### Question:
DecisionComponentsItemView implements DecisionComponentsItem.View { @Override public void setFile(final String file) { this.file.textContent = file; } @Inject  DecisionComponentsItemView(final HTMLImageElement icon,
                                      final @Named("h5") HTMLHeadingElement name,
                                      final HTMLParagraphElement file,
                                      final DMNShapeSet dmnShapeSet,
                                      final SessionManager sessionManager,
                                      final ShapeGlyphDragHandler shapeGlyphDragHandler,
                                      final Event<BuildCanvasShapeEvent> buildCanvasShapeEvent,
                                      final HTMLDivElement decisionComponentItem,
                                      final Event<NotificationEvent> notificationEvent,
                                      final ClientTranslationService clientTranslationService); @Override void init(final DecisionComponentsItem presenter); @Override void setIcon(final String iconURI); @Override void setName(final String name); @Override void setFile(final String file); @Override void setIsImported(final boolean imported); @EventHandler("decision-component-item") void decisionComponentItemMouseDown(final MouseDownEvent mouseDownEvent);  }### Answer:
@Test public void testSetFile() { final String file = "file"; this.file.textContent = "something"; view.setFile(file); assertEquals(file, this.file.textContent); }
