WaitN中Alert,Confirm,FileUpload对话框使用
在自动化测试中，这三种对话框是相当常见：
下面的测试环境:
Win7 Vs2010 WaintN2.1 IE9
首先以管理员权限启动Vs2010，创建一个默认的Web项目及其测试项目，如下所示： 
1、confirm对话框使用
我们这里面测试的是asp.net Ajax控件
打开default.apsx,加入如下内容：
1: <asp:UpdatePanel ID="UpdatePanel1" runat="server">
2: <ContentTemplate>
3: <fieldset>
4: <legend>异步获取时间测试，并且使用弹出对话框进行确认</legend>
5: <hr />
6: 当前时间：<asp:Label ID="lblDate" runat="server"></asp:Label><asp:Button ID="btnGetDate"
7: runat="server" Text="获取当前时间" OnClientClick="return confirm('获取当前时间吗？');" OnClick="btnGetDate_Click" />
8: </fieldset>
9: </ContentTemplate>
10: </asp:UpdatePanel>
后台代码，如下：
1: protected void btnGetDate_Click(object sender, EventArgs e)
2: {
3: this.lblDate.Text = DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss");
4: }
实现的功能就是，通过异步的方式获取服务器的当前时间，在调用服务器前会询问用户是否获取服务器的当前时间，
对于处理Confirm对话框，先对浏览器加入如下扩展方法：
1: public static void CaptureConfirmDialog(this Browser browser, Action<ConfirmDialogHandler> operation, bool isOk, int waitTimeInSeconds)
2: {
3: var handler = new ConfirmDialogHandler();
4: using (new UseDialogOnce(browser.DialogWatcher, handler))
5: {
6: operation(handler);
7: if (waitTimeInSeconds > 0)
8: handler.WaitUntilExists(waitTimeInSeconds);
9: else
10: handler.WaitUntilExists();
11:
12: if (handler.Exists())
13: if (isOk)
14: handler.OKButton.Click();
15: else
16: handler.CancelButton.Click();
17:
18: browser.WaitForComplete();
19: }
20: }
21:
22: public static void CaptureConfirmDialog(this Browser browser, Action<ConfirmDialogHandler> operation, bool isOk)
23: {
24: CaptureConfirmDialog(browser, operation, isOk, 0);
25: }
测试代码如下：
1: [TestMethod]
2: public void TestConfirmText()
3: {
4: using (IE ie = GetIE())
5: {
6: Span span = ie.Span(c => c.Id.EndsWith("lblDate"));
7: string str = span.Text;
8: Button btn = ie.Button(c => c.Id.EndsWith("btnGetDate"));//点击id为"su"的按钮,就是百度的搜索按钮
9: ie.CaptureConfirmDialog(c => btn.ClickNoWait(), true);
10: span = ie.Span(c => c.Id.EndsWith("lblDate"));
11:
12: Assert.AreNotEqual(str, span.Text);
13: str = span.Text;
14: ie.WaitForComplete();
15: ie.CaptureConfirmDialog(c => btn.ClickNoWait(), false);
16:
17: span = ie.Span(c => c.Id.EndsWith("lblDate"));
18: Assert.AreEqual(str, span.Text);
19: str = span.Text;
20:
21:
22: ie.CaptureConfirmDialog(c => btn.ClickNoWait(), true);
23:
24: span = ie.Span(c => c.Id.EndsWith("lblDate"));
25: Assert.AreNotEqual(str, span.Text);
26: }
27: }
测试结果：
2、Alert对话框使用
在default.apsx页面中，加入如下内容：
1: <asp:UpdatePanel ID="UpdatePanel2" runat="server">
2: <ContentTemplate>
3: <fieldset>
4: <legend>Alert对话框测试</legend>
5: <hr />
6: <asp:Button ID="btnAlert" runat="server" OnClientClick="javascript:window.alert('弹出窗体。');return false;"
7: Text="显示Alert" />
8: </fieldset>
9: </ContentTemplate>
10: </asp:UpdatePanel>
同样，也加入如下扩展方法：
