Hi, I'm trying to use externalServices mocking with the 2.0.1 ktor version, but it doesn't kick in:

externalServices {
        hosts("<https://api.sendinblue.com>") {
            install(ContentNegotiation) {
                json()
            }
            routing {
                post("v3/smtp/email") {
                    call.response.status(HttpStatusCode.OK)
                }
            }
        }
    }

and then I call the API:

val response = <http://httpClient.post|httpClient.post>("<https://api.sendinblue.com/v3/smtp/email>") {
            accept(ContentType.Application.Json)
            contentType(ContentType.Application.Json)
            header("api-key", apiKey)

But this mocking doesn't kick-in, rather the real thing.

The following test passes:

@Test
fun test() = testApplication {
    externalServices {
        hosts("<https://api.sendinblue.com>") {
            install(ContentNegotiation) {
                json()
            }
            routing {
                post("v3/smtp/email") {
                    call.response.status(HttpStatusCode.OK)
                }
            }
        }
    }

    val response = <http://client.post|client.post>("<https://api.sendinblue.com/v3/smtp/email>") {
        header("api-key", "123")
    }

    assertEquals(HttpStatusCode.OK, response.status)
}

Could you please share a complete test to reproduce your problem?

What is the prerequisite for this magic to work? Do my tests need to use the same HTTP client as my production code or?

[dodalovic]

I'm calling the setup at the beginning of my @Test methods

Untitled.kt

Inside the testApplication you have the client property that you can use for testing. Also, you can create a new client with createClient method. My test passes with your setup method too.
