How to import the '#Test' method in Java - junit

Question

I am trying to use the #Test function on a small program as I am directed to using Java 8 tutorial on youtube. Find it here.
I am up to lesson 2 which starts at 21:59.
Here is the youtube link.

However, I have the following errors:
When trying to import the Test function the advice given by my Apache Netbeans IDE is ...
"package org.junit does not exist"
... the same happens for "org.Assert"
Over the "#Test" function on line 9 of my PersonTest.java file, the IDE gives the error...
"Cannot find symbol".
The same error exists over the "assertEquals" method on line 13.
Attempted Solution 1: Search dependency at Maven Repositories for org.junit.Test.
Result 1: "No matching items."
Attempted Solution 2: write the dependencies into the pom.xml file.
Result: n/a. Nothing happened.
My code on the PersonTest.java file:
package com.marcusbiel.javacourse.lesson2;
import org.junit.Test;
import org.Assert.assertEquals;
public class PersonTest {
#Test
public void shouldReturnHelloWorld() {
Person tristan = new Person();
assertEquals("Hello World",tristan.helloWorld() );
}
}
My code on the Person.java file:
package com.marcusbiel.javacourse.lesson2;
public class Person {
public String helloWorld(){
return "Hello World";
}
}
My code on the pom.xml file:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

<dependency>

<artifactId>junit</artifactId>
<version>3.8.1</version>
<scope>test</scope>
</dependency>
</dependencies>
</project>
Note: I tried to fix the problem by adding in the...
"
<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>3.8.1</version>
<scope>test</scope>
</dependency>
</dependencies>
... part. I don't think it's working. I have no feedback from the program on that note.
When I run it. I want to see a messaging saying "all tests passed". As in the video here... (I have a timestamp on this link where the outcome occurs).

Answer 1

Problem is very old JUnit version 3.8.1 (from 2007) combined with code that requires JUnit 4.
Issue can be solved by using Junit 4:
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.12</version>
<scope>test</scope>
</dependency>
Also Assert.assertEquals import is wrong. Should be:
import static org.junit.Assert.assertEquals;

Answer 2

I think that you should clean up and update your project dependencies.
Perform a mvn clean install from netbeans IDE.
This will update your project dependencies. I think this will solve the issue of unresolvable dependencies.
Here is the doc to using maven with netbeans
