Field Testing of Software Applications [PDF]

open access: yes2017 IEEE/ACM 39th International Conference on Software Engineering Companion (ICSE-C), 2017
When interacting with their software systems, users may have to deal with problems like crashes, failures, and program instability. Faulty software running in the field is not only the consequence of ineffective in-house verification and validation techniques, but it is also due to the complexity and diversity of the interactions between an application
