How do I use MockEngine (https://ktor.io/clients/http-client/testing.html)? I can see how I can set it up, but I have a class with a private

HttpClient

Your class has to accept an engine via it's ctor or something.

I started doing something like that, but with whole config, problem was that I must remember to make my tests have same install as my service, and

client.config { install  { ... }}

didn't seem to work. But passing the engine doesn't have that problem so it might be a good idea, giving it a try

You can pass

Apache.create {}

Nice, then I can do

engine : HttpClientEngine = Apache.create()

in ctor, and to create

MockEngine

I can do

MockEngine.create { addHandler { ... } }

and pass that in ctor. Thanks!
