Hema: This separate suite was created after consulting with Magnus, Lars,
Also long back I sent an email to everyone asking suggestion about the same.

There was a plan to move all the tests to backup suite, so Magnus said that
there is no need to run all the
backup tests with different character sets combinations. That's the reason
to create separate backup_charsets after taking advice from him.

Hema: No, you are correct. Actually I splitted some of the test cases in to
separate tests to have good coverage.
Also I thought that there is no specific test in backup that tests all
datatypes and all partitions alone, so I created separate tests. This will
help in running all datatypes/partitions with different combinations of
character sets/collations/storage engines. This way we can have good test

Hema: As far as testing of objects is concerned, WL#4222(Test of metadata
consistency) tests all the objects. Chuck is reviewing the tests for this WL
currently. Once I get approval to push from him, I will have to make slight
modifications to the test so that the same test can be run for different
combinations of csets and coll. I will let you know what modifications I am
going to make once I do it. There are some tests are common for different
There is no much difference between tests 2-4. I will modify the WL

Please let me know if you have any questions further.
