test: fix all_functional tests

[ST-DDT]

The all_functional.spec.ts doesn't work as expected. We need to fix this eventually.
This conceals 20 errors:

We have to check how we fix these issues.
Some fixes require changes to the definitions, other require changes to the code itself.

The fake() test works as expected I just improved/narrowed the check.
