I tried this out on my mac:

➜  ~ bitcoin-cli backupwallet ./

No error or anything. It seems to have locked up bitcoind:

➜  ~ bitcoin-cli help
error: Could not locate RPC credentials. No authentication cookie could be found, and no rpcpassword is set in the configuration file (/Users/shammah/Library/Application Support/Bitcoin/bitcoin.conf)
➜  ~ bitcoind
Error: Cannot obtain a lock on data directory /Users/shammah/Library/Application Support/Bitcoin. Bitcoin ABC is probably already running.

OTOH, my coins are still in my wallet after killing everything off and restarting it. :)

Could you investigate a bit more?

Do you still have said conf file with credentials?
What if you pass the explicit path "/Users/shammah/Library/Application Support/Bitcoin/" to backupwallet?

Cleanup test to use assert_raises_jsonrpc

207	this is linux/unix specific, dunno if we are try to run these tests on win on other OS but I wonder that using `os.path.join` can make no harm

I tested this again today with bitcoind running in the data directory, and got the following (good error):

➜  ~ bitcoin-cli backupwallet ./
error code: -4
error message:
Error: Wallet backup failed!

We may want to disallow relative paths due to the way the cli works with the daemon though. However, that'd be better as another ticket.

Thanks for making these changes!

207	Good call.

207	Forward slash works fine on Windows and is currently used everywhere in rpc-tests.

I don't think I meant to "done" the comment in code. I just meant to comment on it; have to get used to the interface...

qa/rpc-tests/walletbackup.py
207	Didn't know that `/` works on Windows. I erroneously extended the fact that command prompt doesn't accept `/` as path separator to all kind of access. Apparently has been accepted since MS-DOS DOS 2.0 and up. Guess this is the reason why it is used across all the tests then.
