Usage

From source file:com.flicklib.service.cache.HttpEHCacheTest.java

@Test
public void testHttpCache() throws IOException {
    String testValue = UUID.randomUUID().toString();
    SourceLoader mockResolver = Mockito.mock(SourceLoader.class);
    Mockito.when(mockResolver.loadSource("test", true)).thenReturn(new Source("test", testValue, "test"));

    SourceLoader cache = new HttpEHCache(mockResolver);
    {/*from   w ww .ja  v a  2s .  c o  m*/
        Source source = cache.loadSource("test");
        assertEquals(testValue, source.getContent());
    }
    {
        Source source = cache.loadSource("test");
        assertEquals(testValue, source.getContent());
    }
    // second call should not hit the resolver so we should have only one #get call
    Mockito.verify(mockResolver).loadSource("test", true);
