Custom servlet which enables setting component's communication id's with setId()-method

Experimental utilities (DiagnosticServlet and DiagnosticInterceptor) for tests and diagnostics.


Experimental and simple custom servlet which enables setting component's communication id's. This will help one to write scalability tests for Vaadin with e.g JMeter or Gatling.

For VAADIN 8.1 use ConnectorIdGenerator add-on instead

See the following wiki articles for more information about the scalability testing: http://bit.do/vaadin-gatling http://bit.do/vaadin-jmeter

Caution! Use unique ids for components!


Server-side interceptor for recording Push WebSocket communication. You can use recorded requests e.g. for scalability testing a Vaadin application with JMeter. See also (https://github.com/johannest/JMeter-WebSocketSampler) for a customized WebSocketSampler plugin for JMeter.
