After updating to Compose 1.2 we have a ton of flaky UI tests (end-to-end tests). •

Test instrumentation process crashed.

app simply stops responding to some focus event and then instrumentation timeouts after 5 seconds, what's more, the interaction is on non-compose view at this particular time. •

java.lang.IllegalStateException: No compose hierarchies found in the app. Possible reasons include ...

suddenly this started happening, but not always - probably tests access activity too early, seems like idling resource issue, but this was not happening at all before update • Compose recomposing forever - timeouting because not able to reach an idle state - this was only issue I was able to fix - we were missing

remember

, but actually without UI test no repeated recomposition was happening there Do you any similar experience, tips where to look for issues/errors/fixes?

Is there any way to get a timestamp (like System.currentTimeMillis()) in a multiplatform project without using expect/actual?

How to mock a method with context receiver? Here's my setup:

interface AProvider {
    context(ContextProvider)
    fun getA(a: String) = a
}

class ContextProvider

inline fun <reified T : Any> mockkWithContext(noinline block: context(ContextProvider) T.() -> Unit) =
    withContext { mockk<T> { block(this@withContext, this@mockk) } }

fun <T> withContext(block: ContextProvider.() -> T) = ContextProvider().block()

class ContextReceiversTest {
    @Test
    fun `a test`() {
        val aProviderMock: AProvider = mockkWithContext {
            every { getA(any()) } answers { firstArg() }
        }
        println(withContext { aProviderMock.getA("a") })
    }
}

As you can see the getA method has

ContextProvider

as a receiver. In order to mock it in the test I have to wrap standard

mockk

in

withContext

which provides the required receiver for

getA

. If I run the test, though, it fails on

io.mockk.MockKException: no answer found for: AProvider(#1).getA(com.example.playground.ContextProvider@38b5f25, a)

Apparently mockk expects the receiver as the first argument but obviously I cannot write

every { getA(any(), any()) }

. So my question is how can I mock the method in my case?

I am usinge the

Intent.ACTION_OPEN_DOCUMENT_TREE

to let the user choose a directory and get access to this directory. It works but unfortunately the access is only temporary when the user closes the app and opens the app again i need to open the directory picker again. Especially for development this is very unpleasent. Of course i could ask the user for MANAGE_EXTERNAL_STORAGE permission but Google do not want this anymore for normal apps. My app is just a video player. But i need access to the directory to load subtitle files.

I’m trying to set up Flyway to work with H2 in a spring boot 3 r2dbc app (Flyway is working when I connect to mysql instead). In application.yml I have:

spring:
  r2dbc:
    url: r2dbc:h2:mem:///~/db/
    name: testdb
    username: sa
    password:
  flyway:
    url: jdbc:h2:mem:///~/db/testdb
    user: ${spring.r2dbc.username}
    password: ${spring.r2dbc.password}
    baseline-on-migrate: true

Then I have in `V1_1__create_users_and_posts_tables.sql`:

CREATE TABLE IF NOT EXISTS users
(
     id bigint NOT NULL AUTO_INCREMENT,
     username varchar(255) NOT NULL DEFAULT '',
     email varchar(255) NOT NULL DEFAULT '',
     phoneNumber varchar(255) NOT NULL DEFAULT '',
     PRIMARY KEY (id)
);

CREATE TABLE IF NOT EXISTS posts
(
     id bigint NOT NULL AUTO_INCREMENT,
     userId bigint NOT NULL,
     title varchar(255) NOT NULL DEFAULT '',
     description varchar(255) NOT NULL DEFAULT '',
     PRIMARY KEY (id)
);

It works but it creates a PUBLIC schema:

Database: jdbc:h2:mem:///~/db/testdb (H2 2.2)
Flyway upgrade recommended: H2 2.2.224 is newer than this version of Flyway and support has not been tested. The latest supported version of H2 is 2.2.220.
Schema history table "PUBLIC"."flyway_schema_history" does not exist yet
Successfully validated 2 migrations (execution time 00:00.009s)
Creating Schema History table "PUBLIC"."flyway_schema_history" ...
Current version of schema "PUBLIC": << Empty Schema >>
Migrating schema "PUBLIC" to version "1.1 - create users and posts tables"
Migrating schema "PUBLIC" to version "2.1 - create images table"
Successfully applied 2 migrations to schema "PUBLIC", now at version v2.1 (execution time 00:00.003s)

But when I call one of my api endpoints, I see this error:

Caused by: io.r2dbc.spi.R2dbcBadGrammarException: Table "USERS" not found (this database is empty);

I tried changing the testdb name for PUBLIC in my application file and creating the tables under the PUBLIC schema but I still get the same error. Any ideas anyone ? (The repo is here: https://github.com/danygiguere/spring-boot-3-reactive-with-kotlin-coroutines)

Hello! I am using Compose edge to edge (on fullscreen). How to properly apply WindowInsets.systemBars to material2 TopAppBar ? I will describe some solutions inside a thread 🧵 Maybe someone can find another solutions?

Did anyone figure out how to configure JaCoCo in a KMM project? It started with the Compose for Desktop Template (from the Wizard), but it does not seem possible to activate JaCoCo if also the "android-library" plugin is applied. So is there no way to report code coverage to sonarqube via gradle in Multiplatform projects?

I wish compose multiplatform had better back handling for iOS. Most native iOS apps use a cupertino style navigation where if the user drags the screen horizontally (enough pixels), they are taken back to the previous screen. At the moment, I don’t think that’s available on the compose navigation api.

How we can integrate FireBase sdk to Compose Desktop ?

What is the difference between an interface and a data class?
