[Brent Beardsley]

Is there a way to use OkHttp ktor client in a testApplication block? We're seeing channel closed issues with the default client and was trying to work around it.

No, there is no way. Could you please describe your problem with testApplication in more detail?

[Brent Beardsley]

These are integration tests where we're hitting an actual test server. We don't see any errors on the server but on the client (doing a get) are seeing:

The underlying implementation of testApplication doesn’t do network requests. Could you please describe how do you use the testApplication if you use it at all?
