Usage

From source file:com.athena.meerkat.controller.web.provisioning.log.LogTailerListenerTest.java

@Test
public void testHandleString() {
    LogTailerListener listener = new LogTailerListener(new WebSocketSessionMock());

    // stupid executor impl. for demo purposes

    Executor executor = new Executor() {
