API TestAutomation(轻量级自动化测试)

 1。待测系统（SUT）

 

using System;

namespace Mathlib
...{
    public class Methods
    ...{
        public static int MethodSum(params int[] vals)
        ...{
            int sum=0;
            if (vals == null) return 0;
            for(int i=0;i<vals.Length;i++)
                sum+=vals[i];
            return sum;
        }
        
        public static double MethodAverage(params int[] vals)
        ...{
            double average=0.0;
            int sum=0;
            for(int i=0;i<vals.Length;i++)
                sum+=vals[i];
            average=sum/vals.Length;
            return average;
        }
    }
}

 

2。Program Apitest

 

using System;
using Mathlib;
using System.IO;
using System.Net.Mail;

namespace TestAutomation
...{

    /// Description of APITest.

问题：

1。文件路径参数化

2。处理“方法抛出异常”的情况

3。在Apitest中在测试用例失败时发送警告邮件
