1. Computer models and simulations allow for virtual testing based on computer models without the risks of physical testing. 2. Reduced-scale testing uses scale models in controlled environments like wind tunnels to gather data in a cost-effective way before full-scale testing. 3. Full-scale testing is needed to validate data from other tests by trying a full prototype in real-world conditions to ensure everything works as intended outside.
