TestNG - Run your first test using ant

Let us write our First Test in TestNG and run as an ant task

Create Directory Tree Structure  as follows

testng(Base Directory)
    |
    +-------+-------------------------+---------------+------------+
    |          |                          |                 |           |

     OurFirstTestNGTest.java            OurFirstTestNGTest.class

Where as

OurFirstTestNGTest.java contains
=============================

package com.qa;

import org.testng.annotations.*;

import org.testng.*;

public class OurFirstTestNGTest {

    int testInt;

    @BeforeMethod

    public void setUp() {

        testInt = 0;

    }

    @Test

    public void addTest() {

        testInt++;

        Assert.assertEquals(testInt,1);

        System.out.println("Addition Test");

    }

    @Test

    public void subtractTest() {

        testInt--;

        Assert.assertEquals(testInt,-1);

        System.out.println("Subtract Test");

    }

}

=============================

build.xml contains
=============================

<project default="test">

 <path id="cp">

   <pathelement location="lib/testng-6.3.1.jar"/>

   <pathelement location="build"/>

 </path>

 <taskdef name="testng" classpathref="cp"

          classname="org.testng.TestNGAntTask" />

 <target name="test">

   <testng classpathref="cp">

     <classfileset dir="build" includes="**/*.class"/>

   </testng>

 </target>

</project>

=============================


Now to Compile a java class, use
#javac -classpath .:../lib/testng-6.3.1.jar -d ../build com/qa/OurFirstTestNGTest.java

To run using ant
#ant test
