Concept testing, test marketing and product testing are parts of New Product Development.
Concept testing is the process of using surveys (and sometimes qualitative methods) to evaluate consumer acceptance of a new product idea prior to the introduction of a product to the market.
Test marketing is an experiment conducted in a field laboratory (the test market) comprising of actual stores and real-life buying situations, without the buyers knowing they are participating in an evaluation exercise. It simulates the eventual market-mix to ascertain consumer reaction for a new product.
Product testing, also called consumer testing or comparative testing, is a process of measuring the properties or performance of products. It is usually used for new products.
