 ##### Tuning
 
 * Tests can communicate with server via real HTTP client or invoke `net/http` or [`fasthttp`](https://github.com/valyala/fasthttp/) handler directly.
-* Custom HTTP client, logger, printer, and failure reporter may be provided by user.
+* Custom HTTP client and WebSocket dialer may be provided by user.
 * Custom HTTP request factory may be provided, e.g. from the Google App Engine testing.
+* Custom handlers may be provided for printing requests and responses, logging, formatting and reporting failures.
