### Question:
Snippets { public String createPresentation(String title) throws IOException { Slides slidesService = this.service; Presentation presentation = new Presentation() .setTitle(title); presentation = slidesService.presentations().create(presentation) .setFields("presentationId") .execute(); System.out.println("Created presentation with ID: " + presentation.getPresentationId()); return presentation.getPresentationId(); } Snippets(Slides service, Drive driveService, Sheets sheetsService); String createPresentation(String title); String copyPresentation(String presentationId, String copyTitle); BatchUpdatePresentationResponse createSlide(String presentationId); BatchUpdatePresentationResponse createTextBoxWithText(
            String presentationId, String slideId); BatchUpdatePresentationResponse createImage(String presentationId,
                                                       String slideId,
                                                       GoogleCredential credential); List<BatchUpdatePresentationResponse> textMerging(
            String templatePresentationId, String dataSpreadsheetId); BatchUpdatePresentationResponse imageMerging(String templatePresentationId,
                                                        String imageUrl,
                                                        String customerName); BatchUpdatePresentationResponse simpleTextReplace(
            String presentationId, String shapeId, String replacementText); BatchUpdatePresentationResponse textStyleUpdate(String presentationId, String shapeId); BatchUpdatePresentationResponse createBulletedText(String presentationId,
                                                              String shapeId); BatchUpdatePresentationResponse createSheetsChart(
            String presentationId, String pageId, String spreadsheetId, Integer sheetChartId); BatchUpdatePresentationResponse refreshSheetsChart(
            String presentationId, String presentationChartId);  }### Answer:
@Test public void testCreatePresentation() throws IOException { String presentationId = this.snippets.createPresentation("Title"); assertNotNull(presentationId); this.deleteFileOnCleanup(presentationId); }
