Testen van microservices en gedistribueerde systemen is complexer dan testen van monoliths — services communiceren over netwerken, met onafhankelijke deployment en gedistribueerde foutmodes. Dit vereist strategieën zoals contract testing, service-level testing, en zorgvuldige integration/E2E-benaderingen.
De uitdagingen
Distributed systems are harder to test than monoliths:
→ many SERVICES interacting over the NETWORK (latency, failures, partial outages)
→ services deployed INDEPENDENTLY → integration/compatibility concerns
→ E2E testing across many services is SLOW, BRITTLE, and complex to set up
→ distributed failure modes (a service down, slow, returning errors)
