Examples of BlockheadClient

org.eclipse.jetty.websocket.common.test.BlockheadClient
A simple websocket client for performing unit tests with.
This client will use {@link HttpURLConnection} and {@link HttpsURLConnection} with standard blocking calls to perform websocket requests.
This client is NOT intended to be performant or follow the websocket spec religiously. In fact, being able to deviate from the websocket spec at will is desired for this client to operate properly for the unit testing within this module.
The BlockheadClient should never validate frames or bytes being sent for validity, against any sort of spec, or even sanity. It should, however be honest with regards to basic IO behavior, a write should work as expected, a read should work as expected, but what byte it sends or reads is not within its scope.
