Quality Assurance

1. Testing Strategy

   @Test
   fun `event filtering returns correct results`() {
       runTest {
           // Given
           val repository = FakeEventRepository()
           val useCase = GetFilteredEventsUseCase(repository)
           
           // When
           val results = useCase.execute(FilterCriteria())
           
           // Then
           assertThat(results).isNotEmpty()
       }
