Guiding App Testing with Mined Interaction Models

Test generators for graphical user interfaces must constantly choose which UI element to interact with, and how. We guide this choice by mining associations between UI elements and their interactions from the most common applications. Once mined, the resulting UI interaction model can be easily applied to new apps and new test generators. In our experiments, the mined interaction models lead to code coverage improvements of 19.41% and 43.03% on average on two state-of-the-art tools (Droidmate and Droidbot), when executing the same number of actions.
