5.0.2 is out with a bunch of fixes https://kotest.io/docs/changelog.html

[thanksforallthefish]

I just merged a dependency update to 5.0.1 5 minutes ago 😞

[sam]

ha sorry

[sam]

Now you get to make another commit!

[Big Chungus]

Are the new MPP engine setup docs available already?

[sam]

No need to do that still, help is always welcomed.

[sam]

Example project here: https://github.com/kotest/kotest-examples-multiplatform

[Big Chungus]

I would if I wouldn't need the docs myself to understand the changes :D

[sam]

hah

[sam]

definitely by the end of the weekend, I have time on sunday if not before

[Big Chungus]

Can you make a release-like announcement on #kotest once they're out so I could stop bugging you with the same questions?

[sam]

yep

[Big Chungus]

Much appreciated!

[sam]

reminders set

[Peter]

still having my testcontainers startup issue with 5.0.2 😢

[sam]

yeah I'm publishing 1.1.0 which will work with 5.0.2

[sam]

1.1.0 is out if you want to try it

[Peter]

ok cool 👀

[Peter]

still the same problem unfortunately 😞

[sam]

can you recap your issue

[Peter]

yep, working on a minimal case, brb

[Peter]

class UserSpec: WordSpec() {
    private val network = Network.newNetwork()

    private val postgresContainer = PostgreSQLContainer(DockerImageName.parse("postgres:13"))
        .withDatabaseName(config.databaseConfig.databaseName)
        .withUsername(config.databaseConfig.username)
        .withPassword(config.databaseConfig.password.value)
        .withExposedPorts(5432)
        .withNetwork(network)

    init {
        listener(postgresContainer.perSpec())

        "Users Route" should {
            "" {
                
            }

        }
    }

    override fun beforeSpec(spec: Spec) {
        println(" ${postgresContainer.firstMappedPort}")
    }
}

[Peter]

the postgresContainer.firstMappedPort fails with

[Peter]

Caused by: java.lang.IllegalStateException: Mapped port can only be obtained after the container is started
      at org.testcontainers.shaded.com.google.common.base.Preconditions.checkState(Preconditions.java:174)
      at org.testcontainers.containers.ContainerState.getMappedPort(ContainerState.java:142)
      at java.base/java.util.Optional.map(Optional.java:265)

[sam]

the perSpec listener is probably firing after your before spec

[Peter]

100% worked in 4.6.3, 100% failure in 5.x

[sam]

the order is not guaranteed and probably changed between releases

[Peter]

😢

[sam]

we can fix that by moving to a test case extension

[Peter]

i use the beforeSpec to setup the connection pool & do flyway etc

[sam]

Yeah that's fine, you just need the container to be guaranteed to fire first, I'll fix it, might take 30 mins

[Peter]

thank you!

[sam]

If you use the new jdbc container stuff, then you should be good

class UserSpec: WordSpec() {
    private val network = Network.newNetwork()

    private val postgresContainer = PostgreSQLContainer(DockerImageName.parse("postgres:13"))
        .withDatabaseName(config.databaseConfig.databaseName)
        .withUsername(config.databaseConfig.username)
        .withPassword(config.databaseConfig.password.value)
        .withExposedPorts(5432)
        .withNetwork(network)

    val ds = install(JdbcTestContainerExtension(postgresContainer)) {
       maximumPoolSize = 8
       minimumIdle = 4
    }

    init {

        "Users Route" should {
            "" {
                
            }

        }
    }

    override fun beforeSpec(spec: Spec) {
        println(" ${postgresContainer.firstMappedPort}")
    }
}
