 * This test does the following:
 * 1) acquires the game-data path
 * 2) In the game-data dir, there are three files: testbed, TeStBeD and TESTBED
 * The former two are directories while the latter is a text file used for game engine detection
 *
 * Both the directories contain the file testbed.conf each which has a message written in it.
 * The code accesses the appropriate file using the fileSystem API, creates a read stream of it and
 * compares the message contained in it, with what it expects.
