在目前進行軟件測試時,都或多或少的引入了自動化測試的概念,而且市面上也有好多軟件自動化方面相關的工具,比如QTP,比如LoadRunner,但是這些工具要么售價不菲,要么對某些方面功能支持的不夠全面,那么我們在引入軟件自動化測試時,都需要考慮哪些方面呢?當然是最符合自己項目的工具最合適,同時費用也比較低,那么除了市面上這些商業軟件外,還有沒有哪些方法可以自己動手來做軟件的自動化測試呢?答案是肯定的.
????? 本文將介紹實現軟件自動化測試其中一種測試方法------UIAutomation技術,當然,此種方法僅限于對.Net軟件使用.

????? 反射技術具體是什么原理,本文將不做任何介紹,大家可以去網上搜索一下,有很多這方面的文章介紹,本文只介紹如何使用UIAutomation技術進行.NET軟件的UI界面的自動化測試.

????? 廢話少說,多做實事!(本文所有代碼均在VS2008環境下測試通過)

????? 一. 創建待測試程序

????????? 1. 啟動VS2008,建立一個C#的WinForm工程,并將工程文件名命名為AUT(Application Under Test)

????????? 2. 創建的Form上的按鈕布局,如下圖所示

????????? 3. 一個菜單(包含一個以及菜單File以及一個二級菜單Exit),一個TextBox,一個ComboBox,一個Button以及一個ListBox

? ? ? ? private System.Windows.Forms.MenuStrip menuStrip1;
private System.Windows.Forms.ToolStripMenuItem fileToolStripMenuItem;
private System.Windows.Forms.ToolStripMenuItem exitToolStripMenuItem;
private System.Windows.Forms.TextBox textBox1;
private System.Windows.Forms.ComboBox comboBox1;
private System.Windows.Forms.Button button1;
private System.Windows.Forms.ListBox listBox1;
????????????? 4. 給Button按鈕添加一個消息響應函數????

? ? ? ?private void button1_Click(object sender, EventArgs e)
{
string tb = textBox1.Text;
string cb = comboBox1.Text;
if (tb == cb)
{
listBox1.Items.Add("Result is a tie");
}
else if (tb == "paper" && cb == "rock" ||
tb == "rock" && cb == "scissors" ||
tb == "scissors" && cb == "paper")
{
listBox1.Items.Add("The TextBox wins");
}
else
{
listBox1.Items.Add("The ComboBox wins");
}
}
?????????? 5. 給Exit菜單添加一個消息響應函數???????
? ? ? ? private void exitToolStripMenuItem_Click(object sender, EventArgs e)
{
Application.Exit();
}
??????? 6.給ComboBox控件添加三個Item,分別為paper,rock,scissions
??????? 7. 編譯待測試程序,生成文件名為AUT.exe的待測試程序

??? 二. 創建測試程序??
??????? 1. 啟動VS2008,創建一個C#控制臺程序,并命名為AutomationUITest

??????? 2. 在引用中添加以下三個類: UIAutomationClient, UIAutomationClientsideProviders以及UIAutomationTypes

??????? 3. 在工程中添加以下using語句

? ? ? ?using System;
? ? ? ?using System.Windows.Automation;
? ? ? ?using System.Threading;
? ? ? ?using System.Diagnostics;
? ? ? ?using System.IO;
??????? 4. 定義啟動測試程序以及獲取窗體句柄的函數

SetComboBoxItemData(cbh, "rock");
Console.WriteLine("\nPush Mouse Left button");
ButtonLeftClick(bth);
string result = GetListBoxItemName(lbh, 0);
if (result == "The TextBox wins")
{
Console.WriteLine("\nTest seceions = PASS");
}
else
{
Console.WriteLine("\nTest seceions = Failed");
}
Console.WriteLine("\nGet Menu Handle");
AutomationElement mbh = GetMenuBarHandle(mwh, "menuStrip1");
Console.WriteLine("Menu Handle: " + mbh.Current.NativeWindowHandle.ToString());
string[] strTitle = { "File", "Exit", "" };
Console.WriteLine("\nClose Application Under Test in 3 Seconds....");
Thread.Sleep(3000);
SelectMenuBarItem(mbh, strTitle);
Console.ReadLine();
}
catch (System.Exception ex)
{
Console.WriteLine("\nError msg: " + ex.Message);
}
}
??????? 11.? 編譯測試程序,OK,大功告成
