Hey all! Have a great news. First android instrumentation test in MockK is working. This is first step. A lot of work pending to make it real. Next expecting 250 JVM tests to pass. I took https://github.com/linkedin/dexmaker implementation, so it is doing inlining on the fly(no need to open-all). It is a lot more powerful than mockito. https://github.com/oleksiyp/mockk/pull/68/files
