prevents connection reuse. Each connection pool holds its own set of
    connections alive so applications that have many pools also risk exhausting
    memory!

    The best practice in OkHttp 3 is to create a single OkHttpClient instance
    and share it throughout the application. Requests that needs a customized

  @ParameterizedTest
  @ArgumentsSource(ProtocolParamProvider::class)
  fun pingsTransmitted(
    protocol: Protocol,
    mockWebServer: MockWebServer,
  ) {
    setUp(protocol, mockWebServer)
    // Ping every 500 ms, starting at 500 ms.
    client =
      client.newBuilder()
        .pingInterval(Duration.ofMillis(500))
        .build()

    // Delay the response to give 1 ping enough time to be sent and replied to.

 * Reusing connections and threads reduces latency and saves memory. Conversely, creating a client

 * Use `new OkHttpClient()` to create a shared instance with the default settings:
