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. The Tri-Layer Testing Architecture gives a good overview on how to design test solutions easily and quickly. About a decade ago people with advanced knowledge were building test automation frameworks with essentially two separate layers: Test Scripts and Test Libraries. The problem with this Bi-Layer architecture is reusability in other applications, specifically the size and complexity of test libraries along with the application dependent solutions being intertwined made it very difficult, sometimes impossible to reuse them. That's how the idea of the Tri-Layer Testing Architecture was born: why not add a 3rd layer, for all the libraries that can be easily reused anywhere? In this presentation Peter will talk about the main differences of the Bi-Layer and the Tri-Layer architectures. The three layers are Test (runnable test scripts), Business (all the application specific libraries) and Core (independent, reusable libraries). Peter will provide examples from his experience at big fintech and other companies, where he successfully implemented the Tri-Layer Testing Architecture and dramatically lowered the test automation costs for these big companies.
