/**
 * Provides some helper methods for testing fieldapi integration into views.
 *
 * @todo Test on a generic entity not on a node. What has to be tested:
 *   - Make sure that every wanted field is added to the according entity type.
 *   - Make sure the joins are done correctly.
 *   - Use basic fields and make sure that the full wanted object is built.
 *   - Use relationships between different entity types, for example node and
 *     the node author(user).
