The ability to test a product concept digitally before prototyping is possible by using:

Concept testing using digital 3D prototype

Explanation:

By creating the product prototype in 3D form, the people who create the product could make a prediction on whether the product design has high likelihood of success.

Companies in recent years start to do this before making an actual prototype since it cost a lot less and can be done faster compared to making an actual prototype.

That being said, the conclusion that created from digital 3D prototype is not 100% reliable. There might be a couple of problems that could only occur after the prototype is made in a physical form.  In business, success in digital 3D prototype is used as a presentation to secure another funding to make actual prototype.
