This function creates a "while loop" in the participant's testing session. This "while loop" corresponds to the following procedure:
Check whether a condition (termed test) is satisfied.
If the condition is satisfied,
execute a series of test elements (termed logic),
otherwise exit the while loop.
Loop back to step 1.
