### Question:
BnList extends JList implements View<IListPM>, ModelSubscriber { public void setPath(Path path) { this.link.setPath(path); } BnList(); IListPM getPresentationModel(); void setPresentationModel(IListPM newModel); IModelProvider getModelProvider(); void setModelProvider(IModelProvider provider); Path getPath(); void setPath(Path path); CellConfig getCellConfig(); void setCellConfig(CellConfig cellConfig);  }### Answer:
@Test public void testSetPath() { this.provider.setPresentationModel(this.model); this.list.setModelProvider(provider); assertEquals("listCell.getVisibleRowCount()", 0, list.getModel().getSize()); this.list.setPath(new Path("this.things")); this.list.setCellConfig(new CellConfig(new Path("this"))); assertEquals("listCell.getVisibleRowCount()", this.model.things.size(), list.getModel().getSize()); }
