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 […]

J-Fall 2019: Jaap Coomans – Mocking your microservices with mock-server

How can I test my microservices? It’s an often heard question that leads to a lot of debate. Deployment and interdependence with other services are the challenges we’re facing there.

Survivorship bias causes you to draw false conclusions because you mostly heard about successes, but hardly ever about failures. Yet failures provide us with lots of valuable knowledge: when not to apply a certain technique, pattern or […]
