RenderIdempotencyChecker

object RenderIdempotencyChecker : WorkflowInterceptor(source)

Intercepts the render pass of the root workflow and runs it twice to ensure that well-written unit tests catch side effects being incorrectly performed directly in the render method.

The first render pass is the real one, the second one is a no-op and child workflow renderings will be played back, in order, to their renderChild calls.
