Hi Team,

Our test application use java script navigator.clipboard.writetext  to copy content into clipboard, when we run cases with telerik 2024, some scenario pops error "fail to copy", the exception for java script is "NotAllowedError: Failed to execute 'writeText' on 'Clipboard': Write permission denied.".

After check, we can see it's because clipboard-write is denied when telerik open browser, but if we manually open the browser, it's fine. Only failed for browser which is opened by telerik.

You can use below example code to check in browsers which is opened by telerik.

test code:

// Initialize the settings

mySettings = new Settings();

// Set the default browser

mySettings.Web.DefaultBrowser = BrowserType.Chrome;  // we can change the two lines for different scenario test

mySettings.Web.UseBrowserExtension = false;

myManager = new Manager(mySettings);

// Start the manager

myManager.Start();

// Launch a new browser instance. [This will launch an IE instance given the setting above]

myManager.LaunchNewBrowser();

myManager.ActiveBrowser.NavigateTo("https://www.telerik.com");

await navigator.permissions.query({

        name: 'clipboard-write',

    });

Below is what I have summary for telerik 2024 and 2022, please help to confirm if all the the denied scenarios are expected.

Thanks,

Hi,

I've created a simple test for a WPF application that clicks a button in my main window to open another window and then clicks a button in this window. Half of the time the test executes as expected, half of the time it fails, because the window was not found. I added a delay before clicking the second button to make sure, that the window is fully loaded. The title of the window is always the same.

I've tried to create a test like this for another window, but there I have the same issue.

Why is the Test Studio not able to find the window and is there anything I can do to fix this? 

 

This are the logs:

Hi Team, 

After we upgrade telerik 2024(we have tried Q1, QA2, QA3), we found some of our cases with keyboard operation do not work now, below is the list, could you please help to check, no exception, just not work actually. Not all, just some. And the old version Testing_Framework_2022_1_0601_1_Free could work well.

Publish shortcut key

F5 --- Refresh the page

Control + R  --- Refresh the page

Control + Tab  --- switch tab

Control + Shift + Tab --- switch tab

Alt + Left ---- go back 

Alt + Right  --- go forward

Shift + End  ---- select to the end

Control + multiple select ---- select multiple

Shift + select two range ---- select range

Private application keyboard

Control + Alt + L   ---open the navigation panel

Control + Shift + OemQuestion   ---- Open the help dialog

Control + Shift + H   ---- open home page

 

Thanks,

Hi Team, 

We met one issue, for click copy button and get clip text, with telerik 2024, chrome could work well, but chrome headless couldn't work well, the text is always empty.

The code we use is like this::

Clipboard.Clear();

copybutton.click();

Clipboard.GetText();

Can you give some suggestion about this?'

 

Thanks very much,

Jun

Hi Team,

We are reviewing test results for chromeheadless, we found below exception for some cases run together, which can be reproduced. But they are good for chrome, seems only chromeheadless issue.

The exception is like below, I couldn't find any clue for it, can you give me any suggestion about why such exception occur, so that we can try to fix it.

Hi Team,

I am trying chromeheadless now, most of the UI operations could work, but for keybord, which do not work, like below:

Manager.Current.Desktop.KeyBoard.KeyDown(Keys.Alt);
Manager.Current.Desktop.KeyBoard.KeyPress(Keys.End);
Manager.Current.Desktop.KeyBoard.KeyUp(Keys.Alt);

 

It's not always broken, when I use it in my case, the same code work for chrome, but broken for chromeheadless, i don't know how to debug the issue. Can you please help to check for us?

I use ActiveBrowser.Cookies.GetCookies(BaseUri); to get browser cookie, cookie is got, but all expired cookie. The same code if I set chrome not headless, which could get un-expired cookie. Is it not supported yet?

Chrome headless：

Hi Jun,

Thanks,

Jun

I searched lot, seems old version not support, not sure if the latest version support, but after I try not good. We also tried use keyboard to switch tab, which could switch successfully, but active browser will not switch.

Hello,

I am currently evaluating Telerik Test Studio Dev Edition (Visual Studio Plugin) with a trial license.
I successfully created a few WPF Tests in a sample application I created from scratch using .NET 6, WPF and some Telerik UI for WPF components (e.g. RadGridView). Here, the recording works perfectly. When I click on Start by recording Test Steps, the application starts, gets unresponsive for ashort while (~3 sec.) and then the Recorder overlay appears and I can record the test.

But then I tried to automate tests for a small tool, let's call it SmallTool, which is also a .NET 6 WPF application. But here, recording only works by using a Desktop Test. This limits the available test steps significantly (e.g. I cannot "evaluate the third item in this List"), so the tests become useless.

Here are the differences between my sample project and SmallTool that I notice:

• SmallTool does not use any Telerik UI lib
• SmallTool does use two COM references (for interaction with outlook)

I also already checked the Desktop Application Will Not Record support article. My SmallTool did appear as a WPF application.

Can you help me with getting WPF tests to work?
