J-Fall 2019: Job Rooseman & Ernst Noorlander – Continue performance validatie

De Belastingdienst heeft bijna 100 Java ontwikkelteams waarvan de meeste, tijdens de ontwikkeling van de Java applicaties en services, meerdere performance testen uitvoeren. Vaak worden deze testen geautomatiseerd in de delivery pipeline uitgevoerd. Geautomatiseerd performance testen is de eerste stap naar een aanpak die de “shift-left” (lees performance engineering) wordt genoemd. De volgende stap in […]
