유닛테스트에 어떤 Scheduler를 사용해야하나요? MainScheduler , IoScheduler 관계없이 Schedulers.trampoline()를 사용합니다. class FetchLockScreenUnitUseCaseTest { lateinit var fetchLockScreenUnitUseCase: FetchLockScreenUnitUseCase private val scheduler = Schedulers.trampoline() @MockK(relaxUnitFun = true) lateinit var unitRepository: UnitRepository @Before fun setUp() { MockKAnnotations.init(this) fetchLockScreenUnitUseCase..

원인 로컬 유닛 테스트는 안드로이드 구성요소를 사용할 수 없습니다. 안드로이드 구성 요소인 android util Log를 찾을 수 없어 에러가 발생합니다. 해결 방법 Unit Test에 사용할 Mock Log 클래스를 생성합니다. /src/test/java/android/util 하위 경로에 아래 소스코드를 추가합니다. package android.util; public class Log { public static int d(String tag, String msg) { System.out.println("DEBUG: " + tag + ": " + msg); return 0; } public static int i(String tag, String msg) { System.out.println("IN..
