@Test public void testGetImportedItemDefinitions() { final Map<Import, Definitions> importDefinitions = new HashMap<>(); final Import anImport = mock(Import.class); final Definitions definitions = mock(Definitions.class); final ItemDefinition itemDefinition1 = mock(ItemDefinition.class); final ItemDefinition itemDefinition2 = mock(ItemDefinition.class); final ItemDefinition itemDefinition3 = mock(ItemDefinition.class); final List<ItemDefinition> expectedItemDefinitions = asList(itemDefinition1, itemDefinition2, itemDefinition3); doReturn(expectedItemDefinitions).when(helper).getItemDefinitionsWithNamespace(definitions, anImport); importDefinitions.put(anImport, definitions); final List<ItemDefinition> actualItemDefinitions = helper.getImportedItemDefinitions(importDefinitions); assertEquals(expectedItemDefinitions, actualItemDefinitions); }
