Kotlin multiplatform test error ("Error_0: Fail to fetch")
I have a kotlin-multiplatform project that has a kotlinJS client and a JVM backend. I'm creating some integration tests that are supposed to test the API calls from the client. The function is a suspend function with an HttpClient call with a POST method. I'm using kotlinx-coroutines-test, the test looks like this:
@OptIn(ExperimentalCoroutinesApi::class)
@Test
fun testGetSingleResult() = runTest {
val result = getSingleResult(TESTED_ID)
assertThat(result.ID).isEqualTo(TESTED_ID)
}

It...
