I'd suggest looking at: * https://pkg.go.dev/github.com/rogpeppe/go-internal/testscript?tab=doc for the CLI testing aspect * https://pkg.go.dev/mvdan.cc/dockexec?tab=overview for the isolation piece There are lots of examples of where testscript is being used: https://github.com/rogpeppe/go-internal/wiki/Users-of-testscript govim is one such an example where we also provide an example of how to run those tests via dockexec: https://github.com/govim/govim/wiki/govim-tests#running-tests---using-cmdgo In our case it's not so much for isolation, rather providing dependencies. The #tools channel on slack (or mailing list https://groups.google.com/forum/#!forum/golang-tools) is also a good place to chat about this more in case you had any follow-ups.
