overview
In short, the mock test environment is to prepare the product for actual use. This is achieved by gaining as much test experience and performance data as possible early in the product lifecycle.
A classic example involves testing components of a satellite. Components used in satellites cycle between extreme temperatures several times every 24 hours. When components are in direct sunlight, they can reach temperatures as high as 120°C. When they are in the shade, they can cool down to temperatures of -100C. A satellite that orbits the Earth about 14 times a day will, over its lifetime, experience over 50,000 thermal cycles between these extremes! Cycling between extremes tends to change material properties and wear down equipment prematurely.
The solar panels that power the satellites are made of multiple layers of material that are exposed directly to sunlight. directly affected by thermal stress. This means that the lifespan of any given satellite is directly dependent on how long the solar panels last during service. The longer the useful life of a satellite, the more cost-effective its operation will be.
