Mobot Solution

Since 2018, Mobot is proud to help the mobile engineering team at Sandboxx ship quality, bug-free apps to Google Play and the Apple App Store week after week.

Each week, Mobot executes a regression test suite on real iOS and Android devices that cover every possible method a Sandboxx user can log in and send a Letter. This

grants the engineering team the peace of mind to know their core app functionality continues to reach every user while they continue building a great product. 

The Results

● Within 3 months of working with Mobot, Sandboxx’s App Store rating increased from 4.2 to 4.8. 

● Since July 2018, 100% of the test cycles that Sandboxx have run with Mobot have resulted in at least 1 bug per cycle being discovered and filed into their bug tracking system. 

● 62% of bugs were promptly resolved during the same release, with the rest triaged for upcoming releases. 

● Mobot has discovered bugs that would have been difficult/impossible to replicate using a traditional test automation framework, such as a memory leak triggered by a third-party software library on older iOS devices and interactions with third-party authentication apps. 

● Within 12-24 hours of a test request from Sandboxx, Mobot executes and shares results with their engineering team.
