How to write test cases using JUnit framework?

You want to write unit tests with JUnit.


4.2.2 Solution


Create a subclass of junit.framework.TestCase. Each unit test is represented by a


testXXX( ) method within the TestCase subclass.


4.2.3 Discussion


Example 4-1 shows an extremely simple test case. A test case is a subclass of TestCase and


contains a collection of unit tests. Instances of TestCase are sometimes referred to as test fixtures,


although we prefer to say ';test case'; since that matches the class name. Each unit test is a public, noargument


method beginning with ';test';. If you do not follow this naming convention, JUnit will not


be able to locate your test methods automatically. Instead, you would have to write a suite( )


method and construct instances of your test case, passing the test method name to the constructor.


Example 4-1. Simple test case


package com.oreilly.javaxp.common;


import junit.framework.TestCase;


/**


* Sample unit tests for the {@link Person} class.


*/


public class TestPerson extends TestCase {


/**


* This constructor is only required in JUnit 3.7 and


earlier.


* @param testMethodName the name of the test method to


execute.


*/


public TestPerson(String testMethodName) {


super(testMethodName);


}


/**


* A unit test to verify the name is formatted correctly.


*/


public void testGetFullName( ) {


Person p = new Person(';Aidan';, ';Burke';);


assertEquals(';Aidan Burke';, p.getFullName( ));


}


/**


* A unit test to verify that nulls are handled properly.


*/


public void testNullsInName( ) {


Person p = new Person(null, ';Burke';);


assertEquals(';? Burke';, p.getFullName( ));


// this code is only executed if the previous


assertEquals passed!


p = new Person(';Tanner';, null);


assertEquals(';Tanner ?';, p.getFullName( ));


}


}
