From 66ea26b1bc7bbc8d54a3498dbd3d0919c4712fa8 Mon Sep 17 00:00:00 2001 From: Marek Gradzki Date: Tue, 26 Jul 2016 15:28:22 +0200 Subject: VPP-205: jvpp plugin support. Splits jvpp into two jars jvpp-registry.jar - base jvpp functionality jvpp-core.jar - Java wrapper for vpe.api Plugins can be generated the same way jvpp-core.jar is.

-This package contains basic tests for jvpp. To run the tests:
-
-- Make sure VPP is running
-- From VPP's build-root/ folder execute:
-  - sudo java -cp build-vpp-native/vpp-api/java/jvpp-16.09.jar org.openvpp.jvpp.test.[test name]
-
-Available tests:
-ControlPingTest - Simple test executing a single control ping using low level JVpp APIs
-CallbackApiTest - Similar to ControlPingTest, invokes more complex calls (e.g. interface dump) using low level JVpp APIs
-CallbackNotificationApiTest - Tests interface notifications using low level JVpp APIs
-FutureApiTest - Execution of more complex calls using Future based JVpp facade
-FutureApiNotificationTest - Tests interface notifications using Future based JVpp facade
-CallbackJVppFacadeTest - Execution of more complex calls using Callback based JVpp facade
-CallbackJVppFacadeNotificationTest - Tests interface notifications using Callback based JVpp facade
-L2AclTest - Tests L2 ACL creation
-CreateSubInterfaceTest - Tests sub-interface creation
-OnErrorCallbackTest - simple test failing with onError
