Kickstart jUnit 4 example

First steps in jUnit.


import org.junit.*;
import static org.junit.Assert.*;


/**

*/
public class XTest {
    @Before
    // Will be performed before each test.
    public void testSetup(){
        System.out.println("Setup for test complete.");
    }

    @After
    // Will be performed after each test.
    public void testComplete() {
        System.out.println("Test complete.");
    }

    @Test
    public void test1() {
        System.out.println("Starting test 1.");
        assertTrue( true ) ;
    }

    @Test
    public void test2(){
        System.out.println("Starting test 2.");
        assertTrue( true ) ;
    }
}



We could call it easy with maven command

mvn test

mvn test -Dsurefire.useFile=false - outputs more information about the errors.

The output of the program is:


Running XTest
Setup for test complete.
Starting test 1.
Test complete.
Setup for test complete.
Starting test 2.
Test complete.
Tests run: 2, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.062 sec

Results :

Tests run: 2, Failures: 0, Errors: 0, Skipped: 0


The maven configuration for junit is

  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <!--version>3.8.1</version-->
      <version>4.8.1</version>
      <scope>test</scope>
    </dependency>
    ...
  </dependencies>

jUnit classes are placed in [project-home]\src\test\java\[junit package]\[junit class]
