### Kotlin
```kotlin
val response = MockResponse.Builder()
  .addHeader("Content-Type", "application/json; charset=utf-8")
  .addHeader("Cache-Control", "no-cache")
  .body("{}")
  .build()
```

MockResponse can be used to simulate a slow network. This is useful for
testing timeouts and interactive testing.

### Java
```java
MockResponse response = new MockResponse.Builder()

    client = client.newBuilder().proxySelector(proxySelector).build()

    val request = Request(server1.url("/"))

    server1.enqueue(MockResponse(200))
    server2.enqueue(MockResponse(200))
    server2.enqueue(MockResponse(200))

    println("\n\nRequest to ${server1.socketAddress}")
    executeSynchronously(request)
      .assertSuccessful()
      .assertCode(200)
