> Key: SPARK-22045
> URL: https://issues.apache.org/jira/browse/SPARK-22045
> Project: Spark
> Issue Type: New Feature
> Components: Tests
> Affects Versions: 2.2.0
> Reporter: bluejoe
> Labels: netcat
>
> hi, all
> I have written a MockNetCat class, which help developers start a netcat
> programmatically, instead of manually launching
> {code:java}
> nc -lk 9999
> {code}
> command for test
> also I completed a MockNetCatTest class, a JUnit 4 test case which test
> MockNetCat
> use of MockNetCat is very simple, like:
> {code:java}
> var nc: MockNetCat = MockNetCat.start(9999);
> {code}
> this starts a NetCat server, and data can be generated using following code:
> {code:java}
> nc.writeData("hello\r\nworld\r\nbye\r\nworld\r\n");
> {code}
