 Use a [[http://www.junit.org|JUnit]] test case.  JUnit is a Java package that facilitates "unit testing": creation, execution, and evaluation of repeatable tests on your code.  It is designed to support incremental testing ([[http://en.wikipedia.org/wiki/Test-driven_development|test-driven development]]), but can also be used in a variety of ways including "whole program" testing.   Use a [[http://www.junit.org|JUnit]] test case.  JUnit is a Java package that facilitates "unit testing": creation, execution, and evaluation of repeatable tests on your code.  It is designed to support incremental testing ([[http://en.wikipedia.org/wiki/Test-driven_development|test-driven development]]), but can also be used in a variety of ways including "whole program" testing.

 For projects that take input from the command line (or redirected from a file) and produce gradable results to standard out, automated testing requires that these streams be redirected in the JUnit test class.  This section explains how to do that. For projects that take input from the command line (or redirected from a file) and produce gradable results to standard out, automated testing requires that these streams be redirected in the JUnit test class.  This section explains how to do that.
