Primary Challenge
Ensuring app stability and performance at massive scale with efficient and comprehensive testing
Key Metrics
\- 80% reduction in Android app crashes\- Tens of thousands of test cases generated and run daily\- 75% of Sapienz reports actionable and result in fixes\- Near real-time bug detection and reporting\- Extremely low false-positive rate
The Problem
Manual test design was time-consuming, limited in coverage, and unable to keep pace with rapid development cycles
The Solution
Sapienz uses multi-objective search-based software engineering (SBSE) to automatically design system-level test cases, run them on hundreds to thousands of emulators, and report results directly to developers via continuous integration tools
Results
\- Dramatically faster bug detection and resolution\- Improved test coverage including hard-to-find edge cases\- Reduced crash rates and improved app stability\- Friction-free integration into developer workflows\- Scalable testing infrastructure running 24/7 on thousands of emulators
“Sapienz has transformed our testing process, enabling engineers to fix issues within minutes of code submission and significantly reducing app crashes.”
