To use, create a class that implements get_tests(), and pass it in

as the test generator to TestManager. get_tests() should be a python
|

generator that returns TestInstance objects. See below for definition.

TestNode behaves as follows:
|

Configure with a BlockStore and TxStore
|
||||
on_inv: log the message but don't request
|
||||
on_headers: log the chain tip
|
||||
on_pong: update ping response map (for synchronization)
|
||||
on_getheaders: provide headers via BlockStore
|
||||
on_getdata: provide blocks via BlockStore
