[Lldb-commits] [PATCH] D85107: Add a test for 'b' (toggle breakpoint)

[Luboš Luňák via Phabricator via lldb-commits]

llunak created this revision.
llunak added a reviewer: clayborg.
llunak requested review of this revision.

The test needs the python curses module, to get the proper escape sequence to send the down key event.
I'm not sure if it's ok to just use the module, or if some check for it should be added too.
