KURL url(ParsedURLString, "http://127.0.0.1:8000/foo");
ImageResource* imageResource = ImageResource::create(ResourceRequest(url));
// Adds a ResourceClient but not ImageResourceObserver.
Persistent<MockResourceClient> client1 =
new MockResourceClient(imageResource);
receiveResponse(imageResource, url, "image/jpeg", jpegImage());
EXPECT_FALSE(imageResource->errorOccurred());
ASSERT_TRUE(imageResource->hasImage());
EXPECT_FALSE(imageResource->getImage()->isNull());
EXPECT_EQ(1, imageResource->getImage()->width());
EXPECT_EQ(1, imageResource->getImage()->height());
EXPECT_TRUE(client1->notifyFinishedCalled());
client1->removeAsClient();

imageResource->prune();
