Testcontainers: a year-in-review
summary
Testcontainers is a JVM library that spins up throwaway Docker instances of databases, browsers and services; the demo wires a Spring Boot app to TC PostgreSQL, Redis and a mockserver so JDBC URLs with the TC prefix lazily start containers and tests pass in seconds. Recent additions: Kafka and Couchbase modules, HTTP (okhttp) transport, Windows pipe support, JUnit 5 integration and a reusable containers mode that cuts startup from ~8s to under 200ms (Postgres ~1.5s), with reuse TTLs disabled on CI.
