Description: Product testing evaluates the quality and performance of a product before its launch. This process is fundamental in the software development lifecycle and in the manufacturing of physical products, as it ensures that the product meets quality standards and satisfies end-user expectations. Product testing can include a variety of methods, such as functional testing, performance testing, usability testing, and security testing. Each of these methods focuses on different aspects of the product, allowing for the identification and correction of errors or deficiencies before the product reaches the market. Implementing product testing not only helps improve product quality but can also reduce long-term costs by avoiding the release of defective products that could result in returns or damage to brand reputation. In an increasingly competitive business environment, product testing has become an essential practice to ensure customer satisfaction and the commercial viability of the product.
