如何用Spring data r2dbc替换测试中的@Sql？

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-r2dbc</artifactId>
</dependency>
<dependency>
    <groupId>io.r2dbc</groupId>
    <artifactId>r2dbc-postgresql</artifactId>
</dependency>

import org.springframework.data.repository.reactive.ReactiveCrudRepository;

public interface UserRepository extends ReactiveCrudRepository<User, Long> {
}

import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.data.r2dbc.DataR2dbcTest;
import reactor.test.StepVerifier;

@DataR2dbcTest
public class UserRepositoryTest {

    @Autowired
    private UserRepository userRepository;

    @Test
    public void testInsertUser() {
        User user = new User("John Doe", "john.doe@example.com");
        StepVerifier.create(userRepository.save(user))
                .expectNextCount(1)
                .verifyComplete();
    }
}
