Answer 1

You can use Mocking frameworks like Mockito

In your JUnit Test you can do something like

public class YourTest {

  private ProductcacheDao productCacheDaoMock;

  @Before
  public void setup() throws Exception {

    productCacheDaoMock = Mockito.mock(ProductcacheDao.class);

  }

  @org.junit.Test
  public void test() {
      // Given
      Mockito.when(productCacheDaoMock.getProductLookUpData()).thenThrow(new RuntimeException());

      // When
      // do your stuff
      productCacheDaoMock.getProductLookUpData();

      // Then
      // ...
  }

}
