Test suite should be able to log to file too, without losing colors on the terminal
Originally created by @intrigeri on #8894 (Redmine)
By default the test suite logs to the terminal, with fancy colors. Fine.
I can also duplicate the output with tee
so that I get a log file.
However, if I do that, then I lose the nice colors and the output is
harder to read. Dear test suite folks, how hard would it be to add a
--log-file FILE
option that sends a copy of the output to a file,
without losing the fancy colored output on the terminal?
