Java类分别实现求三个整数中的最大数和最小数，并利用JUnit对其进行单元测试

最大数实现：

public class MaxNumber {

    public static int getMax(int a, int b, int c) {
        int max = a;
        if (b > max) {
            max = b;
        }
        if (c > max) {
            max = c;
        }
        return max;
    }
}

最小数实现：

public class MinNumber {

    public static int getMin(int a, int b, int c) {
        int min = a;
        if (b < min) {
            min = b;
        }
        if (c < min) {
            min = c;
        }
        return min;
    }
}

单元测试实现：

import org.junit.Assert;
import org.junit.Test;

public class NumberTest {

    @Test
    public void testMaxNumber() {
        Assert.assertEquals(3, MaxNumber.getMax(1, 2, 3));
        Assert.assertEquals(5, MaxNumber.getMax(3, 5, 4));
        Assert.assertEquals(10, MaxNumber.getMax(10, 8, 9));
    }

    @Test
    public void testMinNumber() {
        Assert.assertEquals(1, MinNumber.getMin(1, 2, 3));
        Assert.assertEquals(3, MinNumber.getMin(3, 5, 4));
        Assert.assertEquals(8, MinNumber.getMin(10, 8, 9));
    }
}
