Method Summary

void	testConcurrentWrites() Attempts to test Log's behavior when called concurrently from several sources.
void	testExceptionPrinting() Tests the Exception printing methods in the Log file by throwing two exceptions and using the two types of log methods (one with the Throwable itself and the other with the the StackTraceElement[])
void	testLog() Adds a couple of generic messages to a log, and then tests to make sure they are all correct, in the correct order, and their timestamps are within the past few seconds.

Method Detail

testLog

public void testLog()
             throws IOException

Adds a couple of generic messages to a log, and then tests to make sure they are all correct, in the correct order, and their timestamps are within the past few seconds.

Throws:

IOException

testExceptionPrinting

public void testExceptionPrinting()
                           throws IOException

Tests the Exception printing methods in the Log file by throwing two exceptions and using the two types of log methods (one with the Throwable itself and the other with the the StackTraceElement[])

Throws:

IOException

testConcurrentWrites

public void testConcurrentWrites()
                          throws IOException,
                                 InterruptedException

Attempts to test Log's behavior when called concurrently from several sources. Spawns NUM_THREADS LogTestThreads (see above)that wait a random number between 0 and DELAY milliseconds and then log a message. The function tests to make sure that the messages and dates are all intact (if the Log was not handling concurrent requests properly, the entries in the log may be corrupted).

Throws:

IOException

InterruptedException
