Auto-Restart for Spring Boot Tests - spring-boot

Question

I am currently writing unit and integration tests for a Spring Boot application. I'm using Spring Tool Suites 4 for development.
When I run the application using Spring Tool Suites, the auto-restart works fine when I modify and save a file. I'm trying to find a similar way to run my tests.
I currently run the tests using a separate Windows CMD terminal using Maven:
mvn test
This runs one time and terminates. Is there anyway to have the tests run every time a test file is saved?
Edit: Here's an example of a test I am running that uses JUnit and Spring to run the tests. This is taken straight from the Spring.io website https://spring.io/guides/gs/testing-web/
import static org.assertj.core.api.Assertions.assertThat;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
#SpringBootTest
public class ControllerTest {
#Autowired
private Controller controller;
#Test
public void contexLoads() throws Exception {
assertThat(controller).isNotNull();
}
}

I found this Maven plugin https://github.com/fizzed/maven-plugins#watcher-fizzed-watcher-maven-plugin that will watch files and let you run specific Maven goals on file changes.
I added the plugin to my POM and changed the goal to "test".
<build>
<plugins>
<plugin>
<groupId>com.fizzed</groupId>
<artifactId>fizzed-watcher-maven-plugin</artifactId>
<version>1.0.6</version>
<configuration>
<touchFile>target/classes/watcher.txt</touchFile>
<watches>
<watch>
<directory>src/main/java</directory>
</watch>
<watch>
<directory>src/test/java</directory>
</watch>
</watches>
<goals>
<goal>test</goal>
</goals>
</configuration>
</plugin>
<plugins>
<build>
I opened a terminal within Spring Tool Suites (ctrl + alt + t) and docked it next to my console and ran the following:
mvn fizzed-watcher:run
So far this seems to be working exactly like I want.
