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.Test;
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.
<project name = "JunitTest" default = "test" basedir = ".">
<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.
