MyDocumentModel { public String getFullTokenAtPosition(Position position) { Line route = getLine(position.getLine()); if (route == null) { return ""; } return retrieveToken(position, route); } MyDocumentModel(String text, AnalysisResult analysisResult);  MyDocumentModel(String text); Line getLine(int number); String getTokenBeforePosition(Position position); String getFullTokenAtPosition(Position position);  }### Answer:
@Test void testGetTokenInvalidPositionWithCorrectLine() { Position pos = new Position(3, -19); assertEquals("", model.getFullTokenAtPosition(pos)); }
