使用UI Automation实现自动化测试--2

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 CalculateButton_Click(object sender, EventArgs e)
{
int num1 = 0;
int num2 = 0;
if (!int.TryParse(textBox1.Text.Trim(), out num1) || !int.TryParse(textBox2.Text.Trim(), out num2))
{
MessageBox.Show("Please input a correct number!");
return;
}
textBox3.Text = (num1 + num2).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

public static void TestWinFrom(int num1, int num2)
{
string winfromPath = @"C:\Users\v-lix\Documents\Visual Studio 2010\Projects\UIAutomationDemo\WinformForTesting\bin\Debug\WinformForTesting.exe";
Console.WriteLine("Begin WinForm UIAutomation test runn");
Console.WriteLine("Launching WinFormTest application");
Process p = Process.Start(winfromPath);
Thread.Sleep(TimeSpan.FromSeconds(2));
Console.WriteLine("Get desktop");
var desktop = AutomationElement.RootElement;

// Method 1 by windowhandle
AutomationElement testForm = AutomationElement.FromHandle(p.MainWindowHandle);

// Method 2 by name property
//PropertyCondition proCon = new PropertyCondition(AutomationElement.NameProperty,"TestForm1");
//testForm = desktop.FindFirst(TreeScope.Children,proCon);

if (testForm == null)
{
Console.WriteLine("Could find testform!");
return;
}

Console.WriteLine("Try to find the button control in testForm");
AutomationElement button = testForm.FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.NameProperty, "Calculate"));

Console.WriteLine("Try to find all the textbox in testform!");
AutomationElementCollection aeAllTextBoxes = testForm.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'");
//set textboxs' value by ValuePattern
ValuePattern vpTextBox1 = (ValuePattern)aeTextBox1.GetCurrentPattern(ValuePattern.Pattern);
vpTextBox1.SetValue(num1.ToString());
ValuePattern vpTextBox2 = (ValuePattern)aeTextBox2.GetCurrentPattern(ValuePattern.Pattern);
vpTextBox2.SetValue(num2.ToString());
Thread.Sleep(150);
Console.WriteLine("Clickinig on button1 Button.");
InvokePattern ipButton = (InvokePattern)button.GetCurrentPattern(InvokePattern.Pattern);
ipButton.Invoke();
Thread.Sleep(1000);

ValuePattern vpTextBox3 = (ValuePattern)aeTextBox3.GetCurrentPattern(ValuePattern.Pattern);
if (int.Parse(vpTextBox3.Current.Value.Trim()) != (num1 + num2))
{
Console.WriteLine("Failed");
}
else
{
Console.WriteLine("Pass");
}

Thread.Sleep(5000);
//close testform
WindowPattern wpCloseForm = (WindowPattern)testForm.GetCurrentPattern(WindowPattern.Pattern);
wpCloseForm.Close();
}
