I'm getting started coding tests using watiN and I'm having trouble simulating a user pressing a key when a SelectList is in focus. This is to test that a client-side JavaScript function that is triggered by the OnKeyUp event on the SelectList runs correctly.
How can I simulate a user giving focus to the SelectList and pressing the 'o' key on their keyboard?
I'm using the latest WatiN release and am doing a C# unit test in VS2008. I've coded
ie = new IE(myTestPageURL);
SelectList mySelect = ie.SelectLists[0];
mySelect.Focus();
mySelect.KeyPress('o');
Assert.IsTrue(mySelect.SelectedItem != null);
My select list has an option in it called "One", so pressing the 'o' key should result in it being the selected item. However, nothing is happening when the keyPress call is made except that the SelectList loses focus, and my test fails.
I'm guessing you have, but have you looked into
SelectList.SelectByValue
?
It would,seemingly, make your tests more repeatable since you could add anything to your list and have it still work. Also, your tests should still break if your selectlist items fail to populate (for whatever reason). Selecting by value adds more specificity to your tests rather than just having them select the first item beginning with 'o'.
Fwiw is what we use in production at my current place of employment.
Thank you, Gram. Using Element.FireEvent works for me. For anyone who's interested, the code ended up looking like this.
[TestMethod]
public void KeyboardSelection_OptionMatches()
{
ie = new IE("http://localhost:7561/WebSite2/Default.aspx");
SelectList mySelect = ie.SelectLists[0];
mySelect.Focus();
NameValueCollection nvc = new NameValueCollection();
nvc.Add("charCode", ACharCode); //Constant for test - equals '65'
nvc.Add("keyCode", ACharCode);
// this should select the "A" option
mySelect.FireEvent("onkeydown", nvc);
// this should move the selected option to "aardvark"
mySelect.FireEvent("onkeydown", nvc);
string selectedValue = mySelect.SelectedItem.ToLower();
ie.Close();
Assert.AreEqual(selectedValue, "aardvark");
}
}
I use SelectList.Select() to select my dropdown items.
But since you want to test the javascript event, you might want to try to explicitly invoke the javascript event with Element.FireEvent().
Also, the TextField object has a TypeText() method that simulates a user typing and triggers all the events involved, but I didn't see a TypeText for SelectList. Maybe you can find a solution with the two.
I had a similar problem with a calendar control and resolved it by invoking the .Blur() method/event on the control.

I am getting crazy with a problem that I found when executing a Visual Studio Coded UI Test.
The scenario is as follows.
I recorded a Coded UI Tests that do the following steps in a Web Application (Microsoft Dynamics CRM 2011):
Login into an application
Navigate into a page
On the page set the selected value of a html combobox
The test is able to do all those steps without a problem, even selecting the value in the combobox.
The web application have a piece of Javascript that is executed when the selected item changes.
if one of the values is selected then an alert message is presented to the user and the application will set the selected item to a default one!
The javascript code look like this:
switch (Xrm.Page.getAttribute("status").getValue()) {
case 3: //Authorised
alert("Please use the method XPTO to update the record status to Authorised!");
Xrm.Page.getAttribute("status").setValue(1);
Xrm.Page.getControl("tatus").setFocus(true);
return false;
The UI Test method that is performing the change in the combobox is as follows:
/// <summary>
/// Select a value in the Status dropdown box
/// </summary>
public void SelectStatus()
{
#region Variable Declarations
HtmlComboBox uIStatusComboBox = this.UIHttpsappWindow200.UIModuleUITEDocument5.UIWorkplaceDashboardsFrame.UIModuleUITEDocument.UIStatusComboBox;
// Select 'Authorised' in 'Status' combo box
uIStatusComboBox.SelectedItem = this.SelectStatus_SPParams.UIStatusComboBoxSelectedItem;
}
The test method is able to change the value in the combobox, and an alert message is displayed to the user. However this part of the code uIStatusComboBox.SelectedItem = this.SelectStatus_SPParams.UIStatusComboBoxSelectedItem;
never returns and the test just hangs there until it timeouts!
I have no ideia how to work arround this issue! I was thinking that maybe the problem could be in the fact that we have javascript code that is executed after the alert is displayed to the user. I changed the JS so that the alert message is the last thing to be displayed but it also didn´t help!
I also noticed that if I click Ok on the alert message the test Pass!
If I select other value that dont trigger any JS the test also Pass!
Does anyone have any idea about this issue?
Edit 1:
I noticed another thing, I can use the BrowserWindow object to send a JS script to the browser. If I try to create an alert message the call also gets blocked until I click on the Ok button, on the alert!
