@Test public void testTextMerge() throws IOException { List<BatchUpdatePresentationResponse> responses = this.snippets.textMerging(TEMPLATE_PRESENTATION_ID, DATA_SPREADSHEET_ID); for (BatchUpdatePresentationResponse response: responses) { String presentationId = response.getPresentationId(); assertNotNull(presentationId); assertEquals(3, response.getReplies().size()); int numReplacements = 0; for (Response resp : response.getReplies()) { numReplacements += resp.getReplaceAllText().getOccurrencesChanged(); } assertEquals(4, numReplacements); this.deleteFileOnCleanup(presentationId); } }
