Previously this was tested as a white box. Database access methods were
duplicated as test code and compared to the return value of the code
under test. This approaches leads to brittle test because it relies
heavily on implementation details. This commit changes this and prepares
for additional test coverage being added in later commits.
The channeldb implements the persistent storage engine for lnd and
generically a data storage layer for the required state within the Lightning
Network. The backing storage engine is
boltdb, an embedded pure-go key-value store
based off of LMDB.
The package implements an object-oriented storage model with queries and
mutations flowing through a particular object instance rather than the database
itself. The storage implemented by the objects includes: open channels, past
commitment revocation states, the channel graph which includes authenticated
node and channel announcements, outgoing payments, and invoices
