Description

https://www.testcontainers.org/test_framework_integration/junit_5/ states:

Note: This extension has only be tested with sequential test execution. Using it with parallel test execution is unsupported and may have unintended side effects.

To me, the entire point of using Test Containers is to speed up parallel builds. I could easily get sequential tests working without it.

Please add support for parallel JUnit builds.

Contributor guide

Research direction
Examine the current JUnit 5 extension's handling of static containers and singleton instances. Design a concurrent container management strategy that supports parallel test execution without interference.
