I have to perform a 'stress test' on Amazon, Inc.

The section specifically states:

"Financing plans typically work well if the assumptions on which they are based turn out to be accurate. However, this is an insufficient test in situations marked by volatile and unpredictable conditions. The test of the soundness of a 3-5 year plan is whether the continuity of the flow of funds to all strategically important programs can be maintained under various scenarios of adversity for the firm and/or the capital marketsor at least be maintained as well as your competitors are able to maintain the funding of their programs."

Is there a stress-test process that I can follow to analyze Amazon? What would be the best path forward?
