How to implement JUnit test case with Ant script ?

Before creating any test case you will need Java compiler, Ant and JUnit.

You will also need junit.jar in your Ant's library folder.

Example

<property name="testdir" location="test" />

<property name="srcdir" location="src" />

<property name="full-compile" value="true" />

<path id="classpath.base" />

<path id="classpath.test">

  <pathelement location="/apache-ant-1.7.1/lib/junit-3.8.1.jar" />

  <pathelement location="/apache-ant-1.7.1/lib/junit-3.8.jar" />

  <pathelement location="${testdir}" />

  <pathelement location="${srcdir}" />

  <path refid="classpath.base" />

</path>

<target name="clean" >

  <delete verbose="${full-compile}">

    <fileset dir="${testdir}" includes="**/*.class" />

  </delete>

</target>

<target name="compile" depends="clean">

  <javac srcdir="${srcdir}" destdir="${testdir}" verbose="${full-compile}" >

    <classpath refid="classpath.test"/>

  </javac>

</target>

<target name="test" depends="compile">

  <junit>

    <classpath refid="classpath.test" />

    <formatter type="brief" usefile="false" />

    <test name="JUnitTestExample" />

  </junit>

</target>

Create a JUnitTestExample.java file in the src directory as given below.

public class JUnitTestExample extends TestCase {

  public void testCase1() {

    assertTrue( "TestExample", true );

  }

}
