使用 r2dbc 设置集成测试

        mysql.start()
        val statements: List<String> = Arrays.asList( //
            "DROP TABLE IF EXISTS customer;",
            "CREATE TABLE customer ( id SERIAL PRIMARY KEY, firstname VARCHAR(100) NOT NULL, lastname VARCHAR(100) NOT NULL);"

    fun generatesIdOnInsert() {
        val domainMetadata = customer(1L, "John", "Smith")
        orderDomain?.save(domainMetadata) //
            ?.`as`(StepVerifier::create) //
            ?.assertNext { actual ->
                assertThat(domainMetadata.id).isNull() // immutable before save
                assertThat(actual.id).isNotNull() // after save
            }?.verifyComplete()
    }
}

我正在尝试使用 R2DBCRepositories 在 R2DBC 上运行集成测试来测试我们的一些东西。我想知道我有这个，除了没有运行任何本地数据库的事实

有没有人知道在这个测试中设置数据库的建议？

事实证明，Kotlin 不喜欢它在 Java 中的设置方式是一个问题。
