Description

« Hide

The in-memory back end should be tested as part of the standard regression tests.

The following is a good start:
o simple create / boot test
o create in-memory db, backup, restore with default storage engine, modify, restore with createFrom into memory again
o add the functional test(s) written by Cheng
o more unit tests

On a longer term, we should consider to add the possibility to run all or a subset of the general regression tests with the in-memory back end.

ASF	#753210	Fri Mar 13 11:33:11 UTC 2009	kristwaa	DERYB-4085: Improve testing of the in-memory back end. Added the first basic tests for the in-memory back end. One test just tries to connect to a non-existing database with the memory protocol. The other creates a in-memory database, adds a table, creates a backup, adds another row with the default storage engine (directory) and finally recreates a in-memory database and reads all rows from the table. The tests are not enabled as part of any larger suite yet. Patch file: ~~DERBY-4085~~-1b-basic_tests.diff

ASF	#759181	Fri Mar 27 15:45:59 UTC 2009	kristwaa	~~DERBY-4085~~: Improve testing of the in-memory back end. Adds a functional test (mixture-of-Gaussian distribution). The calculations are carried out both in Java and though SQL, then compared. The tests are not yet compatible with JSR 169 / JavaME. Patch contributed by Cheng Che Chen (chatom).
