Evolving the Cloud Foundry CLI UX

on YouTube ↗35m

" summary

Cloud Foundry’s cf CLI reports 1.8 million downloads and moves from tangled Go code into a three-layer refactor (display, business, API) that wraps errors in contextual middleware, stops opening a new connection per API call, and cuts repeated file copying on push. The team generates test doubles with counterfeiter fakes, ships faster commands, and documents behavior with characterization tests; result is noticeably faster, more consistent output and 700+ integration tests plus roughly 1,500 unit tests.
