The run method takes the name of a binary to run, the arguments to that binary and some options:
:command_path -> A $PATH-like variable that defines where to look for the binary
on the filesystem. Colon-separated, just like $PATH.
:expected_outcodes -> An array of integers that defines the expected exit codes
of the binary. Defaults to [0].
:log_command -> Log the command being run when set to true (defaults to false).
This will only log if logging in general is set to true as well.
:swallow_stderr -> Set to true if you don't care what happens on STDERR.
