Tried this first, but is unmaintained: https://github.com/sakari/robot-mode

Borrowed robot-font-lock-keywords from sakari/robot-mode and combined with test runner shortcuts similar to https://github.com/dougm/bats-mode and https://github.com/nlamirault/gotest.el