BrowserWindow bw = BrowserWindow.Locate("My window");
bw.ExecuteScript("alert('This is just a simple alert.');");
The ExecuteScript statement also gets blocked until I click on the OK button!
This seems very very strange!
I believe I have found a workaround.
I was googling to find anything that could help me with this issue and I end up finding this question on StackOverflow Coded ui test - Select an item from a combobox without using mouse coordinates
I try to select the same item in the Dropdown without using the "SelectedItem" property of the HtmlComboBox element.
I try to use the keyboard to select the element in the dropdown box, first I click on the Dropdown and then I use the Down key and Enter key to select the element that I want:
public void SelectStatus_SP(string SelectedItem)
{
#region Variable Declarations
HtmlComboBox uIStatusComboBox = this.UIHttpsappWindow200.UIpopupUITEDocument5.UIWorkplaceDashboardsFrame.UIpopupUITEDocument.UIStatusComboBox;
#endregion
Mouse.Click(uIStatusComboBox);
Keyboard.SendKeys(uIStatusComboBox, "{Down}{Down}{Enter}", ModifierKeys.None);
}
In my case the element that I want to select is the 3rd one, so I go down 2 times and then hit enter on the element I want to select.
This workaround is not so good because if the element changes position I will select the worng one! But this was the only way I got for the test not to be stock in that part!
I wonder if anyone had a similar issue. Because to me this seems like a bug in the Coded UI Test engine, It doesn´t make any scence for the test to be stocked while the alert is not closed!
I am trying to build a test scenario for acceptance testing. In my scenario, I want to click on an non-editable input field to trigger a JqueryUI calendar, and then click a date from the calendar.
The problem is that I can't seem to find any actions in CodeCeption that allows you to click on something else than a an anchor or a button.
The doc clearly states : Perform a click on a link or a button, given by a locator.
public function click($link, $context = null)
There are also similar functions that do something similar, but not with the left mouse button
public function clickWithRightButton($cssOrXPath)
public function doubleClick($cssOrXPath)
This seems so trivial that I can't find anything about it. Why isn't there a clickWithLeftButton? Am I missing something here? I'm just starting with acceptance tests with CodeCeption.
I may not fully understand the question, but have you tried
$I->waitForText('Text User would click on Here', 30);
$I->click('Text User would click on Here');
I'm having difficulty trapping a programmatically triggered click event on a hidden button control from a ASP.NET MVC 4 web app inside a VB6 thick client (which is using a web browser control). I'm able to trap the click event itself using the following:
Private WithEvents WebDoc As HTMLDocument
Private Function WebDoc_onclick() As Boolean
Select Case WebDoc.activeElement.iD
Case "A"
Do something
Case "C"
Do something else
End Select
WebDoc_onclick = True
End Function
And this works just fine if the control is visible. But if the control is invisible:
<div class="HideBtnDiv">
<input id="C" name="NoItems" type="button" class="BtnDiv" style="display:none"/>
</div>
and I try to trigger a programmatic click via one of the following:
$("#C").('click');
$("#C").trigger('click');
$("#C").triggerhandler("click");
$("#C").focus();
$("#C").trigger('click');
I'm getting an empty string for the "id" attribute and as a result I can't distinguish which button was clicked. This button serves no purpose other than to indicate to the VB6 app that a certain criteria has been met and that's the reason why I need it to be hidden. Does anyone have any idea why the id is getting stripped? Or is there any other way to communicate back to the client?
I've also tried filtering by element style using
Select Case WebDoc.activeElement.Style
Case "display:none"
Do something else
End Select
but it came back as "[Object]" so no luck there either. Please let me know if there is a way around this.
Thanks,
Lijin
You seem to have tried several ways of dynamically triggering the click event, but did you try the most obvious way:
$("#C").click();
???
But here is what I would do:
1- Make all of your buttons visible, by removing "display:none" from their style
2- Wrap the buttons you want to hide in a new DIV
3- Set "display:none" style in the newly created DIV
4- You can then trigger the .click() event of any button even if not visible by calling $(id).click();
Thanks, Ahmad. Actually I meant .click() not .('click'). Sorry about that.
Anyway, I tried your suggestion and made the button visible and set the style of the wrapping div to display:none but the id attribute was still coming through as an empty string.
However, I did figure out another way to get this to work. If I keep the wrapping div and button as visible and then focus and click when the condition is met and then do a hide(), my problem is resolved!
$("#C").focus();
$("#C").trigger('click');
$("#C").hide();
The button doesn't get displayed and VB6 still passes the id on the click event. The weird thing is it requires the focus() call to still be made. Without it, I'm back to square one. Not sure if this is a bug.
