Kristian Waagan updated DERBY-2646:
-----------------------------------
Attachment: derby-2646-05a-tests.stat
derby-2646-05a-tests.diff
'derby-2646-05a-tests.diff' contains a series of tests for Clob.
More tests can/should be added, they are far from complete.
There is one "normal" test, 'jdbcapi/ClobTest'. It is not enabled in any suite
yet, as two of the tests fails with the current implementation due to
UTFDataFormatException (which again is due to positioning/boundary errors).
They will be enabled as part of the next patch for this issue.
There is also four package-private test classes, all based off the abstract
superclass 'InternalClobTest'.
The test classes test the following cases:
SmallStoreStreamTest: Small read-only Clobs from a store stream
BiggerStoreStreamTest: Bigger read-only Clobs from a store stream, size
should cause crossing of various buffer sizes and boundaries.
SmallTemporaryClobTest: Temorary read-write Clobs held in memory.
BiggerTemporaryClobTest: Temporary read-write Clobs stored on disk due to
their size.
Transition from read-only to read-write is not tested in the package-private
tests, as transition is the responsibility of EmbedClob. I also considered
adding encryption to BiggerTemporaryClobTest, but decided to put this on hold
and address it in a later patch. I think we have some performance issues with
encrypted Clobs, but it can be due to the test implementation and should be
determined before any conclusions are taken.
The required framework for package-private tests are not in place. I will
possibly address this later, but for now the package private tests must be
compiled and run manually.
The simplest is to issue for instance this javac command from trunk after
having compiled Derby the normal way:
javac -d classes/ -classpath classes/:tools/java/junit.jar
java/testing/org/apache/derby/impl/jdbc/*java
Then run them with 'classes/' in the classpath:
java junit.textui.TestRunner org.apache.derby.impl.jdbc._Suite
