我有多个测试类运行相同的 docker-compose 和testcontainer。

initializationError尽管每个测试在单独执行时都通过了，但该套件失败了。

这是第二次测试期间发生的堆栈跟踪的相关部分。 ./gradlew e2e:test -i

在我看来，第二个测试并没有等待第一个关闭以前的容器。

这里是所有测试继承的基类。它负责启动容器。

open class BaseE2eTest {

    ...

    companion object {
        const val A = "containera_1"
        const val B = "containerb_1"
        const val C = "containerc_1"

        val dockerCompose: KDockerComposeContainer by lazy {
            defineDockerCompose()
                .withLocalCompose(true)
                .withExposedService(A, 8080, Wait.forListeningPort())
                .withExposedService(B, 8081)
                .withExposedService(C, 5672, Wait.forListeningPort())
        }

        class KDockerComposeContainer(file: File) : DockerComposeContainer<KDockerComposeContainer>(file)

        private fun defineDockerCompose() = KDockerComposeContainer(File("../docker-compose.yml"))

        @BeforeAll
        @JvmStatic
        internal fun beforeAll() {
            dockerCompose.start()
        }

        @AfterAll
        @JvmStatic
        internal fun afterAll() {
            dockerCompose.stop()
        }
    }
}

docker-compose version 1.27.4, build 40524192
testcontainer 1.15.2
testcontainers:junit-jupiter:1.15.2

看完这个演讲后，我意识到我使用 Junit5 的 testcontainers 实例化方法是错误的。

这是工作代码：

@TestInstance(TestInstance.Lifecycle.PER_CLASS)
open class BaseE2eTest {

    ...

    val A = "containera_1"
    val B = "containerb_1"
    val C = "containerc_1"

    val dockerCompose: KDockerComposeContainer by lazy {
        defineDockerCompose()
            .withLocalCompose(true)
            .withExposedService(A, 8080, Wait.forListeningPort())
            .withExposedService(B, 8081)
            .withExposedService(C, 5672, Wait.forListeningPort())
    }

    class KDockerComposeContainer(file: File) : DockerComposeContainer<KDockerComposeContainer>(file)

    private fun defineDockerCompose() = KDockerComposeContainer(File("../docker-compose.yml"))

    @BeforeAll
    fun beforeAll() {
        dockerCompose.start()
    }

    @AfterAll
    fun afterAll() {
        dockerCompose.stop()
    }
}

现在测试套件通过了。
