very basic… but why this test code is not compiling on the install statement?

@Test
    fun testOptimizeRouter() = testApplication {
        val client = createClient {
            install(ContentNegotiation) {
                json()
            }
        }
        // omitted
     }

because install matches the client as well as the server plugin dsl

[Luiz Aguiar]

@hfhbd not sure if I followed
this declaration is everywhere on Ktor's documentation and samples, what's is the point again that might be the problem?

[hfhbd]

install is used in the client config dsl as well as in the server config dsl. Because you use application { and inside this scope, you call client {, there is a mismatch because both have an install function.

I think the problem is simpler and you try to install server ContentNegotiation plugin into client. Please check your imports.

@Rustam Siniukov you nailed it… the import was pointing to the server plugin, additionally I had to added ktor-client-content-negotiation dependency to be able to use the client version of the plugin… a bit tricky tbh, but worked in the end.
