Description

• As stated in [Improvement][UT] Upgrade junit to 5.+ #10976 (comment), Powermock does not and will not support jUnit 5. We need to remove the dependency on Powermock.
• One possible way is to use a high version (greater than 3.4.0) of Mockito to mock static method, see: https://wttech.blog/blog/2020/mocking-static-methods-made-possible-in-mockito-3.4.0/

• Furthermore, we could use Spotless to block the usage of Powermock. [Improvement][Test] Block the usage of Powermock #11637

Sub-Tasks

I have split the task into six sub-tasks by workload:

• Remove Powermock in dolphinscheduler-api [Improvement][Test] Remove Powermock in dolphinscheduler-api #12144
• Remove Powermock in dolphinscheduler-datasource-plugin [Improvement][Test] Remove powermock in datasource-plugin module #12179
• Remove Powermock in dolphinscheduler-master [Improvement][Test] Remove Powermock in dolphinscheduler-master #12124
• Remove Powermock in dolphinscheduler-common, dolphinscheduler-alert, dolphinscheduler-log-server, dolphinscheduler-spi, dolphinscheduler-worker [Improvement][Test] Remove powermock in common, alert, worker, etc. modules #12208
• Remove Powermock in dolphinscheduler-service, dolphinscheduler-server [Improvement][Test] Remove Powermock in dolphinscheduler-service and dolphinscheduler-server #12155
• Remove Powermock in dolphinscheduler-task-plugin [Improvement][Test] Remove Powermock in dolphinscheduler-task-plugin #12150

Examples

Currently we have several typical scenarios where we heavily rely on Powermock

1. Mock static class
2. Suppress Static Initialization Error
3. Access private method in UT
   ... (to be continued)

I will give some examples and corresponding solutions for these scenarios respectively as follows:

1. Add mockito-inline and use Mockito.mockStatic as an alternative.
2. Simply mocking some special static classes with Mockito.mockStatic will cause Static Initialization Error. For these special cases, we need to refactor the origin class with some tricks to decouple the usage of static method.
3. Change private method to protected

For examples, see: #11588