1: public static void CaptureAlertDialog(this Browser browser, Action<AlertDialogHandler> operation, int waitTimeInSeconds)
2: {
3: var handler = new AlertDialogHandler();
4: using (new UseDialogOnce(browser.DialogWatcher, handler))
5: {
6: operation(handler);
7: if (waitTimeInSeconds > 0)
8: handler.WaitUntilExists(waitTimeInSeconds);
9: else
10: handler.WaitUntilExists();
11:
12: if (handler.Exists())
13: handler.OKButton.Click();
14:
15: browser.WaitForComplete();
16: }
17: }
18: public static void CaptureAlertDialog(this Browser browser, Action<AlertDialogHandler> operation)
19: {
20: CaptureAlertDialog(browser, operation, 0);
21: }
测试代码如下：
1: [TestMethod]
2: public void TestAlertText()
3: {
4: using (IE ie = GetIE())
5: {
6: Button btn = ie.Button(c => c.Id.EndsWith("btnAlert"));
7: ie.CaptureAlertDialog(obj => btn.ClickNoWait());
8: }
9: }
测试结果：
3、FileUpload使用
在default.aspx中加入如下内容：
1: <asp:UpdatePanel ID="UpdatePanel4" runat="server">
2: <ContentTemplate>
3: <fieldset>
4: <legend>文件上载测试</legend>
5: <hr />
6: 文件名：<asp:FileUpload ID="fuLoadFile" runat="server" /><asp:Button ID="btnUpload" runat="server"
7: Text="上传" OnClick="btnUpload_Click" /><br />
8: <asp:Label ID="lblInfo" runat="server"></asp:Label>
9: </fieldset>
10: </ContentTemplate>
11: <Triggers>
12: <asp:PostBackTrigger ControlID="btnUpload" />
13: </Triggers>
14: </asp:UpdatePanel>
后台代码如下：
1: protected void btnUpload_Click(object sender, EventArgs e)
2: {
3: if(fuLoadFile.HasFile)
4: {
5: lblInfo.Text = "上载成功。";
6: }
7: else
8: {
9: lblInfo.Text = "上载失败";
10: }
11: }
测试代码如下：
1: [TestMethod]
2: public void TestFileUpload()
3: {
4: using (IE ie = GetIE())
5: {
6:
7: Button btn = ie.Button(c => c.Id.EndsWith("btnUpload"));
8: FileUpload fileUpload = ie.FileUpload(c => c.Id.EndsWith("fuLoadFile"));
9: fileUpload.Set("E:\\taobao.txt");
10: btn.Click();
11: ie.WaitForComplete();
12: var span = ie.Span(c => c.Id.EndsWith("lblInfo"));
13: Assert.AreEqual("上载成功。", span.Text);
14: }
15: }
测试结果：
测试完整代码：
1: [TestClass]
2: public class WaitNTest
3: {
4: private IE GetIE(string url)
5: {
6: IE ie = new IE(url);
7: ie.AutoClose = true;
8: return ie;
9: }
10:
11: private IE GetIE()
12: {
13: return GetIE("http://localhost:10195/Default.aspx");
14: }

31: using (IE ie = GetIE())
32: {
33: Span span = ie.Span(c => c.Id.EndsWith("lblDate"));
34: string str = span.Text;
35: Button btn = ie.Button(c => c.Id.EndsWith("btnGetDate"));//点击id为"su"的按钮,就是百度的搜索按钮
36: ie.CaptureConfirmDialog(c => btn.ClickNoWait(), true);
37: span = ie.Span(c => c.Id.EndsWith("lblDate"));

63: FileUpload fileUpload = ie.FileUpload(c => c.Id.EndsWith("fuLoadFile"));
64: fileUpload.Set("E:\\taobao.txt");
65: btn.Click();
66: ie.WaitForComplete();
67: var span = ie.Span(c => c.Id.EndsWith("lblInfo"));
68: Assert.AreEqual("上载成功。", span.Text);
69: }
