In the following block of testing code:

@Test
    fun testFetchReport() = testApplication {
        setup()

        println("After setup")
    }

The line “After setup” is printed is executed before setup(). What would possibly cause this? Here’s what’s in setup():

fun ApplicationTestBuilder.setup() {
    application {
        configureApplication()
        configureTestDatabase()
    }
    client.config {
        install(io.ktor.client.plugins.resources.Resources)
    }
}

Configure test database consists of Exposed configuration and connection. Configure application is for other modules.
Edit: Seems like this is caused by Exposed implicitly initializing in different thread

Can you share simplified definitions of the configureTestDatabase and configureApplication methods to reproduce the problem?

I found the problem. What’s relevant is that inside configureTestDatabase , which is inside the application block, I call Exposed’s Database.connect() . By moving it outside of the application block, the code runs sequentially.
