### Question:
ConditionParser { public Condition parse() throws ParseException { parseReturnSentence(); functionName = parseFunctionName(); functionName = functionName.substring(KIE_FUNCTIONS.length()); List<FunctionDef> functionDefs = FunctionsRegistry.getInstance().getFunctions(functionName); if (functionDefs.isEmpty()) { throw new ParseException(errorMessage(FUNCTION_NAME_NOT_RECOGNIZED_ERROR, functionName), parseIndex); } ParseException lastTryException = null; for (FunctionDef functionDef : functionDefs) { try { reset(); return parse(functionDef); } catch (ParseException e) { lastTryException = e; } } throw lastTryException; } ConditionParser(String expression); Condition parse(); static final String KIE_FUNCTIONS; }### Answer:
@Test public void testWhiteSpaces() throws Exception { Condition expectedCondition = new Condition("between", Arrays.asList("someVariable", "value1", "value2")); char[] whiteSpaceChars = {'\n', '\t', ' ', '\r'}; String conditionTemplate = "%sreturn%sKieFunctions.between(%ssomeVariable%s,%s\"value1\"%s,%s\"value2\"%s)%s;"; String condition; for (char whiteSpace : whiteSpaceChars) { condition = String.format(conditionTemplate, whiteSpace, whiteSpace, whiteSpace, whiteSpace, whiteSpace, whiteSpace, whiteSpace, whiteSpace, whiteSpace); assertEquals(expectedCondition, new ConditionParser(condition).parse()); } conditionTemplate = "%sreturn%sKieFunctions.between(%ssomeVariable%s.%ssomeMethod%s(%s)%s,%s\"value1\"%s,%s\"value2\"%s)%s;"; for (char whiteSpace : whiteSpaceChars) { condition = String.format(conditionTemplate, whiteSpace, whiteSpace, whiteSpace, whiteSpace, whiteSpace, whiteSpace, whiteSpace, whiteSpace, whiteSpace, whiteSpace, whiteSpace, whiteSpace, whiteSpace); expectedCondition = new Condition("between", Arrays.asList("someVariable.someMethod()", "value1", "value2")); assertEquals(expectedCondition, new ConditionParser(condition).parse()); } }
