问题描述
我在这里遇到问题-我正在研究Fizz-Buzz-None。如果被3-Fizz，5-Buzz，3和5-FizzBuzz除以其他情况-无。我在IntliiJ终端中收到一条错误消息，提示“值应该不同。实际：无”。请告诉我我做错了什么:) 这是我的代码；
public class FizzBuzzNoneChecker {
public String checkIfFizz(int number) {
return "Fizz";
}
public String checkBuzz(int number) {
return "Buzz";
}
public String checkFizzBuzz(int number) {
return "FizzBuzz";
}
public String checkNone (int number) {
return "None";
}
}
import io.cucumber.java8.En;
import org.junit.Assert;
public class IsItFizzBuzzNonesteps implements En{
private String answer;
private int number;
public IsItFizzBuzzNonesteps () {
Given("Given number is 3",() -> {
// Write code here that turns the phrase above into concrete actions
this.number = 3;
});
Given("Given number is 6",() -> {
// Write code here that turns the phrase above into concrete actions
this.number = 6;
});
Given("Given number is 5",() -> {
// Write code here that turns the phrase above into concrete actions
this.number = 5;
});
Given("Given number is 10",() -> {
// Write code here that turns the phrase above into concrete actions
this.number = 10;
});
Given("Given number is 15",() -> {
// Write code here that turns the phrase above into concrete actions
this.number = 15;
});
Given("Given number is 30",() -> {
// Write code here that turns the phrase above into concrete actions
this.number = 30;
});
Given("Given number is 1",() -> {
// Write code here that turns the phrase above into concrete actions
this.number = 1;
});
Given("Given number is 91",() -> {
// Write code here that turns the phrase above into concrete actions
this.number = 91;
});
When("I ask about the password for the given number",() -> {
// Write code here that turns the phrase above into concrete actions
FizzBuzzNoneChecker fizzBuzzNoneChecker = new FizzBuzzNoneChecker();
this.answer = fizzBuzzNoneChecker.checkIfFizz(this.number);
this.answer = fizzBuzzNoneChecker.checkBuzz(this.number);
this.answer = fizzBuzzNoneChecker.checkFizzBuzz(this.number);
this.answer = fizzBuzzNoneChecker.checkNone(this.number);
});
Then("I should be told {string}",(String string) -> {
Assert.assertNotEquals(string,this.answer);
});
}
}
Feature: This is a game "Fizz-Buzz-None"
if a number is divisible by 5 & 3 - say "FizzBuzz",if by 3 - say "Fizz",if by 5 - say "Buzz"
in another case - say "None"
Scenario Outline: Answer the right word as a reaction to a given number
Given Given number is <number>
When I ask about the password for the given number
Then I should be told <answer>
Examples:
| number | answer |
| 3 | "Fizz" |
| 6 | "Fizz" |
| 5 | "Buzz" |
| 10 | "Buzz" |
| 15 | "FizzBuzz" |
| 30 | "FizzBuzz" |
| 1 | "None" |
| 91 | "None" |
因此，当我放入Assert.assertEquals（string，this.answer）;没有一个测试通过，AssertNotEquals-其中6个和2个失败。
解决方法
- 您的FizzBuzzNoneChecker方法实际上并未检查任何内容。每个方法始终返回其固定字符串，无论您提供哪个数字。您需要在此处添加一些逻辑，以检查数字是否可以被3或5整除，以确定要返回的字符串，例如
public String checkIfFizz(int number) {
if (number % 3 == 0) {
return "Fizz";
} else {
return "";
}
}
我实际上会在三元操作中执行此操作，该操作要短得多，但是我不知道您是否遇到过这些操作。
-
就您的代码而言，this.answer始终最终是checkNone（）的结果。您需要使用一系列if（）语句找出要返回的字符串，从而将四个检查方法组合为一个。以我从第1点开始的代码为起点，并扩展逻辑，直到它以正确的顺序涵盖四种可能的情况，以给出正确的响应。。
-
要从“给定...”输入中提取数字，由于输入显然总是遵循该格式，因此请查看https://docs.oracle.com/javase/8/docs/api/index.html中的子字符串。
-
您的输入仅会是这些值之一，还是您需要考虑用户可能想知道42的可能性？
