In order to include the "__metadata" object in your POST, you need to specify your content-type as "application/json;odata=verbose".

Alternatively, if you need to use the "application/json;odata=minimalmetadata" content-type, remove the whole "__metadata" json object, and instead specify the "ContentTypeId" in your body just like you are doing for your "Title", but you would need to first look up the ID of your TestListListItem ContentType.
