Is there anything stopping an employer from pretesting you to avoid adding a potentially expensive employee to their roster?

Generally it runs aground with things like the ADA because you can't just "accidentally" find out the person has a covered condition, you're just never allowed to ask or require it be told. Exceptions for something like an airline pilot on matters related to the job like sight notwithstanding. This is why you always see things like "can lift up to 40 lbs" type requirements instead.
