The really funny bit is that the classic visual programming tool LabView is designed mostly for test automation. But it ends up practically requiring the creation of unmaintainable spaghetti (this[1] being a classic example) and there's no test automation possible for it. It's a test automation platform so complex it needs (but doesn't have) test automation for its automation of your tests.

No one should ever write code like that and no experienced LabVIEW developer would find that anywhere close to acceptable. And there are no doubt analogs in the text-based world, except you may not even know it because the structure isn’t as visible.

Also, there are certainly test frameworks for testing LabVIEW code. NI has a few but then JKI, a third party company, has multiple testing frameworks including Caraya, which is similar in philosophy to something like FsUnit for F# or Elixir’s ExUnit.
