如何在测试时使用MicronautTest和Kotlintest注入beans？在Kotlin中

// Micronaut
implementation("io.micronaut:micronaut-inject")
implementation("io.micronaut:micronaut-runtime")
implementation("io.micronaut.test:micronaut-test-junit5")

// Kotlintest
testImplementation("io.kotlintest:kotlintest-runner-junit5")

import io.kotlintest.shouldBe
import io.micronaut.context.ApplicationContext
import io.micronaut.runtime.server.EmbeddedServer
import io.micronaut.test.annotation.MicronautTest
import org.junit.jupiter.api.Test

@MicronautTest
class MyServiceTest(private val myService: MyService) {

    @Test
    fun testMyService() {
        val result = myService.doSomething()
        result shouldBe "expectedResult"
    }
}

import javax.inject.Singleton

@Singleton
class MyServiceImpl : MyService {

    private val dependency: SomeDependency

    init {
        // 初始化依赖
    }

    override fun doSomething(): String {
        // 实现业务逻辑
        return "expectedResult"
    }
}

interface MyService {
    fun doSomething(): String
}
