Nothingness is the state of non-existence;the condition of being nothing.
I am not sure on how you can test on nothingness.
In computing, “nothing” can be a keyword (in VB.Net) used in place of something unassigned, a data abstraction. Although a computer’s storage hardware always contains numbers, “nothing” symbolizes a number skipped by the system when the programmer desires. Many systems have similar capabilities but different keywords, such as “null” (e.g. SQL), “NUL”, “nil”, and “None” (Python).
To instruct a computer processor to do nothing, a keyword such as “NOP” may be available. This is a control abstraction; a processor that executes NOP will behave identically to a processor that does not process this directive.
