Spring JPA with PostgreSQL

This is all you need to set up PostgreSQL container inside Spring Boot Test with JUnit 5.

Test code

@SpringBootTest
@Testcontainers
internal class CatControllerTest {
    companion object {
    	@Container
    	@JvmStatic
    	val postgreSQLContainer = PostgreSQLContainer()
    
    	@DynamicPropertySource
    	@JvmStatic
    	fun postgreProperties(registry: DynamicPropertyRegistry) {
    		registry.add("spring.datasource.url", postgreSQLContainer::getJdbcUrl)
    		registry.add("spring.datasource.username", postgreSQLContainer::getUsername)
    		registry.add("spring.datasource.password", postgreSQLContainer::getPassword)
    	}
    }
}
