protected function NodePageCacheTest::testNodeUpdateInsertCache

Test node update and insert with entity cache.

Make sure that creating a new node does not affect existing entity cache records, and updating a node only acts on the affected cid.

Tests for node.module.

NodePageCacheTest

Tests the cache invalidation of node operations.
