createExecutorService

@API(status=EXPERIMENTAL,
     since="1.3")
protected HierarchicalTestExecutorService createExecutorService(ExecutionRequest request)

Create the executor service to use for executing the supplied request.

An engine may use the information in the supplied request such as the contained configuration parameters to decide what kind of service to return or how to configure it.

By default, this method returns an instance of SameThreadHierarchicalTestExecutorService.

Parameters:

request - the request about to be executed

Since:

1.3

createExecutionContext

protected abstract C createExecutionContext(ExecutionRequest request)

Create the initial execution context for executing the supplied request.

Parameters:

request - the request about to be executed

Returns:

the initial context that will be passed to nodes in the hierarchy
