Overall this changes look good to me, thanks for the feature @Samuelopez-ansys

None the less, I would like to discuss two points:

1. Should we use casefold() here instead of lower() ? I discovered this method in FIX: Fixes to get_object_material_properties method #5626 and it seems to be designed specifically for case-insensitive comparisons. This would allow users use special cases in certain languages or alphabets. However, we might not want to allow that :D
2. Instead of adding a new file to the pyaedt repo, and since the JSON data is tiny, could we avoid adding the JSON file and create it on the fly while testing ? For example, at the begining of the file we could have a constant with the JSON file content and in the test's setup, we could create the file with json.dumps(...) ?

I marked this review as request changes but it's more to ensure that a discussion occurs than a real need for changes :)

@SMoraisAnsys I applied the casefold, I like it, and also I removed the JSON files in the test, and it creates them on the fly

LGTM, nice to discover the use of the object request in pytest !
