Answer:
Simulated test markets.
Step-by-step explanation:
During the market testing stage of the new-product process, a product may be tested multiple times with consumers to get their reactions with test marketing, one type of which is known as simulated test markets.
A simulated test market can be defined as a marketing research technique that involves the exposure of consumers to an unreal market in order to observe their reactions to a new product. It involves advertising in stages through a simulated market so as to determine a customer's purchase decision, forecast demand and market analysis for a new product.
Hence, a simulated test market is aimed at observing and analyzing potential customer's reaction to a new product before it's introduced to the market.
