    inconsistent and awkward to explore.

 *  **OkHttpClient now implements the new `Call.Factory` interface.** This
    interface will make your code easier to test. When you test code that makes
    HTTP requests, you can use this interface to replace the real `OkHttpClient`
    with your own mocks or fakes.

    The interface will also let you use OkHttp's API with another HTTP client's

 * the updated response if it has changed, or a short 'not modified' response if the client's copy
 * is still valid. Such responses increment both the network count and hit count.
 *
 * The best way to improve the cache hit rate is by configuring the web server to return cacheable
 * responses. Although this client honors all [HTTP/1.1 (RFC 7234)][rfc_7234] cache headers, it
 * doesn't cache partial responses.

        final Trans2GetDfsReferralResponse resp = new Trans2GetDfsReferralResponse();
        ipc.send(new Trans2GetDfsReferral(path), resp);

        if (resp.numReferrals == 0) {
            return null;
        }
        if (rn == 0 || resp.numReferrals < rn) {
            rn = resp.numReferrals;
        }

        DfsReferral dr = new DfsReferral();

By considering these concepts, you will be able to **evaluate and design** the best way to deploy **your own APIs**.

In the next chapters, I'll give you more **concrete recipes** to deploy FastAPI applications.

### 7.1 Unit Tests

    ChannelManager manager = new ChannelManager(context, session);
    
    // Add test channels
    ChannelInfo channel1 = createTestChannel("channel1", 1000);  // 1Gbps
    ChannelInfo channel2 = createTestChannel("channel2", 10000); // 10Gbps
