@Test public void testCreateTextBox() throws IOException { String presentationId = this.createTestPresentation(); String pageId = this.createTestSlide(presentationId); BatchUpdatePresentationResponse response = this.snippets.createTextBoxWithText(presentationId, pageId); assertEquals(2, response.getReplies().size()); String boxId = response.getReplies().get(0).getCreateShape().getObjectId(); assertNotNull(boxId); }
