### Question:
NormalizeDateTimeLiteralsTransformer extends SimpleDMNTransformer<TestLab> { private void normalize(TLiteralExpression exp) { if (exp != null) { String newText = normalize(exp.getText()); exp.setText(newText); } } NormalizeDateTimeLiteralsTransformer();  NormalizeDateTimeLiteralsTransformer(BuildLogger logger); @Override DMNModelRepository transform(DMNModelRepository repository); @Override Pair<DMNModelRepository, List<TestLab>> transform(DMNModelRepository repository, List<TestLab> testCases);  }### Answer:
@Test public void testNormalize() { assertNull(transformer.normalize(null)); assertEquals("", transformer.normalize("")); assertEquals("date and time(\"1900-01-01T00:00:00Z\")", transformer.normalize("date and time(\"1899-12-31T19:00:00-0500\")")); assertEquals("time(\"00:00:00Z\")", transformer.normalize("time(\"T19:00:00-0500\")")); assertEquals("time(\"00:00:00Z\")", transformer.normalize("time(\"19:00:00-0500\")")); }
