How to setup java junit testing frame work

Download the .jar files by visiting ThisUrl

1- Click the link for junit.jar Find the row for the latest stable release then under the downloads column click jar link. This will download a file junit-X.Y.jar

2- Repeat this again and download the latest stable release for hamcrest hamcrest-core-XX.YY.jar

Create a jUnit Home folder.

1- We need to create a folder and put the .jars you downloaded into this folder. I suggest creating a folder called java (or your project name) in your home directory by running cd && mkdir {{project_name}}

2- Run cp ~/Downloads/{junit-X.Y.jar,hamcrest-core-XX.YY.jar} ~/java/ to copy the two .jars there and make sure to replace X, Y, XX, YY accordingly

Edit and Export in .bashrc || .zshrc.

1- Edit your classpath. We now need to edit our .bash_profile file to add these files to our classpath (if you are using zsh edit your .zshrc file)

2- Paste the below in you .bash_profile || .zshrc

export JUNIT_HOME="$HOME/java"
export PATH="$PATH:$JUNIT_HOME"
export CLASSPATH="$CLASSPATH:$JUNIT_HOME/junit-X.Y.jar:$JUNIT_HOME/hamcrest-core-XX.YY.jar"

3- Save

4- Test it works. Restart your terminal. Run echo $CLASSPATH, there should be no errors that complain that files are unable to be found

5- create a file called anasTest.java with:

import junit.framework.TestCase;
public class anasTest extends TestCase {
  public void testTrue() {
    assertTrue(true);
  }
}

5- Now cd into the project directory and run javac anasTest.java

6- Run java org.junit.runner.JUnitCore anasTest If everything is ok, then you will get an output like:

JUnit version x.xx

Time: 0.006

OK (1 test)
