Description

Most of the tests are either moved to a different repo like connectors or rewritten in powermock free way.
Powermock itself became unmaintained (latest release was in 2020 https://github.com/powermock/powermock/releases/tag/powermock-2.0.9)
and latest commit 2 years ago https://github.com/powermock/powermock

also there is no support for junit5 (the request to support it and even PR from junit5 maintainers is ready for review since Feb 2023 https://github.com/powermock/powermock/pull/1146, however still no feedback from maintainers...)
