7 Enhanced Browser Automation Tricks You Need to Know- Testing Framework

• Download full source code

Introduction

One of the common things between the fast and maintainable UI tests is the know-how of the automation engineer to use the automation framework correctly. A large part of it is how to handle the different browsers properly in various situations. In this article, part of the Testing Framework Series, I am going to share with you a couple of compelling features of this framework.

Browser Automation Tricks

1. Handle Logon Dialogs

Usually, it is not so trivial to automate similar to the above dialog. Through Testing Framework, you only need to add a LogonDialog instance to DialogMonitor via the AddDialog method. In the constructor of LogonDialog, specify the exact username and password. Then, you need only to navigate to the desired protected page. Also, you need to add a using statement to ArtOfTest.WebAii.Win32.Dialogs.

[TestMethod]
public void LogonDialog()
{
    // add using to ArtOfTest.WebAii.Win32.Dialogs
    manager.DialogMonitor.AddDialog(
    new LogonDialog(manager.ActiveBrowser, "<username>", "<password>", DialogButton.OK));
    manager.DialogMonitor.Start();

    // Navigate to a page that need a logon
    manager.ActiveBrowser.NavigateTo("<Exchange with the URL to LogOn>");
}

2. Http Proxy- Intercept RAW HTTP Traffic

Testing Framework includes the ArtOfTest.WebAii.Messaging.Http namespace. With it, you have the ability to intercept raw HTTP traffic under the cover. Using the HTTP proxy, you can intercept an HTTP request originating from the browser before it is sent to the web server and/or intercept HTTP responses coming from the web server just before they reach the browser and are rendered by it.

[TestInitialize]
public void TestInitialize()
{
    Settings mySettings = new Settings();
    mySettings.Web.DefaultBrowser = BrowserType.FireFox;
    mySettings.Web.UseHttpProxy = true;
    manager = new Manager(mySettings);
    manager.Settings.Web.RecycleBrowser = true;
    manager.Settings.Web.KillBrowserProcessOnClose = true;
    manager.Settings.AnnotateExecution = true;
    manager.Start();
    manager.LaunchNewBrowser();        
}

It is important to set the property UseHttpProxy to true, you can do it via code as shown above. Or you can configure it directly in your app.config.

<configuration>
  <configSections>
    <section name="WebAii.Settings" 
    type="ArtOfTest.WebAii.Core.SettingsConfigSectionHandler,ArtOfTest.WebAii"/>
    <section name="WebAii.Settings.Web" 
    type="ArtOfTest.WebAii.Core.WebSettingsConfigSectionHandler,ArtOfTest.WebAii"/>
    <section type="ArtOfTest.WebAii.Core.WpfSettingsConfigSectionHandler,ArtOfTest.WebAii"
    name="WebAii.Settings.Wpf"/>
  </configSections>
  <WebAii.Settings
                logLocation="F:\Log\"
                executionTimeout="30000"
                clientReadyTimeout="20000"
                queryEventLogErrorsOnExit="false"
                executionDelay="0"
                annotateExecution="true"
                annotationMode="All"
                logAnnotations="false"
                waitCheckInterval="633"
                createLogFile="true"
                Manager.Settings.Web.UseHttpProxy="true">
  </WebAii.Settings>
  <WebAii.Settings.Web baseUrl="http://automatetheplanet.com">
  </WebAii.Settings.Web>
</configuration>

You need to add Manager.Settings.Web.UseHttpProxy="true" to WebAii.Settings section.

[TestMethod]
public void InterceptRawHttpTraffic()
{
    ResponseListenerInfo responseListner = 
    new ResponseListenerInfo(AssertJavaScriptIsGZiped);
    manager.Http.AddBeforeResponseListener(responseListner);

    manager.ActiveBrowser.NavigateTo(
        "http://automatetheplanet.com/healthy-diet-menu-generator/");

    manager.Http.RemoveBeforeResponseListener(responseListner);
}

private void AssertJavaScriptIsGZiped(object sender, HttpResponseEventArgs e)
{
    Debug.WriteLine(String.Format("Request for {0}", e.Response.Request.RequestUri));
    if (e.Response.Headers["Content-Type"] != null &&
    e.Response.Headers["Content-Type"].Equals("application/javascript"))
    {
        Assert.AreEqual("gzip", e.Response.Headers["Content-Encoding"]);
    }
}

First, you need to create a response listener and pass to it the method that will assert the responses. In our case, I created logic to assert that every JavaScript file is GZiped. After that, you need to associate the created listener with the current Testing Framework manager via the AddBeforeResponseListener method. When you navigate to the desired URL, your handler method will be called for every request. Finally, you need to remove the listener.

3. Browser History

[TestMethod]
public void BrowserHistory()
{
    manager.ActiveBrowser.NavigateTo(
        "http://automatetheplanet.com/healthy-diet-menu-generator/");
    manager.ActiveBrowser.Refresh();

    Assert.AreEqual(
        "Healthy Diet Menu Generator - Automate The Planet",
        manager.ActiveBrowser.PageTitle);

    manager.ActiveBrowser.NavigateTo(
        "http://automatetheplanet.com/");
    manager.ActiveBrowser.GoBack();

    Assert.AreEqual(
        "Healthy Diet Menu Generator - Automate The Planet",
        manager.ActiveBrowser.PageTitle);

    manager.ActiveBrowser.GoForward();

    Assert.AreEqual(
        "Automate The Planet",
        manager.ActiveBrowser.PageTitle);
}

var newCookie = new System.Net.Cookie(
"AutomateThePlanet", 
"Rocks", 
"/",
"http://automatetheplanet.com");
manager.ActiveBrowser.Cookies.SetCookie(newCookie);

System.Net.CookieCollection siteCookies =
    manager.ActiveBrowser.Cookies.GetCookies("http://automatetheplanet.com");

manager.ActiveBrowser.Cookies.DeleteCookie(newCookie);

foreach (System.Net.Cookie cookie in siteCookies)
{
    manager.ActiveBrowser.Cookies.DeleteCookie(cookie);
}

[TestMethod]

    HtmlInputRadioButton coffeeRadioButton = 
        manager.ActiveBrowser.Find.ByExpression<htmlinputradiobutton>("value=^1 x Trenta");
    coffeeRadioButton.ScrollToVisible(ScrollToVisibleType.ElementTopAtWindowTop);
}</htmlinputradiobutton>

    manager.LaunchNewBrowser(BrowserType.InternetExplorer, true);            
    Browser internetExplorer = manager.ActiveBrowser;
    internetExplorer.NavigateTo(

    HtmlInputRadioButton coffeeRadioButton = 
    firefox.Find.ByExpression<HtmlInputRadioButton>("value=^1 x Trenta");
    coffeeRadioButton.ScrollToVisible(ScrollToVisibleType.ElementTopAtWindowTop);
            
    Browser firefox2 = manager.Browsers[0];
    firefox2.Window.SetFocus();

    internetExplorer.Window.SetFocus();

    firefox.Close(40);

    if (File.Exists(fileToDownload))
    {
        File.Delete(fileToDownload);
    }

    manager.ActiveBrowser.NavigateTo(
        "http://www.w3schools.com/tags/tryit.asp?filename=tryhtml5_a_download");
