* Go to a function e.g. https://www.wikifunctions.org/view/en/Z10119
* Create a test that does not involve the function connected, e.g. https://www.wikifunctions.org/view/en/Z10511
Expected: Showing an error such as "The test does not involve the connected function".
Actual: Fails with `{"Z1K1":"Z5","Z5K1":"Z507","Z5K2":{"Z1K1":{"Z1K1":"Z7","Z7K1":"Z885","Z885K1":"Z507"},"Z507K1":"Could not find argument Z10119K1."}}` (even if the test will succeed if connected with Z10000)

(*): It may be possible that a tested function is only indirectly called (for example A(B(x)) where A(x)=C(D(x))), but determining this is out of scope of this task (and it not well determined since one function may have multiple implementions and only some of which use a specific function).
