Maybe replace the test with:

_original = [1, 2, 3];
_result = [_original] call CBA_fnc_shuffle;
TEST_OP(count _result,==,1,_fn);

[commy2]

If I understand everything correctly, then the original test fails with params expected types script error:

[1, 2, 3] params [["_array", [], [[]]], ["_inPlace", false, [false]]];

converts the 1 to [], and the 2 to false, and drops the 3.
Shuffling the empty array returns an empty array.
The empty array has count 0, which is different from the asserted 1.

This may have broken when adding params to the whole lib. I like the current way it works though, so we should keep the function as is since the change is about 5 years old at least.

That's my quick analysis of it as well.

The suggested replacement test seems more or less like the remaining first test, assuming you want 3 as expected count.

Ah, I missed that. Could just replace the assert line with

 TEST_OP(_result,isEqualTo,[],_fn);

Sure, will do
