The import org.springframework.test.context.junit4.SpringJUnit4ClassRunner cannot be resolved

I'm a newbie at Spring and this is also my very first question on StackOverflow so I'm going to try to make this as understandable as possible.

I'm trying to make a web service client using Spring and Maven on this tutorial: and I get this error: The import org.springframework.test.context.junit4 cannot be resolved

Here is my code:

package demo;

import hello.WsClientApplication;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.SpringApplicationConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; //this won't import


@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = WsClientApplication.class)
public class WsClientApplicationTests {

    @Test
    public void contextLoads() {
    }

}

Here is my pom.xml in case you need it.

I have tried some other solutions in StackOverflow but I can't get it to work.

Thanks.

You need to add a dependency on spring-boot-starter-test:

<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-test</artifactId>
  <scope>test</scope>
</dependency>
