One of the world’s great cities, New York City (known as “The Big Apple”, “NYC,” or just “New York”) is a global center for media, entertainment, art, fashion, research, finance, and trade. The bustling, cosmopolitan heart of the 4th largest metropolis in the world and by far the most populous city in the United States, New York has long been a key entry point and a defining city for the nation. From the Statue of Liberty in the harbor to the Empire State Building towering over the Manhattan skyline, from the tunnels of the subway to the skyscrapers of Wall Street, from the bright signs of Times Square to the naturalistic beauty of Central Park, and from Yankee Stadium in the Bronx to Coney Island in Brooklyn, New York’s landmarks are quintessential American landmarks.

Sobering but true: it's impossible to thoroughly test an IT system of any real size. Roger S. Pressman pointed out in his book Software Engineering, one of the classic texts in the field, that "exhaustive testing presents certain logistical problems....Even a small 100-line program with some nested paths and a single loop executing less than twenty times may require 10 to the power of 14 possible paths to be executed." To test all of those 100 trillion paths, he noted, assuming each could be evaluated in a millisecond, would take 3170 years.
