Example 21 with Diagram

use of org.eclipse.sirius.components.diagrams.Diagram in project sirius-components by eclipse-sirius.

the class UnsynchronizedDiagramTests method testUnsynchronizedRenderingOnNodeContainerAfterDeletion.

/**
 * This very simple test will validate that we can add and remove an unsynchronized node thanks to a
 * ViewCreationRequest/ViewDeletionRequest on a node container. We will test the following sequence of events:
 *
 * <ul>
 * <li>render the diagram with two nodes (the first is unsynchronized, the second is synchronized)</li>
 * <li>create a new node thanks to a ViewCreationRequest during a refresh diagram</li>
 * <li>delete the node thanks to a ViewDeletionRequest during a refresh diagram: no child nodes should be visible on
 * the first unsynchronized node children</li>
 * </ul>
