[英]How to test method without args using the spock framework
I can't figure out how to test this.我不知道如何测试这个。 Tell me please good literature or vebinar on this topic
请告诉我有关此主题的优秀文献或 vebinar
public InputMessenger getInputForMessengerFromConsole() {
String templateValue;
Map<String, String> valuesForTemplate = new HashMap<>();
try (Scanner scanner = new Scanner(System.in, Constant.CHARSET_NAME_UTF_8)) {
System.out.println(Constant.MESSAGE_INPUT_TEMPLATE);
templateValue = scanner.nextLine();
System.out.println(Constant.MESSAGE_NUMBER_OF_VALUES);
int numberOfValues = scanner.nextInt();
scanner.nextLine();
IntStream.range(0, numberOfValues).forEach(index -> {
System.out.println(Constant.MESSAGE_KEY + (index + Constant.INT_ONE) + Constant.COLON);
String key = scanner.nextLine();
System.out.println(Constant.MESSAGE_VALUE + (index + Constant.INT_ONE) + Constant.COLON);
String value = scanner.nextLine();
valuesForTemplate.put(key, value);
});
}
return new InputMessenger(templateValue, valuesForTemplate);
}
This is a draft (I didn't check it):这是草稿(我没看):
setup:
def originalIn = System.in
def originalOut = System.out
and: "Define new out:"
def out = new ByteArrayOutputStream()
System.setOut(new PrintStream(out))
and: "Define input data and specify in"
def input = "…input data for test…"
def in = new ByteArrayInputStream(input.getBytes())
System.setIn(in)
when:
def result = getInputForMessengerFromConsole()
then:
out.toString() == expectedOutput
and:
result == expectedResult
cleanup:
System.setOut(originalOut)
System.setIn(originalIn)
