"""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 future, they should try to follow the same convention and not
|
|
make assumptions about execution order.
