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

using System;
using System.Diagnostics;
using System.Threading;
using System.Windows.Automation.Provider;
using System.Windows.Automation.Text;
using System.Windows.Automation;

namespace UIAutomationTest
{
class Program
{
static void Main(string[] args)
{
try
{
Console.WriteLine("/nBegin WinForm UIAutomation test run/n");
// launch Form1 application
// get refernce to main Form control
// get references to user controls
// manipulate application
// check resulting state and determine pass/fail

Console.WriteLine("/nBegin WinForm UIAutomation test run/n");
Console.WriteLine("Launching WinFormTest application");
//启动被测试的程序
Process p = Process.Start(@"E:/Project/WinFormTest/WinFormTest/bin/Debug/WinFormTest.exe");

//自动化根元素
AutomationElement aeDeskTop = AutomationElement.RootElement;

Thread.Sleep(2000);
AutomationElement aeForm = AutomationElement.FromHandle(p.MainWindowHandle);
//获得对主窗体对象的引用，该对象实际上就是 Form1 应用程序(方法一)
//if (null == aeForm)
//{
//    Console.WriteLine("Can not find the WinFormTest from.");
//}

//获得对主窗体对象的引用，该对象实际上就是 Form1 应用程序(方法二)
int numWaits = 0;
do
{
Console.WriteLine("Looking for WinFormTest……");
//查找第一个自动化元素
aeForm = aeDeskTop.FindFirst(TreeScope.Children, new PropertyCondition(
AutomationElement.NameProperty, "Form1"));
++numWaits;
Thread.Sleep(100);
} while (null == aeForm && numWaits < 50);
if (null == aeForm)
throw new NullReferenceException("Failed to find WinFormTest.");
else
Console.WriteLine("Found it!");

Console.WriteLine("Finding all user controls");
//找到第一次出现的Button控件
AutomationElement aeButton = aeForm.FindFirst(TreeScope.Children,
new PropertyCondition(AutomationElement.NameProperty, "button1"));

//找到所有的TextBox控件
AutomationElementCollection aeAllTextBoxes = aeForm.FindAll(TreeScope.Children,
new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Edit));

// 控件初始化的顺序是先初始化后添加到控件
// this.Controls.Add(this.textBox3);
// this.Controls.Add(this.textBox2);
// this.Controls.Add(this.textBox1);

AutomationElement aeTextBox1 = aeAllTextBoxes[2];
AutomationElement aeTextBox2 = aeAllTextBoxes[1];
AutomationElement aeTextBox3 = aeAllTextBoxes[0];

Console.WriteLine("Settiing input to '30'");
//通过ValuePattern设置TextBox1的值
ValuePattern vpTextBox1 = (ValuePattern)aeTextBox1.GetCurrentPattern(ValuePattern.Pattern);
vpTextBox1.SetValue("30");
Console.WriteLine("Settiing input to '50'");
//通过ValuePattern设置TextBox2的值
ValuePattern vpTextBox2 = (ValuePattern)aeTextBox2.GetCurrentPattern(ValuePattern.Pattern);
vpTextBox2.SetValue("50");
Thread.Sleep(1500);
Console.WriteLine("Clickinig on button1 Button.");
//通过InvokePattern模拟点击按钮
InvokePattern ipClickButton1 = (InvokePattern)aeButton.GetCurrentPattern(InvokePattern.Pattern);
ipClickButton1.Invoke();
Thread.Sleep(1500);

//验证计算的结果与预期的结果是否相符合
Console.WriteLine("Checking textBox3 for '80'");
TextPattern tpTextBox3 = (TextPattern)aeTextBox3.GetCurrentPattern(TextPattern.Pattern);
string result = tpTextBox3.DocumentRange.GetText(-1);//获取textbox3中的值
//获取textbox3中的值
//string result = (string)aeTextBox2.GetCurrentPropertyValue(ValuePattern.ValueProperty);
if ("80" == result)
{
Console.WriteLine("Found it.");
Console.WriteLine("TTest scenario: *PASS*");
}
else
{
Console.WriteLine("Did not find it.");
Console.WriteLine("Test scenario: *FAIL*");
}

Console.WriteLine("Close application in 5 seconds.");
Thread.Sleep(5000);
//实现关闭被测试程序
WindowPattern wpCloseForm = (WindowPattern)aeForm.GetCurrentPattern(WindowPattern.Pattern);
wpCloseForm.Close();

Console.WriteLine("/nEnd test run/n");
}
catch (Exception ex)
{
Console.WriteLine("Fatal error: " + ex.Message);
}
}
}

MS提供的控件Pattern

DockPattern ExpandCollapsePattern
GridPattern GridItemPattern
InvokePattern MultipleViewPattern
RangeValuePattern ScrollPattern
ScrollItemPattern SelectionPattern
SelectionItemPattern TablePattern
TableItemPattern TextPattern
TogglePattern TransformPattern
ValuePattern WindowPattern
