We are building a complex Android application consisting of many screens and workflows spread across many Activities. Our workflows are similar to what you might see on a Bank's ATM machine, for example, there is an Activity to login in that transitions to a main menu Activity which can transition to other activities based on the user's choices.
Since we have so many workflows we need to create automated tests that span multiple activities so we can test a workflow from end to end. For example, using the ATM example, we would want to enter a valid PIN, verify that sends us to the main menu, choose withdraw cash, verify that we are on the withdraw cash screen, etc., etc., and eventually find ourselves back on the main menu or "logged" out.
We've toyed with the test APIs that come with Android (e.g. ActivityInstrumentationTestCase2) and also with Positron, but neither seem capable of testing beyond the bounds of a single Activity, and while we can find some utility in these tools for some unit testing, they won't meet our needs for testing scenarios that cut across multiple Activities.
We are open to an xUnit framework, scripting, GUI recorders/playbacks, etc. and would appreciate any advice.
