Definition of tests designed for mobile devices, which were later executed in real iOS and Android devices. The most widely used devices and their features were analyzed with the objective of selecting a representative group of devices and operative system versions, which were later used to execute tests.

Usability tests based on the specifications provided by each of the platforms (iOS and Android) with the objective of ensuring the best experience for the end user.

Planning and execution of performance tests, specifically load tests, for the services used by mobile applications. Test scripts were designed with JMeter, while the execution was performed using services provided by Blazemeter to generate load through nodes located in AWS.