I think I need to bind data programmatically to solve my problem.
I use a TabHost which hosts 2 Tabs.
I need to load the MvxBindableListView in the second tab when TabHost appears and keep the first tab as default tab.
What I'm doing is starting the second tab activity without problem because I check the process using this code:
protected override void OnViewModelSet()
{
SetContentView(Resource.Layout.Page_ActivityView);
System.Diagnostics.Debug.WriteLine("activityView started");
MvxBindableListView mvxBindableListView = FindViewById<MvxBindableListView>(Resource.Id.mvxBindableListView);
mvxBindableListView.ChildViewAdded += new System.EventHandler<Android.Views.ViewGroup.ChildViewAddedEventArgs>(mvxBindableListView_ChildViewAdded);
}
"activityView started" is displayed in output debugger, but MvxBindableListView.ChildViewAdded event isn't raised, only when I click the second tab.
So I suppose that MvxBindableListView is not databound.
Thanks in advance to help me loading my second tab programmatically.
I think ChildViewAdded is an event that occurs when the ListView is rendered - at that time when it needs to 'draw list items', then it will ask its adapter for child Views for the screen. As you scroll down the list, it will then ask for more child views - but it will also reuse views - so for a simple list you should only ever (hopefully) get N+1 calls on ChildViewAdded for a list which shows N items at one time.
So it's perfectly possible for a list to be databound but never to call ChildViewAdded - that won't get called until the list is 'drawn'
Sadly the Xamarin docs aren't helpful here - http://docs.mono-android.net/monodoc.ashx?link=E%3AAndroid.Views.ViewGroup.ChildViewAdded
Note: if you do actually want to bind programatically, then you can do this to - using Bind() methods and extension methods. However, I haven't expanded on that here - as it doesn't sound like that's actually what you need!
I've been working on Chrome Extension for a website for the past couple of days. It's coming along really nicely but I've encountered a problem that you might be able to help with.
Here's an outline of what the extension does (this functionality is complete):
A user can enter their username and password into the extensions popup - and verify their user account for the particular website
When a user browses http://twitter.com a content script is dynamically included that manipulates the DOM to include an extra button next to each tweet displayed.
When a user clicks this button they are presented with a dialog box
I've made a lot of progress but here is my problem:
When a user visits Twitter the content script is activated and all tweets on the page get my new button - but if the user then clicks 'More...' and dynamically loads the next 20 tweets... these new additions to the page DOM do not get affected by the content script (because it is already loaded).
I could add an event listener to the 'More...' button so it then triggers the original content script again (and adds the new button) but i would have to predict the length of twitter's ajax request response.
I can't tap into their Ajax request that pulls in more tweets and call my addCurateButton() function once the request is complete.
What do you think is the best solution? (if there is one)
What you want to do is to re-execute your content-script every time the DOM is changed. Luckily there is an event for that. Have a look at the mutation event called DOMNodeInserted.
Rewrite your content script so that it attaches an event listener to the body of the DOM for the DOMNodeInserted event. See the example below:
var isActive = false;
/* Your function that injects your buttons */
var inject = function() {
if (isActive) {
console.log('INFO: Injection already active');
return;
}
try {
isActive = true;
//inject your buttons here
//for the sake of the example I just put an alert here.
alert("Hello. The DOM just changed.");
} catch(e) {
console.error("ERROR: " + e.toString());
} finally {
isActive = false;
}
};
document.body.addEventListener("DOMNodeInserted", inject, false);
The last line will add the event listener. When a page loads the event is triggered quite often so you should define a boolean (e.g. var isActive), that you initialize to false. Whenever the inject function is run check whether isActive == true and then abort the injection to not execute it too often at the same time.
Interacting with Ajax is probably the hardest thing to coax a content script to do, but I think you’re on the right track. There are a couple different approaches I’ve taken to solving this problem. In your case, though, I think a combination of the two approaches (which I’ll explain last) would be best.
Attach event listeners to the DOM to detect relevant changes. This solution is what you’ve suggested and introduces the race condition.
Continuously inspect the DOM for changes from inside a loop (preferably one executed with setInterval). This solution would be effective, but relatively inefficient.
The best-of-both-worlds approach would be to initiate the inspection loop only after the more button is pressed. This solution would both avoid the timing issue and be efficient.
You can attach an event-handler on the button, or link that is used for fetching more results. Then attach a function to it such that whenever the button is clicked, your extension removes all the buttons from DOM and starts over inserting them, or check weather your button exists in that particular class of DOM element or not and attach a button if it doesn't.
