[BevapDin]

The code to test all mods just builds a list of the mods, and the test program simply loads them in the given order. Neither of them adds the "dda" mod, which is used to load the core game data.

This means the core game data (the skills etc.) isn't loaded at all, only the mods are loaded.

And the magic "module" checks the validness of the input (the skill ids) when it loads them. They don't exist because they have not been loaded because the core mod has not been loaded. Note: checking ids for validness should be done after everything has been loaded from JSON, as otherwise it requires that JSON is loaded in a specific order (in this case: skills before enchantments).
