We will have an example to demonstrate how to run JUnit using ANT. Follow the steps given below.
Step 1: Download Apache Ant
Download Apache Ant based on the operating system you are working on.
OS Archive Name
Windows apache-ant-1.8.4-bin.zip
Linux apache-ant-1.8.4-bin.tar.gz
Mac apache-ant-1.8.4-bin.tar.gz
Step 2: Set Ant Environment
Set the ANT_HOME environment variable to point to the base directory location, where the ANT libraries are stored on your machine. Let us assume the Ant libraries are stored in the folder apache-ant-1.8.4.
Sr.No. OS & Description
1 Windows
Set the environment variable ANT_HOME to C:\Program Files\Apache Software Foundation\apache-ant-1.8.4
2 Linux
export ANT_HOME = /usr/local/apache-ant-1.8.4
3 Mac
export ANT_HOME = /Library/apache-ant-1.8.4
Append Ant compiler location to the System Path as follows −
OS Output
Windows Append the string %ANT_HOME\bin at the end of the system variable, Path.
Linux export PATH = $PATH:$ANT_HOME/bin/
Mac not required
Step 3: Download JUnit Archive
Download a JUnit Archive that suits your operating system.
OS Archive Name
Windows junit4.10.jar
Linux junit4.10.jar
Mac junit4.10.jar
Step 4: Create Project Structure
- Create a folder TestJunitWithAnt in C:\>JUNIT_WORKSPACE.
- Create a folder src in C:\>JUNIT_WORKSPACE>TestJunitWithAnt.
- Create a folder test in C:\>JUNIT_WORKSPACE>TestJunitWithAnt.
- Create a folder lib in C:\>JUNIT_WORKSPACE>TestJunitWithAnt.
- Create MessageUtil class in C:\>JUNIT_WORKSPACE>TestJunitWithAnt> srcfolder.
* This class prints the given message on console.
*/
public class MessageUtil {
private String message;
//Constructor
//@param message to be printed
public MessageUtil(String message){
this.message = message;
}
// prints the message
public String printMessage(){
System.out.println(message);
return message;
}
// add "Hi!" to the message
public String salutationMessage(){
message = "Hi!" + message;
System.out.println(message);
return message;
}
}
Create TestMessageUtil class in the folder C:\>JUNIT_WORKSPACE>TestJunitWithAnt>src.
import org.junit.Ignore;
import static org.junit.Assert.assertEquals;
public class TestMessageUtil {
String message = "Robert";
MessageUtil messageUtil = new MessageUtil(message);
@Test
public void testPrintMessage() {
System.out.println("Inside testPrintMessage()");
assertEquals(message,messageUtil.printMessage());
}
@Test
public void testSalutationMessage() {
System.out.println("Inside testSalutationMessage()");
message = "Hi!" + "Robert";
assertEquals(message,messageUtil.salutationMessage());
}
}
Copy junit-4.10.jar onto the folder C:\>JUNIT_WORKSPACE>TestJunitWithAnt>lib.
Create ANT Build.xml
We'll be using <junit> task in Ant to execute our JUnit test cases.
<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 = "lib/junit-4.10.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 = "TestMessageUtil" />
</junit>
</target>
</project>
Run the following Ant command.
C:\JUNIT_WORKSPACE\TestJunitWithAnt>ant
Verify the output.
