Why don't JUnit tests work in Ant Build System?

Question

Why don't JUnit tests work in Ant Build System?

I am new to Java, so please be careful. I am trying Ant Build System to run JUnit tests. But when I run my tests without Ant, it passes, but when I use Ant Build to run JUnit tests, the tests do not work.

Here is my Ant build.xml file:

 <property name="lib.dir" value="lib"/> <path id="classpath"> <fileset dir="${lib.dir}" includes="*.jar"/> </path> <target name="runjunit" depends="compile"> <mkdir dir="reports" /> <junit printsummary="true" showoutput="yes" haltonerror="yes" haltonfailure="yes" > <test name="com.geometry.CartesianPositionTest" /> <classpath> <path refid="classpath" /> <pathelement location="out" /> </classpath> </junit> </target> <target name="compile"> <javac srcdir="src" destdir="out" includeantruntime="false" classpath="lib/junit-4.11.jar"/> </target> <target name="package" depends="compile"> <jar destfile="geometry.jar" basedir="out" includes="**" excludes="**/*Test*" > <manifest> <attribute name="Main-Class" value="com.geometry.CartesianPosition" /> </manifest> </jar> </target>

And Ant Build stack traces:

Test file:

 package com.geometry; import org.junit.Test; import java.util.Arrays; import static org.junit.Assert.assertEquals; public class CartesianPositionTest { @Test public void testShouldReturnTheEndPointsOfLine() throws Exception { CartesianPosition position = new CartesianPosition(0, 0, 0, 0); assertEquals(Arrays.asList(0, 0, 1, 1), position.getPositions()); } @Test public void testCheckForLengthBetweenZeroAndOne() throws Exception { CartesianPosition line = new CartesianPosition(0, 0, 1, 1); assertEquals(1, line.length()); } }

And the main file:

 package com.geometry; import java.util.ArrayList; public class CartesianPosition { private int x1, y1, x2, y2; public int length; public CartesianPosition(int positionX1, int positionY1, int positionX2, int positionY2) { this.x1 = positionX1; this.y1 = positionY1; this.x2 = positionX2; this.y2 = positionY2; } public Object getPositions() { ArrayList<Integer> list = new ArrayList<Integer>(); list.add (0); list.add (0); list.add (1); list.add (1); return list; } public int length() { return 1; } }

I managed to get it to work with the assembly file below. Ant tried to run it as a junit 3 style test instead of 4. I believe this is due to a language level of 1.5. I also had to compile tests. After that, a NoClassDef error occurred for org/hamcrest/SelfDescribing . This was resolved by adding a hamcrest jar to lib.

How to fix:

Install the original version above 1.5
Compile test classes
Add hamcrest-all-1.3.jar to lib

build.xml

 <project name="CartesianPosition" basedir="."> <property name="java.sdk" value="1.6"/> <property name="lib.dir" value="lib"/> <property name="main.src" value="src"/> <property name="main.out" value="out/classes"/> <property name="test.src" value="test"/> <property name="test.out" value="out/testClasses"/> <property name="reports" value="reports"/> <property name="artifact" value="out/geometry.jar"/> <path id="mainClasspath"> <path> <fileset dir="${lib.dir}" includes="*.jar"/> </path> </path> <path id="testClasspath"> <path refid="mainClasspath"/> <pathelement location="${main.out}"/> <pathelement location="${test.out}"/> </path> <target name="clean"> <delete dir="out"/> <delete dir="${reports}"/> </target> <target name="compile"> <mkdir dir="${main.out}"/> <javac srcdir="${main.src}" destdir="${main.out}" includeantruntime="false" classpathref="mainClasspath" target="${java.sdk}" source="${java.sdk}"/> </target> <target name="testCompile" depends="compile"> <mkdir dir="${test.out}"/> <javac srcdir="${test.src}" destdir="${test.out}" includeantruntime="false" classpathref="testClasspath" target="${java.sdk}" source="${java.sdk}"/> </target> <target name="test" depends="testCompile"> <mkdir dir="${reports}"/> <junit printsummary="withOutAndErr"> <classpath refid="testClasspath"/> <formatter type="xml"/> <batchtest fork="true" todir="${reports}"> <fileset dir="${test.out}"> <include name="**/*Test.class"/> </fileset> </batchtest> </junit> </target> <target name="package" depends="compile"> <jar destfile="${artifact}" includes="${main.out}"> <manifest> <attribute name="Main-Class" value="com.geometry.CartesianPosition"/> </manifest> </jar> </target> </project>

Why don't JUnit tests work in Ant Build System?
