Java Model Solution

HelloWorld.java:

package de.proglabor.aufgabe1; public class HelloWorld { public static String greet() { return "Hello World!"; } public static void main(String[] args) { System.out.println(greet()); } }

JUnit 4 Test

package de.proglabor.aufgabe1; import junit.framework.TestCase; public class HelloWorldTest extends TestCase { public void testHello() { HelloWorld h = new HelloWorld(); assertEquals(h.greet(), "Hello World!"); } }

Note that if the source code belongs to a package (i.e. contains a package statement) the filename and the test class name must contain this package name. Otherwise the test will not compile.

Filename:

de/proglabor/aufgabe1/HelloWorldTest.java

Test Class :

de.proglabor.aufgabe1.HelloWorldTest

Checkstyle: checking that some string does not occur

This can be used for any file in any programming language. Property "format" contains the string which should at most "maximum" times occur.
