The output would produce arbitrary number of decimal points, sometimes resulting in 9 decimals:
AssertionError: Fee of 0.00000415 BTC too low! (Should be 0.000006175 BTC)
The above looks like the expected fee is 6175 sats when in reality it's 618.

Also warn if bitcoind is configured to use a relative -datadir path.
Specifying paths relative to the current working directory in a daemon process
can be dangerous, because files can fail to be located even if the
configuration doesn't change, but the daemon is started up differently.
Specifying a relative -datadir now adds a warning to the debug log. It would
not be backwards-compatible to forbid relative -datadir paths entirely, and it
could also be also inconvenient for command line testing.
Specifying a relative -walletdir now results in a startup error. But since the
-walletdir option is new in 0.16.0, there should be no compatibility issues.
Another reason not to use working directory paths for -walletdir specifically
is that the default -walletdir is a "wallets" subdirectory inside the datadir,
so it could be surprising that setting -walletdir manually would choose a
directory rooted in a completely different location.
test_framework accepts a new --usecli parameter. Running the test with
this parameter will cause all RPCs to be sent through bitcoin-cli rather
than directly over http. By default, individual test cases do not
support --usecli, and self.supports_cli must be set to True in the
set_test_params method.
We can make supports_cli default to True in future once we know which
tests will fail with use_cli.
Change TestNodeCLI.__call__() to return a new instance instead of modifying the
existing instance. This way, it's possible to create different cli objects that
have their own options (for example -rpcwallet options to connect to different
wallets), and options set for a single call (`node.cli(options).method(args)`)
will no longer leak into future calls.
Add network thread_start(), network_thread_running() and
network_thread_join() utility functions in mininode.py and use
network_thread_running() in network thread assertions.
This commit moves the logic that sends a version message
on connection from NodeConn to NodeConnCB. NodeConn should
not be aware of the semantics or meaning of the P2P payloads.
This makes NodeConnCB a subclass of NodeConn, and
removes the need for the client code to know
anything about the implementation details of NodeConnCB.
NodeConn can now be swapped out for any other implementation
of a low-level connection without changing client code.
The mininode module includes code to support p2p versions below
60001. However, the test_framework does not support versions
of Bitcoin Core before V0.13.0. Remove code supporting
p2p versions before 60001 (which has never been run).
BIP31 support was added to Bitcoin Core in version 0.6.1. Our test
framework is incompatible with Bitcoin Core versions that old, so remove
all special logic for handling pre-BIP31 pings.
p2p connections can now be added to TestNode instances.
This commit also updates the example test to use the new
p2p interface in TestNode to demonstrate usage.
A future commit will update the existing tests to use p2p through the
TestNode.
This should fix issues with the multiwallet test and symlinks
when the tmpdir is a relative path.
Rather than fixing os.symlink to work with paths relative to a
directory descriptor, which does not work on Windows, normalize
the path instead.
