title: Let Bundler Handle Autotest
To let Bundler{:rel="nofollow noopener noreferrer"} handle
Minitest-autotest{:rel="nofollow noopener noreferrer"} just make
sure to include gem minitest-autotest
in the Gemfile. This will put the gem
and its dependencies on the load path. That gets rid of the
invalid option: --server
exception you see otherwise.
