Run @DataJpaTest, Spring Data Test along with Swagger Config in separate class

I am trying to run a DAO test using

@RunWith(SpringRunner.class)
@DataJpaTest

I have my Application class.

@SpringBootApplication
@EnableAspectJAutoProxy
@EnableTransactionManagement
@EnableJpaRepositories(basePackages="com.eeposit.lattice.dao")
@EnableAsync
@EnableScheduling
@ComponentScan({"com.eeposit.lattice"})
@ImportResource("classpath:config/transactional.xml")
@EnableJpaAuditing
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

    @Bean
    public Executor getAsyncExecutor() {

        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
        executor.setCorePoolSize(7);
        executor.setMaxPoolSize(42);
        executor.setQueueCapacity(11);
        executor.initialize();
        return executor;

    }
}


@Configuration
@EnableSwagger2
public class SwaggerConfig {

    @Bean
    public Docket api() {

        return new Docket(DocumentationType.SWAGGER_2)
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.eeposit.lattice.controller"))
                .paths(PathSelectors.any())
                .build()
                .apiInfo(apiInfo());

    }       

    private ApiInfo apiInfo() {

        return new ApiInfo(
                "Lattice API", 
                "Description of APIs", 
                "v1", 
                "Terms of Service", 
                new Contact("EeposIT Services", "", ""), 
                "License of API", "API license URL", Collections.emptyList());
    }

}

When I try to run the test it shows error with SpringFox Swagger bean error. By searching, I found many suggestions to separate the Swagger configuration class from application(which I already had). But didn't solve the issue.

How can this error be solved ? I am using Spring Boot 2.0.2 and Swagger 2.8.0.
