public class TestEngine

extends java.lang.Object

TestEngine holds ALL the the questions for a session. It reads the input file at testURL, and while inStream is not null, uses a StringTokenizer to read the file. It then creates a new question URL from testURL plus txt read from inStream (relative URL construction). It then creates a new answer URL from testURL plus txt read from inStream (relative URL construction). It then creates a new TestItem and adds it to the Vector testVector. Test vector is then cloned to currVector to prevent a concurrent access exception. The cloned Vector currVector is then randomised to ensure options are presented in different order each time.
