this exception here.

I made some major recent changes to how sdk classes are mocked and it seems to have caused this exception to be thrown before the check-and-warn code.

Second, from your error output I see that you haven't added the frameworks mock jar file to your annotation processor factory path. This is a new step that I haven't had the chance to add to the instructions yet. There is an email on the discussion group related to this with a title similar to "New Android Mock".

In summary, you need to do the same process as you did for ANDROID_JAR (or similar), the (Annotations -> Factory Path) variable you added during setup to point to the android ask jar file. Create another one with a name like ANDROID_FRAMEWORK_MOCKS and point that at the file "android_framework_mocks.jar" which is in the bin folder of your android mock install folder.

Third, if you're seeing a ClassNotFound on your own classes, it might be that you're mocking a class that references a class in a Referenced Library. Android Test projects cannot see the contents of any Android project referenced libraries. Even if you're not mocking a jar from inside such a jar, if the class being mocked has a method whose signature refers to such a class, you'll have trouble.

Check the stack trace to see which class is not found then add the jar containing that class to the build path of your test project.

NOTE: to be clear this is not the factory path of step 2. This is your normal test project's Referenced Libraries.

If those steps don't sort out the problems let me know. I'm not sure why you would see this same stack trace with your own classes except in the case I described in step 3. But if you're still having trouble let me know and send me the stack trace and I'll see what I can figure out.

Thanks,

Steve

Thanks for the feedback. I couldn't fix it in Eclipse but it work like
charm from maven.

I made a blog post about it:

Steve,

I think I've also hit the same problem. I remember your comment about
missing jars in the test project, but I've got the jar in the build
path and i'm still seeing this exception in the mock generator logs
(Gson is in the constructor of one of the mocked classes; I believe
Gson is a final class). Any way around this?

Do you know which jar contains com.google.gain.Gson? I suspect it isn't android.jar. It sounds like a Google Api. You'll want to make sure it's in the factory classpath for the test project in the same way as you have android.jar (ANDROID_RUNTIME).

Hi all,

I'm pretty new to this and have a problem looking pretty much like
Mike Liu's, see build log below.
Am I missing android/text/Editable stuff or?

I can't find info about this. Can anyone point my in the right
direction for "setting factory classpath"?
I'm compiling from command line and all I've done is to add
AndroidMockGenerator.jar to the classpath for javac.

This sounds a lot like the "android.jar" missing from your Annotations Factory Classpath.

Take a look for ANDROID_RUNTIME in the setup PDF file (http://android-mock.googlecode.com/files/AndroidMockInEclipse-1.0.1.pdf)  (pages 4-7)

As a quick summary, you want to Open up the project properties, turn on Annotation processing, then drill down the menus to get to Factory Path.  From there, add a reference to the android.jar file as ANDROID_RUNTIME as a new classpath variable.  The PDF linked above has more detailed steps.

Let me know if you still have troubles.  Believe it or not, closing and reopening Eclipse can fix such problems too, assuming your setup is correct.

[Mike Liu]

You'll want to take a look at apt:
http://download.oracle.com/javase/1.5.0/docs/guide/apt/GettingStarted.html

Thanks for the information!

I need to get it to work from command line because of our build
system.
Is it possible to set the Annotations factory classpath when compiling
with javac? Or is this where I need to use apt?

//Bo

[Stephen Woodward]

Command line is no problem. Add android.jar to your classpath. Same for the mock generator jar.

[Agilen]

Hi Stephen,

Thanks a lot man :)

I was not able to create the Mock for my own class. I just close and
open the Eclipse and Emulator. It resolved the problem.

Thanks,
Agilen

Hi Stephen,

I'm getting the same error, even after adding the
android_framework_mocks.jar to the factory classpath.

[Stephen Woodward]

That's very odd. A couple of questions.

1. are you really trying to mock java.lang.Object? You should be able to but there's no reason to do so except to test Android mock.

2. It found the framework mocks jar (see 12:05:02 pm logs). Does the jar contain a class called v15.genmocks.java.lang.ObjectDelegateInterface?

No, android.content.ContentResolver is what I really want to mock... But same issue occurs.

2. It found the framework mocks jar (see 12:05:02 pm logs). Does the jar contain a class called v15.genmocks.java.lang.ObjectDelegateInterface?

I tried checking the jar and it turns out it wasn't world-readable *facepalm*. I fixed that and mocking Object works now, but ContentResolver does not.

(As an aside: How do I remove Object from the list of classes to mock? I don't have any @UsesMocks(Object.class) annotations anywhere anymore)

The jar contains v15.genmocks.android.content.ContentResolverDelegateSubclass, as well as v15.genmocks.android.content.ContentResolverDelegateInterface

[Shea Levy]

Ok, I don't get the error when I mock out MockContentResolver. Can android-mock handle abstract classes?

[Stephen Woodward]

If you can subclass it you can mock it.

Try quitting and restarting eclipse to drop the Object mocking. It caches a lot of stale info.

The error is very strange especially at Processing time. I'll need to think about it a while. But note that static and final methods can't be mocked so you might not get much benefit from mocking Content Resolver anyhow... the ask provided stub (called mock) should be a good workaround.

I have added the path for the framework jar and restarted eclipse and
emulators to no avail. Interestingly I do not see that the log file or
bin/genmocks is being generated either.

[Stephen Woodward]

Hi Jimmy,

It sounds like a setup problem, especially with no annotation log and no bin/genmocks created.  I'd make sure that you have the eclipse project set correctly to use annotation processors (the early eclipse setup steps in the eclipse android mock setup doc).  It may be something like a missing checkbox.

And just for sanity's sake, you do have an @UsesMocks{ Activity.class } on your test method or class, right?  (I'm guessing yes, but just in case).

Another thing you can do is to try it from the command line.

Try compiling your android code with AndroidMockGenerator.jar and android_framework_mocks.jar in the classpath.  I'm thinking something like:

javac -cp bin/android_framework_mocks.jar:bin/AndroidMockGenerator.jar:lib/android/android_v21.jar <your android java files>        (replace : with ; and / with \ for Windows)

See if this compiles correctly, and you should see on your screen the same output that the Annotation Processor log file would give you.  If it doesn't generate the classes correctly, you could copy and paste that into an email to me for further analysis.

Thanks,

Steve

I have also attached the log file. 

I have the android-framework-mocks.jar on the factory path, and also the path to the android.jar there as well. 

Strangely, I am able to mock an OnClickListener (android.view.View.OnClickListener) -- I am able to get a non-null reference from 

AndroidMock.createNiceMock(View.OnClickListener.class).

Could you please give me any pointers as to what might be wrong?

Thank you very much for your help!

Daniela

What is your app's target API level? Based on the output "genmocks.android.widget.TextViewDelegateInterface", it looks like you are using an API level (10 or higher) that is not supported by your version of AndroidMock.

The latest and greatest AndroidMock (from code.google.com) added support for API level 10-12 (gingerbread and honeycomb).

Hi Rob,

Thanks for your reply! I'm using Android 2.1.

Hmm, I have same problem. Setup my eclipse test project like described in AndroidMockinEclipse.pdf. But in ActivityInstrumentationTestCase2->testPreConditions() when I try use AndroidMock.class, I get "java.lang.NoClassDefFoundError: com.google.android.testing.mocking.AndroidMock".
