[infinispan-issues] [Red Hat JIRA] (ISPN-12037) JUnit-friendly replacement for MultipleCacheManagerTest

JUnit-friendly replacement for MultipleCacheManagerTest ------------------------------------------------------- Key: ISPN-12037 URL: https://issues.redhat.com/browse/ISPN-12037 Project: Infinispan Issue Type: Task Components: Core, Test Suite Affects Versions: 11.0.0.Final Reporter: Dan Berindei Assignee: Dan Berindei Priority: Major Fix For: 12.1.0.Final Core tests that need one more more cache managers extend either {{SingleCacheManagerTest}} or {{MultipleCacheManagersTest}}. Many other modules' tests do the same for convenience. We would like to eventually move all modules to JUnit, and having an alternative to MCMT that can be used from either JUnit or TestNG and can support an incremental migration is the first step. The starting plan is for a {{TestCluster}} class for building and interacting with clusters including features from MCMT/TestingUtil/TestCacheManagerFactory/BasePartitionHandlingTest. Assertions like {{assertLocked()}}, {{assertIsInL1()}} etc. would be in separate classes, ideally with AssertJ-like {{assertThat}} static methods.
