Method Detail

test_setReleaseTime

public void test_setReleaseTime()

Unit tests verifies that the head of the commit time index is truncated when the release time is advanced and that it is still possible to obtain a read-only tx as of the timestamp immediately after the current release time.

test_snapshotCommitIndex

public void test_snapshotCommitIndex()

Unit test of the ability to snapshot the commit index. The test setups up the expected state of the commit index, verifies that state, shuts down the service, and verifies that a snapshot was written during shutdown. The test then restarts the service, and verifies that the commit index has the expected values (read from the snapshot). Another entry is then added to the commit index and the release time is advanced, which should cause the head of the commit index to be truncated. The test then verifies the expected state of the commit index, shuts down the service, and verifies that another snapshot file was written. Finally, we restart the service one more time and verify that the commit index has the data that we would expect if it had read the 2nd snapshot.
