Caching the Spring Context in Tests: How to Speed Up Testing

on YouTube ↗48m

" summary

The talk explains how to speed up Java/Spring test runs by reusing cached Spring ApplicationContexts during local development the same way CI/CD does, avoiding JVM shutdown between test runs. It describes using hotswap tools—DCEVM with HotSwapAgent—to allow code updates without restarting the cached JVM, and presents an IntelliJ IDEA plugin that implements this workflow plus guidance on writing HotSwapAgent plugins.
