复利计算—单元测试

 

1、手动测试：

2、代码测试：

 1 package invest;
 2 
 3 import static org.junit.Assert.*;
 4 import static org.hamcrest.CoreMatchers.*;
 5 import org.junit.Test;
 6 
 7 public class CompundingTest {

11     @Test
12     public void testCompunding() {
13         double F=Compunding.compunding(50000, 0.05, 10,1);
14         assertThat(F, is(81444.7313388721));
15     }
16 
17     @Test
