Sample code as below :
`@RunWith(PowerMockRunner::class)
@PrepareForTest(VideoCache::class, SimpleCache::class)
class VideoCacheTest {
private lateinit var simpleCache: SimpleCache
private val videoCache = PowerMockito.mockStatic(VideoCache::class.java)
private val context = PowerMockito.mock(Context::class.java)

@Before
fun setup(){
    simpleCache = VideoCache.getInstance(context)
    //PowerMockito.`when`(VideoCache.getInstance(context)).thenReturn(simpleCache)
}

@Test
fun testGetInstanceVideoCache() {
    assertEquals("",simpleCache, VideoCache.getInstance(context))
}

}`

`object VideoCache {
private var downloadCache: SimpleCache? = null
private var downloadContentDirectory:File? = null
private var databaseProvider:StandaloneDatabaseProvider? = null
private const val dirName: String = "Sample"

@Synchronized
fun getInstance(context : Context): SimpleCache {
    if (downloadCache == null) {
        downloadContentDirectory = File(context.cacheDir, dirName)
        databaseProvider = StandaloneDatabaseProvider(context)
        downloadCache = SimpleCache(downloadContentDirectory!!, NoOpCacheEvictor(), databaseProvider!!)
    }
    return downloadCache as SimpleCache
}

fun clearCache() {
    if(downloadContentDirectory != null && databaseProvider != null) {
        try {
            downloadCache?.release()
            SimpleCache.delete(downloadContentDirectory!!, databaseProvider!!)
            downloadContentDirectory = null
            databaseProvider = null
            downloadCache = null
        }catch (e:Exception){

        }
    }
}
