[英]JUnit Test failing and not sure why
我对编写代码很陌生,我不是最好的,但我不明白为什么我的代码没有通过我设置的 JUnit 测试之一。
public class PA3Test {
public static void main(String[] args) {
}
public static int countMajority(int count0, int count1, int count2) {
int allVotes = (count0 + count1 + count2);
int halfVotes = (allVotes / 2);
int winner = 999;
if (count0 >= halfVotes) {
winner = 0;
} else {
winner = -1;
}
if (count1 >= halfVotes) {
winner = 1;
} else {
winner = -1;
}
return winner;
}
测试看起来像这样:
import junit.framework.TestCase;
public class PA3TestTest extends TestCase {
public static void testCountMajority() {
assertEquals("0th param should win:", 0,
PA3Test.countMajority(100, 50, 40));
assertEquals("1st param should win:", 1,
PA3Test.countMajority(50, 100, 40));
}
它应该返回 0 但它返回 -1。 任何帮助表示赞赏。
在你的第一次测试中,
所有投票数=190
半票数=95
count0 = 100 > 95,获胜者 = 0
计数 1 = 50 < 95,获胜者 = -1
public static int countMajority(int count0, int count1, int count2) { int allVotes = (count0 + count1 + count2); int halfVotes = (allVotes / 2); int winner = -1; if (count0 >= halfVotes) { winner = 0; } else if (count1 >= halfVotes) { winner = 1; } return winner; }
不知道为什么当你有 3 个计数时,你把它平均为 2。 但是根据您的问题陈述,这应该可以解决问题。
public static int countMajority(int count0, int count1, int count2) {
int allVotes = (count0 + count1 + count2);
int halfVotes = (allVotes / 2);
int winner = -1;
if (count0 >= halfVotes) {
winner = 0;
}
if (count1 >= halfVotes && count1 > count0) {
winner = 1;
}
return winner;
}
