Subject: [PATCH 1/3] Updated dependency to TestContainer to 2.0

Configured maven build with Mockito agent to support JDK21+ where dynamic class definitions aren't allowed by default anymore.

Removed some old references to org.junit.Assert, which is deprecated and no longer available after the upgrade.

TestContainers update is (apparently) required for compatibility with new Docker APIs.
