Cannot load project defined classes

[Andrew Budker]

Hi,

I'm seeing a similar issue to some other people on this group when I
try and mock classes which I have defined in my Android Project (I can
successfully mock the Object.class).

Here is the output:

Any thoughts?

Hi Andrew,

I think the annotation processor is not able to find com.abudker.dexit.Dependency. Please ensure you have followed the instructions in http://android-mock.googlecode.com/files/AndroidMockinEclipse.pdf correctly.

Also, try to add the path to com.abudker.dexit.Dependency explicitly under "Factory Path" (as shown in the AndroidMockinEclipse.pdf) and check if it still complains.

Thanks.

Hi,

I followed the instructions contained in that pdf (and also found the discussion noting that it was out of date). I have tried to set this up several times from scratch and i see the same issue over and over again. There are two problems:

1. Android-mock doesn't seem to know about the classes defined by the application under test if you specify the bin directory. (Turns out the instructions are wrong and if you set a factory path pointing to AppUnderTest/bin/classes this works)

2. When i actually deploy the tests, I fail to load the mocks that I have generated (the instructions for setting it up in eclipse mention downloading the AndroidMockRuntime, but never actually use include it in the apk). I have tried setting the AndroidRuntime, and the AndroidGenerator as exported and I see the same result for both custom objects and android objects. 

Example stack trace:

java.lang.RuntimeException: Could not find mock for java.lang.Object  -- Make sure to run the MockGenerator.jar on your test jar, and to build the Android test APK using the modified jar created by MockGenerator

Hi Andrew,

I am glad you figured out #1. The instructions are old and need to be updated. I think it was with ADT 14.0 update after which the android project bin directory was changed to bin/classes.

For #2, Please make sure that <TEST_PROJECT_FOLDER>/bin/classes is set as the bin_dir. That will ensure the generated mocks are saved to .../bin/classes directory and package with your APK.
