* 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)

(If a test case is A(B(x)), where A is implemented as C(D(x)), then A is //directly called at top level//, B is //directly called at non-top level//, and C and D are //indirectly called//.
| URI percent decode (URI percent encode (馃)) as a test of | Type | Currently | Expected |
|-----|-----|-----|-----|
|URI percent decode| directly called at top level |will work| will work|
|URI percent encode| directly called at non-top level |will not work| will work|
|Other function not mentioned| not directly called |will not work| will show a proper error message(*) |
(*): It may be possible that a tested function is only indirectly called, 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).
