Andrey Petrov 46ec63b849 ethdb/dbtest: addd test suite for ethdb backends (#19960) ... - Move the existing tests from memorydb into a generalized testsuite that can be run by any ethdb backend implementation. - Add several more test cases to clarify some non-obvious nuances when implementing a custom ethdb backend, such as the behaviour of NewIteratorWithPrefix vs NewIteratorWithStart. - Add leveldb to the testsuite using in-memory storage for fast execution.		2019-08-22 11:47:24 +02:00
