In the previous chapters, we studied and developed tests for our Android application. Those tests let us evaluate compliance against a specification and allowed us to determine whether the software was behaving correctly or not according to these rules by taking a binary verdict, whether it complied green or not. If all test cases pass, it means our software is behaving as expected. If one of the test cases fails, the software needs to be fixed.

At the same time, we would want to know how the system performs under different situations to analyze other attributes such as usability, speed, response time, and reliability.
