JUnit Question: Download JUnit PDF

Compiling a JUnit test class is like compiling any other Java classes. The only thing you need watch out is that the JUnit JAR file must be included in the classpath. For example, to compile the test class HelloTest.java described previously, you should do this:

javac -cp junit-4.4.jar HelloTest.java

dir HelloTest.*
453 HelloTest.class
183 HelloTest.java

The compilation is ok, if you see the HelloTest.class file.
