Tri-Layer Testing Architecture

Designing a proper architecture for building your test automation solution is one of the most important knowledge and experience a Test Automation Engineer may possess. Lack of this skill usually results in increased initial development time and higher maintenance costs in the long run.

The Tri-Layer Testing Architecture gives a good overview on how to design test solutions easily and quickly by introducing three distinct framework layers:
- Test Scripts (runnable test scripts)
- Business Logic (all the application specific libraries)
- Core Libraries (independent, reusable libraries)

Péter will provide examples from his experience at big fintech, gaming, fitness and other companies, where he successfully implemented the Tri-Layer Testing Architecture and drastically lowered the test automation costs for these big companies.

Since 2024, the Tri-Layer Testing Architecture is part of the official ISTQB Test Automation Engineering curriculum.
