I'm using ktor cli. Is there a way to create a fake of HttpResponse? I would like to use it to test a function that receives an HttpResponse and returns a Result. I know that I could use MockEngine to create a HttpResponse but it feels too much. I'm assuming that HttpResponse is something similar as Response in Retrofit. And there I could use Response.error() or Response.success() to create fakes.

Unfortunately, there is no easy way to do it. Here you can find a way of doing it.

😢 yes I found that but I don't want to use mockk or mockito... I tried to create a fake myself but it's not possible to create a fake of HttpClientCall because its constructor is internal.

I had a problem where one of the possible solutions was that HttpClientCall was not internal, @Aleksei Tirman [JB] is it possible to change it to public?

Could you log an issue? It's possible to fix before 2.0.0

_< I make it work with mockk but now my first test needs 2 seconds to finish. I'll open an issue to find a better way,

internal inline fun <reified T : Any> fakeHttpResponse(
    status: HttpStatusCode,
    value: T,
): HttpResponse {
    return mockk {
        every { [e-mail] } returns status
        coEvery { receive<T>() } returns value
    }
}

Can you share the issue here @Brais Gabin ?

[Brais Gabin]

I'll

Please add the possibility to change the visibility to HttpClientCall too

[Brais Gabin]

Yes, I'll add a link to this converation too

[Javier]

Thanks

Additionally, there are internal functions to create those objects too, so maybe the constructor can still be private/internal but those functions should be public instead

your welcome!
