fix(docs): hide godoc for changes follower test fixtures

[mojito317]

PR summary

Previously there were leaked out parts from test fixtures in our published documentation. Excluding test files can happen with adding _test postfix to the filename.

I used go doc --all -u features on our main and this branch and exported the diff into this file:
features.diff.txt

But I leave here the diff under this toggle too.
