7 years ago I'm running into this same issue. In case more information is required that could help solve this issue please let me know! The output of my (first Roboelectric test) is as follows:
WARNING: No manifest file found at .\AndroidManifest.xml.
Falling back to the Android OS resources only.
To remove this warning, annotate your test class with @Config(manifest=Config.NONE).

Description
We have come across an issue which causes exceptions during unit tests that utilise the Aalto extension of StAX since the 3.3.2 release of roboletric. When running tests with the RoboletricTestRunner, we get the following exception:
After some investigation on this issue I concluded that the Aalto concrete implementation of
XMLInputFactorysimply couldn't be found, so I created a custom Test Runner subclassing RoboletricTestRunner and set thejavax.xml.stream.XMLInputFactorysystem property tocom.fasterxml.aalto.stax.InputFactoryImpllike such:While this resolved the first exception, it created another:
InputFactoryImpldoes extend by way of a few a classes theXMLInputFactoryclass, so the exception isn't because of an actual casting issue. Upon further investigation it's lead me to believe that this might be a Class Loader issue. It's my understanding Roboletric uses its own class loader, and that if this is not loading the Aalto extension/implementation of StAX then the classes are not visible to it at runtime, hence the exception when trying to use theInputFactoryImplclass.Is it possible to somehow force Roboletric's class loader to load all of the dependencies in the depedencies closure in build.gradle so that all classes are visible during testing?
Steps to Reproduce
Our project is a little more complex so haven't split out into a unique project replicating the issue but the basic gist is to do the following:
Create an Android project with the following compile dependencies: aalto-xml-android:0.9.8 jackson-dataformat-xml-android:2.2.3 stax-api-android:1.0 stax2-api-android:3.1.1
and testCompile ('org.robolectric:robolectric:3.3.2')
Create a test class using RoboletricTestRunner and run a test.
