Here are three JUnit classes to do unit testing on Project 3 classes WordNode, WordList, and HashList.

To use these classes, download them to your Project 3 source directory and launch them as JUnit test classes.

For example, from the command line on Lore (or the MC cluster), you can use the javat command located in the /homes/cs190m/student_bin directory (which should be in your path). The javat command is just a short shell script that sets the CLASSPATH environment variable, compiles the given test class, and uses the JUnit TestRunner class to run it:

#!/bin/sh
CLASSPATH=".:/homes/cs190m/lib/junit-4.5.jar"; export CLASSPATH
javac $1.java
java junit.textui.TestRunner $1

To run these three tests, you would type (at the UNIX command line prompt):

javat WordNodeTest
javat WordListTest
javat HashListTest

These three test cases work (report no errors) on my version of Project 3, but I may have made some assumptions that you didn't. If you have questions, a suggestion, or find a mistake in this process, please send me email.
