Regarding testing techniques in the field of space research

mmmmmmmmmm, really a different !!!!!!!!!! see we can test operations on different temprature conditions,and we can test it in minus gravitational force. We can test it further by giving different virus(!!) to it. Virus means infected programs that may cause severe damage,atleast there will be such chance in some % atleast.We can do adhoc testing 2 test operation so that we get to know,how they work in chaotic condiotions.By giving stress we can get to know the exactly that what system do exactly??
