Hi, Something weird is happening, is the test is executed like this:

TestApplication {
    environment {
        config = ApplicationConfig("application.conf")
    }
}

Modules defined in application.conf load fine, but when I try to override any parameter of the configuration using:

TestApplication {
    environment {
        config = ApplicationConfig("application.conf").mergeWith(
            MapApplicationConfig(
                "database.host" to "whatever",
            )
        )
    }
}

Then the modules are loaded two times. Version 3.0.0-beta-1

I cannot reproduce your problem with the following code:

@Test
fun test() = testApplication {
    environment {
        config = ApplicationConfig("application.conf").mergeWith(
            MapApplicationConfig(
                "database.host" to "whatever",
            )
        )
    }

    client.get("/")
}

application.conf:

ktor {
    deployment {
        port = 9090
    }

    application {
        modules = [ EngineMainKt.main ]
    }
}

database {
    host = localhost
}

EngineMain.kt:

fun Application.main() {
    println(environment.config.property("database.host").getString())
}

I’ll prepare a report to reproduce it

The problem is different than what I thought, I can explain using this example:

object Ktor3App {
    suspend fun beforeSpec() {
        httpClient.get("/")
    }

    fun afterSpec() {}

    fun beforeTest() {}

    fun afterTest() {}

    val inMemorySpanExporter: InMemorySpanExporter
    val app: TestApplication
    val httpClient: HttpClient

    init {
        inMemorySpanExporter = InMemorySpanExporter.create()
        app = TestApplication {
            environment {
                config = ApplicationConfig("src/test/resources/application-test.conf")
            }
        }
        httpClient = app.createClient { }
    }
}

Now I know that the testApplication server will start when the first request is made, but I need to start the server after that happens so my solution is doing a get request after the tests run.

If I replace this request in beforeSpec() with app.start() it will load the modules there and then it will load then on the first client http request.

Is this correct? I think it should check if the app is running, server started and modules loaded to not load them again on the first request but no strong opinion, hopefully there is a cleaner way to do it.

If you manually create and start a TestApplication then you don't need to use the testApplication function.

I’m not using the function, just using TestApplication
