"""Test the bumpfee RPC.

Verifies that the bumpfee RPC creates replacement transactions successfully when
|
||||
its preconditions are met, and returns appropriate errors in other cases.
|

|
||||
This module consists of around a dozen individual test cases implemented in the
|
||||
top-level functions named as test_<test_case_description>. The test functions
|
||||
can be disabled or reordered if needed for debugging. If new test cases are
|
||||
added in the the future, they should try to follow the same convention and not
|
||||
make assumptions about execution order.
