void verifyConcurrentExecution ( )

Test:

verify the thread function is actually performed concurrently

• use a derived Thread object, also holding a local data field
• the thread function sleeps, and then stores the sum of two numbers
• demonstrate that each instance can have a different argument binding
• verify each thread function has actually been invoked once per thread, by comparing a local sum with values collected from the Thread objects,
• moreover measure the overall time required for launching the threads and then waiting for all threads to have terminated and detached; this time must be shorter than all the average sleep times compounded (as if the function was invoked sequentially).
