Jo presented on the challenges of testing micro-services at VIVEPORT and their solution. VIVEPORT uses over 300 micro-services that require function, integration, end-to-end, performance, and production monitoring testing. Some of the challenges included inconsistent business logic, requirement changes impacting schedules, and the effort of regression testing. To address these, VIVEPORT implemented a process where product owners define test plans, developers implement features and prepare tests, and SDETs execute and review tests. This aligned teams, improved quality, and reduced testing effort so that all features could be tested.
