Stress testing along the way would only show a complete failure of the system.
The preparation of a genetic design is also reciprocal. For example, the tailorability of the Formid product to human anatomy permits the flattening of data acquired from the hardware (all seats are comparable in movement as bodies are normalized) so that the machine learning algorithm can compare data sets accross a wide variety of anatomical idiosyncracies with ease. As an interdependent design, none of these systems can be prepared without the other, and their interdependency necessitates the progress of the work to be simultaneous prior to a demonstration ready product.
Unfortunately, the evaluation of such a system while it is being designed is not as impressive unless you understand the process. Stress testing along the way would only show a complete failure of the system. For example, capital investment in a project will require proof of sales however a project that is large or complex enough may require external funding prior to such proof, leaving the project subject to stress testing and seemingly a total failure.
