From: Jindrich Novy Date: Thu, 14 Aug 2025 10:33:00 +0200 Subject: Replace Go tests with BATS and remove Go dependency Reimplemented all tests from Go to BATS framework, providing comprehensive test coverage while eliminating Go build dependencies. Added 52 BATS tests covering basic functionality, container logging, k8s log rotation, and full runtime integration with real container execution.
