Testcontainers - a Year-in-review
summary
Project shows concrete changes: a tiny sidecar container handles cleanup so zombie containers disappear when the JVM is killed, dynamic port binding and wait strategies make startup reliable, and JDBC/HTTP/TCP checks confirm service readiness. Per-test fresh DB containers cost ~4–5s each, so reusable containers (preview since 1.12.3) plus schema reset speed iterations dramatically. New transports (okhttp), Windows and Docker Compose improvements, copyFileToContainer, and modules for Kafka, Postgres, Couchbase, Cassandra, DB2, Cockroach, RabbitMQ appear; repo exceeds ~3,000 stars.
