复利计算的单元测试

此次测试只用两个单元作为例子

结果截图：

源代码：

public class testMoney {
public double danli(double P ,double i,double N ){
double M;
for (int j = 0; j < N; j++) {
         P = P * (1 + i);
         P = P + N;
     }
      M= Math.round((P - N) * 100) / 100.0;
return M;
 }
public static double moneyzz(double P, double i, double N, double T) {
double F;
for (int j = 0; j < N; j++) {
         P = P * (1 + i);
         P = P + T;
     }
     F = Math.round((P - T) * 100) / 100.0;
return F;
 }
}

public class testMoneyTest {

}

public class testMoneyTest2 {

@Test

boolean right = 32435.62 ==f;
        assertEquals(true,right);
}

}
