verbosity: Verbosity level to use
test_preserve_dirs: True to preserve the input directory used by tests

tests). If a single test is selected (in args[0]) it also preserves
the output directory for this test. Both directories are displayed
on the command line.
processes: Number of processes to use to run tests (None=same as #CPUs)
args: List of positional args provided to binman. This can hold a test
name to execute (as in 'binman test testSections', for example)
