Teste do CursoRepository findByNome com banco MySql

Meu código de teste

package br.com.alura.forum.repository;

import org.junit.Assert;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.orm.jpa.DataJpaTest;
import org.springframework.test.context.junit4.SpringRunner;

import br.com.alura.forum.modelo.Curso;

@RunWith(SpringRunner.class)
@DataJpaTest() 
public class CursoRepositoryTest {

    @Autowired
    private CursoRepository cursoRepository;

    @Test
    public void buscaCursoPeloNome() {
        String nomeCurso = "HTML 5";
        Curso curso = cursoRepository.findByNome(nomeCurso);

        Assert.assertNotNull(curso);
        Assert.assertEquals(nomeCurso, curso.getNome());

    }

}

Minha pilha de exception

java.lang.IllegalStateException: Failed to load ApplicationContext
    at org.springframework.test.context.cache.DefaultCacheAwareContextLoaderDelegate.loadContext(DefaultCacheAwareContextLoaderDelegate.java:132)


Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaConfiguration'

Caused by: java.lang.IllegalStateException: Failed to replace DataSource with an embedded database for tests. If you want an embedded database please put a supported one on the classpath or tune the replace attribute of @AutoConfigureTestDatabase.    

Será que o erro é por conta de eu estar usando o MySql
