@Transactional does not remove DB records after unit test method done

[yongqxu]

I am using SB2.1.7 with JDK11 and embedded MySQL 5.7.19, i noticed that even my test method has @transactional, I still have to explicitly remove all records before each test in @before method, otherwise tests will interfere each other. did i miss any configuration? The test method remove records after the test in H2 before.
