All Implemented Interfaces:

TestRule

public final class EventLoopGroupRule
extends ExternalResource

A TestRule that provides an EventLoopGroup. For example:

 > public class MyTest {
 >     @ClassRule
 >     public static final EventLoopGroupRule eventLoopGroup = new EventLoopGroupRule(4);
 >
 >     @Test
 >     public void test() {
 >         ClientFactory f = ClientFactory.builder()
 >                                        .workerGroup(eventLoopGroup.get())
 >                                        .build();
 >         ...
 >     }
