Interface GridTestRouter

All Known Implementing Classes:

GridTestRouterAdapter

public interface GridTestRouter

Optional router used to route individual tests to remote nodes for execution. Distributed JUnits can be instructed to use a specific implementation of this router in one of the following ways:

• By specifying router class name as GridTestVmParameters.GRIDGAIN_TEST_ROUTER VM parameter
• By specifying router class from GridifyTest.routerClass() annotation method.
• By setting it on test suite explicitely by calling GridJunit3TestSuite.setRouterClass(Class) method.

If not provided, then by default GridTestRouterAdapter is used which routes tests to grid nodes in round-robin fashion. Refer to GridTestRouterAdapter documentation for more information.

Method Summary

GridNode

route(Class<?> test, String name, Collection<GridNode> subgrid, UUID locNodeId) Routes a test to a specific node.

Method Detail

route

GridNode route(Class<?> test,
               String name,
               Collection<GridNode> subgrid,
               UUID locNodeId)

Routes a test to a specific node. This method is provided so subclasses could specify their own logic for routing tests. It should be useful when some test can only be run on a specific node or on a specific set of nodes.

By default tests are routed to grid nodes in round-robin fashion. Set GridTestVmParameters.GRIDGAIN_ROUTER_PREFER_REMOTE VM parameter to true to always route tests to remote nodes, assuming there are any. If there are no remote nodes, then tests will still execute locally even if this VM parameter is set.

Parameters:

test - Test class.

name - Test name.

subgrid - List of available grid nodes.

locNodeId - Local node ID.

Returns:

Node this test should execute on.
