I don't think it matters much if this is inline or in separate file. If you want to test your tests, "yq -r .run input.yaml | sh -e" works as well. In fact, if I really wanted to test my tests, I'd say that directly testing the corresponding clause is the more comprehensive approach. For example, what if someone accidentally changes the line to read: run=/path/to/install-scriptq ? then your test of "install-script" will not catch anything. But if your test runs "yq -r .run | sh -e", then it will catch that error. And you can still forward to a script if you wanted to. So let's keep inline scripts, they are very reasonable methods for just a few commands.
