03-29复利计算单元测试

说明:之前用C语言写代码,现用java写代码。

 

场景分析,期待的返回值以及运行结果如下表:

注释:预期结果0.0,表示输入数据有误。即得不到正确的结果

其他计算功能测试与上述相似。

运行测试结果如下(部分):

 

 

 

测试程序代码如下(部分):

//用于测试单利计算获得利息
    public void testSimpleInteres() {
        SimpleInteres s = new SimpleInteres();
        Assert.assertEquals(102.0, s.getResult("100", "1", "2"),0.1);
        Assert.assertEquals(0.0, s.getResult("0", "1", "2"),0.1);
        Assert.assertEquals(0.0, s.getResult("asdf", "1", "2"),0.1);
        Assert.assertEquals(0.0, s.getResult("100", "-1", "2"),0.1);
    }
    //用于测试复利计算获得利息
    public void testCompoundInterest() {
        CompoundInterest s = new CompoundInterest();
        Assert.assertEquals(102.01, s.getResult("100", "1", "2"),0.1);
        Assert.assertEquals(0.0, s.getResult("0", "1", "2"),0.1);
        Assert.assertEquals(0.0, s.getResult("asdf", "1", "2"),0.1);
        Assert.assertEquals(0.0, s.getResult("100", "-1", "2"),0.1);
    }
    //用于测试计算本金(按复利)
    public void testGetPrincipal() {
        GetPrincipal s = new GetPrincipal();
        Assert.assertEquals(103.91, s.getResult("106", "1", "2"),0.1);
        Assert.assertEquals(0.0, s.getResult("0", "1", "2"),0.1);
        Assert.assertEquals(0.0, s.getResult("asdf", "1", "2"),0.1);
        Assert.assertEquals(0.0, s.getResult("100", "-1", "2"),0.1);
    }
