使用UI Automation实现自动化测试--2

 

      本文通过一个实例来介绍怎样使用UI Automation实现软件的自动化测试。

1. 首先建立一个待测试的winform程序，即UI Automation的服务端。

 

下面是button事件处理程序。

 

private void button1_Click(object sender, EventArgs e)

{

     int i = int.Parse(textBox1.Text);

     int j = int.Parse(textBox2.Text);

     textBox3.Text = (i + j).ToString();

}

2. 建立一个测试程序，做UI Automaion的客户端。

添加引用：UIAutomationClient.dll 和 UIAutomationTypes.dll
