Unit Testing

2. Unit
 Perangkat Lunak
 Code
 Documentation
 Procedure
 Data
 Satuan terkecil Code
 Unit
 Method atau Function atau Procedure

3. Unit Test
 a piece of code
 written by a developer
 executes a specific functionality in the code under test
 Unit tests ensure
 that code is working as intended
 and validate that this is still the case after code changes.
 Menguji apakah Unit sudah berfungsi sebagaimana yang
diharapkan (as expected)
 Menguji Unit secara independen, tanpa bergantung pada
hasil komputasi Unit lain

4. Rehat Sejenak: JUnit
 Package untuk menjalankan Unit Testing di Java

 Update CLASSPATH environment variable
 Set CLASSPATH=.;C:jarfilesjunit-4.10.jar
 Export CLASSPATH=.:/usr/share/java/junit-4.10.jar

5. Deklarasi Class Test Case
import junit.framework.*;
public class MaxThreeTest extends TestCase {
public MaxThreeTest(String name) {
super(name);
}
@Test public void testSimple() {
assertEquals(9, MaxThree.largest(7, 8, 9));
}
}

6. Kompilasi Class Test Case
 CLASSPATH sudah diset
 javac MaxThreeTest.java
