You can change the log level at any time by calling `setLevel()`.

To log to a custom location, pass a `Logger` instance to the constructor.
```java
HttpLoggingInterceptor logging = new HttpLoggingInterceptor(new Logger() {
  @Override public void log(String message) {
    Timber.tag("OkHttp").d(message);
  }
});
```

Alternately you may add the [MockWebServer] as a constructor parameter:

```
class MyTest {
  private final MockWebServer server;

  MyTest(MockWebServer server) {
    this.server = server;
  }

  @Test
  void test() {
    ...
  }
}
```

Constructor injection is particularly concise in Kotlin:

```
class MyTest(

/**
 * Platform using OpenJSSE (https://github.com/openjsse/openjsse) if installed as the first
 * Security Provider.
 *
 * Requires org.openjsse:openjsse >= 1.1.0 on the classpath.
 */
class OpenJSSEPlatform private constructor() : Platform() {
  private val provider: Provider = org.openjsse.net.ssl.OpenJSSE()

  // Selects TLSv1.3 so we are specific about our intended version ranges (not just 1.3)

 * The format of the logs created by this class should not be considered stable and may change
 * slightly between releases. If you need a stable logging format, use your own event listener.
