Path error messages while executing test_bitcoin #15944

Compiled bitcoin-0.18.0.tar.gz from https://bitcoin.org/bin/bitcoin-core-0.18.0/ on Ubuntu 18.04.2 LTS (using this (simple) bash script). The compilation went well (had to add doxygen to suppress a warning message). When running the test: test_bitcoin in bitcoin-0.18.0/src/test/, I get the following error messages (multiple times):

Error: Specified -walletdir "/tmp/test_bitcoin/1556861148_943311758/tempdir/path_does_not_exist" does not exist

and

Error: Specified -walletdir "/tmp/test_bitcoin/1556861730_643733972/tempdir/not_a_directory.dat" is not a directory

and

Error: Specified -walletdir "wallets" is a relative path

Note that at the end it still says: *** No errors detected

I believe this is an InitError, which are logged to the debug.log as well as stdout (or stderr, I don't recall).

To avoid the error to appear you could maybe disconnect the ui slot temporarily?

@sumBTC The erroneous repetition of error messages was fixed in #15352 - after that you should only get one error message per error.

Regarding the other issue (the -walletdir errors): I agree that passing tests should be silent. This should be fixed :-)

Thanks for reporting!

FWIW, also noted here: #14430 (comment). These error messages are a source of confusion.

Fwiw, I'm seeing the same output (repeated does not exist, is not a directory, is a relative path) when running test_bitcoin from the binary release on archlinux.

@practicalswift

agree that passing tests should be silent.

that's indeed why I reported this :-), I don't think the errors are very serious but they are a bit "all over the screen". Thanks for the feedback!
