Answer:

Product testing, also called consumer testing or comparative testing, is a process of measuring the properties or performance of products. The theory is that since the advent of mass production manufacturers produce branded products which they assert and advertise to be identical within some technical standard.

Before allowing any product to go on sale, it must be proven that it is completely safe. For example, product testing can prove that household tools or appliances are safe for use, or find any defects that could potentially be unsafe before the products are available for sale.

Catch product defects early on.

To avoid any issues with customer dissatisfaction or product malfunction, testing before use is crucial. ... To protect users, your company reputation and integrity, it is important to minimize the risk of defects by thoroughly testing products before they are sold.
