Abstract:
"The Regression Test Selection (RTS) tool presented in this document addresses the challenge
of efficiently selecting and executing regression tests in microservices environments.
Traditional regression testing approaches can be time-consuming and resource-intensive,
leading to longer test cycles and hindering the agility of microservices-based applications.
The RTS tool addresses the problem by employing intelligent techniques to identify and select
the precise subset of tests that are impacted by system changes. It achieves this by utilizing a
blend of static and dynamic analysis techniques to extract mappings between tests and services
utilizing both source artifacts from source repositories and distributed traces from observability
tools.
In an experimental setup on Google Cloud when executed against a hipster shop microservice
deployment the tool performed with 82.55% testing time cost savings rate indicating the
efficiency in terms of execution time. On average, the F measure indicating overall efficiency
of the RTS tool recorded to be 62.16%. With the test and evaluation results, the RTS tool
demonstrated its capability to streamline regression testing workflows, significantly decrease
testing effort and time, and expedite feedback cycles in modern, agile organizations."
