testing everything. You can even copy & paste HTTP responses from your real web
server to create representative test cases. Or test that your code survives in
awkward-to-reproduce situations like 500 errors or slow-loading responses.


### Example

Use MockWebServer the same way that you use mocking frameworks like
[Mockito](https://github.com/mockito/mockito):

1. Script the mocks.
2. Run application code.

/**
 * A connection to a remote web server capable of carrying 1 or more concurrent streams.
 *
 * Connections are shared in a connection pool. Accesses to the connection's state must be guarded
 * by holding a lock on the connection.
 */
class RealConnection(
  val taskRunner: TaskRunner,
  val connectionPool: RealConnectionPool,
  override val route: Route,
  /** The low-level TCP socket. */

## Version 4.12.0

 *  Fix: Don't hang taking headers for HTTP 103 responses.

 *  Fix: Recover gracefully when a cache entry's certificate is corrupted.

 *  Fix: Fail permanently when there's a failure loading the bundled public suffix database.
    This is the dataset that powers `HttpUrl.topPrivateDomain()`.

 *  Fix: Immediately update the connection's flow control window instead of waiting for the

    client.newCall(request).enqueue(callback)
    callback.await(request.url).assertHandshake()
  }

  @Test
  fun recoverWhenRetryOnConnectionFailureIsTrue() {
    // Set to 2 because the seeding request will count down before the retried request does.
    val requestFinished = CountDownLatch(2)
    val dispatcher: QueueDispatcher =
      object : QueueDispatcher() {

   * the String used to construct them is no longer strongly referenced outside of the CipherSuite.
   */
  @Test
  fun instancesAreInterned_survivesGarbageCollection() {
    // We're not holding onto a reference to this String instance outside of the CipherSuite...
    val cs = forJavaName("FakeCipherSuite_instancesAreInterned")
    System.gc() // Unless cs references the String instance, it may now be garbage collected.

 * In order to avoid confusion and discourage phishing attacks, [IDNA Mapping][idna] transforms
 * names to avoid confusing characters. This includes basic case folding: transforming shouting
 * `SQUARE.COM` into cool and casual `square.com`. It also handles more exotic characters. For
 * example, the Unicode trademark sign (™) could be confused for the letters "TM" in

 *  Fix: Change fast fallback to race TCP handshakes only. To avoid wasted work, OkHttp will not
    attempt multiple TLS handshakes for the same call concurrently.
 *  Fix: Don't crash loading the public suffix database in GraalVM native images. The function
    `HttpUrl.topPrivateDomain()` uses a resource file to identify private domains, but we didn't
    include this file on GraalVM.
