Does Ktor’s

HttpClient

kick off it’s own coroutine to make requests? And do we have any control over that coroutineContext? I’m having trouble getting ktors HttpClient to behave nicely in regards to synchronization. Unless I wrap the

.get()

in

withContext(runTest.coroutineContext)

my tests do not wait for ktor request to return and the test will complete prematurely

The

HttpClient

implements

CoroutineScope

and has public

coroutineContext

property.

HttpClient().coroutineContext

Yes it has coroutine context but it can not be changed.

runTest {
            client.engine.coroutineContext = this.coroutineContext
            viewModel.getMain()
        }

Essentially without wrapping the HttpClient call in

withContext(someContext)

and setting

someContext

as TestScope.coroutineContext. The test will complete before HttpClient call returns. I’m having trouble acheiving synchronous mechanism without wrapping in

withContext

Could you please share the definition of the

runTest

function? In what environment the

runTest

is executed?

@Ky If you use MockEngine, you could inject your test dispatcher.

val engine = MockEngine.config {
    dispatcher = StandardTestDispatcher(testScheduler)

    addHandler {
        respondOk(resp)
    }
}

val http = HttpClient(engine)
// inject the http client into your code
