testBasicScenario

public void testBasicScenario()
                       throws java.lang.Exception

Make sure that deleted rows are retained. Family delete markers are deleted. Column Delete markers are versioned Time range scan of deleted rows are possible

Throws:

java.lang.Exception

testRawScanWithoutKeepingDeletes

public void testRawScanWithoutKeepingDeletes()
                                      throws java.lang.Exception

Even when the store does not keep deletes a "raw" scan will return everything it can find (unless discarding cells is guaranteed to have no effect). Assuming this the desired behavior. Could also disallow "raw" scanning if the store does not have KEEP_DELETED_CELLS enabled. (can be changed easily)

Throws:

java.lang.Exception
