Summary:
As we had the discussion some weeks ago. Java needs a test framework and should support code coverage analysis. This pull request includes:
Move Tests from main method functionality to Junit4
Move WriteBatchTest to test package
Adjust the Makefile to run Junit4
Download dependencies from Make (once if not-present)
Adjustment of the rocksjni.pom to run coverage analysis using jacoco
Javadoc excludes now tests
Two bugfixes regarding GC cleanup which came up within the test runs
Make can be used as beforehand to build and run RocksJava. make test runs tests using the command-line version of Junit4.
Maven can be used to retrieve code coverage reports using mvn -f rocksjni.pom package. Code coverage reports can then be found as usual in the site folder.
Testing libraries available within Java
Junit4 (incl. hamcrest-core dependency)
AssertJ (providing fluent syntax for assertions, cglib dependency)
Mockito to provide mocktests
Libraries as said before are not statically within this commit or filesystem instead they are downloaded using curl. Make checks if files are present, if so it will perform tests without downloading the libraries again.
Note: Libraries are only necessary to compile & run tests.
Next steps after merge:
Get the maven build into travis-ci and coveralls.io
Filling up the missing test spots (based on coverage data)
Test Plan:
make rocksdbjava
make jtest

Summary: Store links to live files in directory on same disk
Test Plan:
Take snapshot and open it. Added a test GetSnapshotLink in
db_test.

Summary:
This is just a simple test that passes two files though a compaction. It shows the framework so that people can continue building new compaction *unit* tests.
In the future we might want to move some Compaction* tests from DBTest here. For example, CompactBetweenSnapshot seems a good candidate.
Hopefully this test can be simpler when we mock out VersionSet.
Test Plan: this is a test

Summary:
Make db_stress built for ROCKSDB_LITE.
The test doesn't pass tough. It seg fault quickly. But I took a look and it doesn't seem to be related to lite version. Likely to be a bug inside RocksDB.

It seems that on some FS we get more blocks than we ask for. This is
already handled when checking the allocated number of blocks, but
after the file is closed it checks for an exact number of blocks,
which fails on my machine.
I changed the test to add one full page to the size, then calculate
the expected number of blocks and check if the actual number of blocks
is less or equal to that.
Summary: Add a unit test in db_test to verify the behavior when both of merge operator and compaction filter apply to a key when merging.
Test Plan: Run the new test

Summary: As a short-term fix, let's go back to previous way of calculating NeedsCompaction(). SIGSEGV happens because NeedsCompaction() can happen before super_version (and thus MutableCFOptions) is initialized.

Summary:
CorruptionTest for backupable_db_test did not call
GarbageCollect() after deleting a corrupt backup,
which sometimes lead to test failures as the newly created backup
would reuse the same backup ID and files and fail the consistency
check.
Moved around some of the test logic to ensure that GarbageCollect()
is called at the right time.
Test Plan:
Run backupable_db_test eight times and make sure
it passes repeatedly. Also run make check to make sure other
tests don't fail.

Summary:
Move NeedsCompaction() from VersionStorageInfo to CompactionPicker
to allow different compaction strategy to have their own way to
determine whether doing compaction is necessary.
When compaction style is set to kCompactionStyleNone, then
NeedsCompaction() will always return false.
Test Plan:
export ROCKSDB_TESTS=Compact
./db_test

Summary:
Improve the backup engine by not deleting the corrupted
backup when it is detected; instead leaving it to the client
to delete the corrupted backup.
Also add a BackupEngine::Open() call.
Test Plan:
Add check to CorruptionTest inside backupable_db_test
to check that the corrupt backups are not deleted. The previous
version of the code failed this test as backups were deleted,
but after the changes in this commit, this test passes.
Run make check to ensure that no other tests fail.
