    Configure basic logging like this:

    ```java
    HttpLoggingInterceptor loggingInterceptor = new HttpLoggingInterceptor();
    loggingInterceptor.setLevel(HttpLoggingInterceptor.Level.BASIC);
    client.networkInterceptors().add(loggingInterceptor);
    ```

    **Warning:** Avoid `Level.HEADERS` and `Level.BODY` in production because

      MockResponse.Builder()
        .body("abc")
        .build(),
    )
    client =
      client.newBuilder()
