Greetings. We are trying to write some tests for ktor with embeddedServer using mockk library. And we are facing some problems with mocking objects. What is the best way to test ktor application? Assuming we need to mock some stuff that goes to third-party services? Any tough samples? Thanks.

You can use https://ktor.io/docs/testing.html to generate a temporary server that fakes HTTP actions, and a Client instance that calls it

[CLOVIS]

If you want to fake a third-party service, you can just declare it as a route in that fake service, and the client will call it

We need to mock the exact object inside our app.

We already use testApplication with createClient DSLs.

testApplication {

    //mock top level getStuff() func
    mockkStatic("my.package.name.ClassKt")
    every { getStuff() } returns listOf(Stuff(), Stuff())

    // mock class
    val repository = mockk<MyRepository>()
    val target = MyService(repository)
    every { repository.save(any()) } just Runs

}
