hi, all I have written a MockNetCat class, which help developers start a netcat programmatically, instead of manually launching nc -lk 9999 command for test developers can start a mock NetCat server in test cases and send data to the server (simulating user input text in the nc shell)
is this feature ok to create a PR to flink? use of MockNetCat is very simple, like: var nc: MockNetCat = MockNetCat.start(9999); this starts a NetCat server, and data can be generated using following code: nc.writeData("hello\r\nworld\r\nbye\r\nworld\r\n"); also i posted a JIRA issue at https://issues.apache.org/jira/browse/FLINK-7827 while got no reply:(
