What is the biggest expectation when engineers test out designs?

The biggest expectation of an engineer when he tests out a new design is that he expects the product to not fail, and all the stress and strains does not exceed the failure criteria.

Explanation:

In engineering design, failure of materials is considered, and the designed is usually designed to not reach or exceed the failure region of its stress strain relationship. This is why factor of safety is usually determined for each material, and it serves as a guideline for the designing of new designs. This factor of safety is the value, below which the material properties is able to cope with design stress and strain, and above which failure is likely to occur.
