Curl and jq are plenty to get the job done. As the author points out, you can capture all your curl commands in scripts and then orchestrate with other scripts for testing purposes. On top of all the benefits the author has already mentioned, you get a boost if you're doing your development work in a VM, as I do. It's less you have to install, configure, and manage. Sure, that can be automated, but it's just more stuff you have to take care of and the longer you have to wait for a fresh VM to be ready.
