I know you have comment steps, and I can do this in the Code behind, but what if there are no coded steps?  I would like a way to have a place to describe my test and give the ability to include TODOs, limitations, etc.

The project is initially created in the standalone Test Studio IDE and is connected to a remote Git repository. Then it is exported to Visual Studio and when trying to run test lists in the VS Test Explorer, they don't start at all. 

The Tests output contains an error when trying to run a test list: 

Error preparing project for command line run: Could not create an instance of type ArtOfTest.Common.SourceControl.IRepositoryInfo. 

The workaround is to clear the Source Control Binding from the Test Studio Standalone IDE with the options Discconect from Source Control and then Remove Source Control Binding. See these options in the screenshot from this link.

Hi there,


I'm looking for some clarification on what settings can be changed when passing a settings file to the ArtOfTestRunner.exe.

When I try to run a test list the settings for "Web" appear to follow the values I set as well as being able to change the Execution Delay, however when I try to change the 'RerunFailedTests' value it will still use the value set in the original list. 


Example settings.json I used

{	"Settings": {
  "__type": "ArtOfTest.WebAii.Core.Settings", "__value": {
    "Web": {  "__type": "ArtOfTest.WebAii.Core.Settings+WebSettings", "__value": {
        "RecycleBrowser": false,
        "DefaultBrowser": 12,
        "BaseUrl": "",
        "KillBrowserProcessOnClose": false,
        "KillBrowsersBeforeStart": false
    "ExecutionDelay": 0,
    "RerunFailedTests": true

How can I pass in the  RerunFailedTests value from the settings json file?


Thanks for your help,

Executing a test with double click action on Windows 10 machine with Chrome browser, enabled for automation with extension, is failing on the double click action when executed in code. 

Test Studio version 2022.3.xx. 

Sample test shared internally.

Visual Studio 17.4.3 crashes when your rebuild a Test Studio project.

To reproduce the issue you need to create new project with only one test and a few steps. Then, build the project and Visual Studio becomes not responding.

Steps to reproduce: 

  1. In a test add an element through the highlighting menu -> Add Element to Repository.
  2. Create a step through the Step Builder for that element.
  3. Convert the step to code. Note: The test should not use any other recorded element in code. 
  4. At this point the element is only referenced in the test as Independent.
  5. Locally it is executed with no errors. 

Expected: To be executed with no errors on a remote machine. 
Actual: When executed through the Scheduling it results in compilation errors similar to this: 

 error CS1061: 'ProjectNamespace.Pages' does not contain a definition for 'PageNodeFriendlyName' and no extension method 'PageNodeFriendlyName' accepting a first argument of type 'ProjectNamespace.Pages' could be found (are you missing a using directive or an assembly reference?)

I am not able to add Test Explorer Settings to my project in Visual Studio. I am missing the assembly LoadTestPackage and I was notified that this feature has been deprecated in VS 2022.

The support team at Test Studio mentioned an alternative solution with the Run Settings as possible solution, but it is not yet implemented.

By design the Wait for exist step doesn't record an image for the element. However, you can manually add an image for the element in that step. And if this is the case the fallback to image search (when the find expression doesn't match an element on the page) remains only in the background - there is no message that the element is found by image only in the execution log. 

Steps to reproduce:

1. Use a wait for exist step with an image for the element.
2. Ensure the element find logic will fail to locate the element.
3. Ensure the image will match an image on the page. 
4. Run the test. 

Expected: The element to be located by image as a fallback search criteria and get the message and warning in the execution log for that. 

Actual: The test passes, but never informs that the element was found by image only.

 At Execute for all tests I'm getting this error:

20:44:39 'INFO' > Build Failed

I spent an hour analyzing it. The only thing I can see in the code is the fact that, for each file with the error there is code from a file I no longer use. Here is the suspect:


  <CodedStep("Verify 'TextContent' 'Exact' 'Home' on 'HomeDiv'")> _
        Public Sub LogOnBase_CodedStep()
                        Pages.HttpsPedcoreui.HomeDiv.AssertContent().TextContent(ArtOfTest.Common.StringCompareType.Exact, "Home")

        End Sub

I'd really like to talk to someone as there are other HomeDivs in the files so I don't want to start deleting steps.

Dear Telerik team,

I would like to verify if an image has appeared at a certain position in my desktop application. I found in the Telerik documentation that this is possible for Web and WPF tests. Is this feature also available for desktop tests? Or is there some trick to verify the image without this feature?

I am currently using the free trial version of Telerik Test Studio to see if it meets all my needs and whether I will get the full version.


Thank you

Steps to reproduce: 

  1. Set the dark theme in Test Studio.
  2. Go to the Reports tab and choose some test runs to create a report.
  3. Export this to an image or html.

Expected: The x-axis and y-axis of the bar chart to be listed in the exported image. The colour legend next to the pie chart to be specified. 

Actual: These are missing. 

Note: If the export is performed from the light theme, the mentioned legend is output as expected.

I have a request that uses GET protocol and as well as it uses some body. I modified to POST or other protocols. This time error differs. I looked it up it is possible to send body through Get call, although not recommended for sure. However, I need the test studio to be able to do this.

  1. Local scheduling setup - default installation of Test Studio with no services added.
  2. Project is connected locally.
  3. Schedule a test list (recurring or for some time ahead).
  4. Make a change in a test from the test list. 
  5. Save the changes - the automatic upload prompt appears on each save action. 
  6. If you choose to not show it again, the automatic upload gets triggered without showing that notification.
  7. As a result it produces error message saying "Scheduling service at http://localhost:8009 is reporting that it cannot communicate with Storage Service at http://<theMachineName>:8492/v1". 

Expected is that there shouldn't be any calls to the Storage Service.
Actual is that the attempt for upload to the Storage is triggered for local setup as well.

Visual Studio 2019 crashes after opening and closing tests and working on them for some time. The memory that Visual Studio uses increases to the point where it slows down and eventually crashes. 

There are errors from VSTSExecution in the Windows Event Viewer log and other errors about faulting module "C:\WINDOWS\System32\KERNELBASE.dll" from the time of the crash.

Sample date picker used here

Steps to reproduce:

  1. Start recording session and try to enter date into the date input

Expected: To record a step to 'Enter Text'
Actual: A 'Click' step gets recorded and no date entered is registered in the test. 


  1. Navigate to the page where is the date picker - I used this sample
  2. Add the date input field into the test elements (the Elements Explorer) - for this you can either use the recorded click step, or highlight the element and choose to add it to the element repository. 
  3. Once the element is into the project, you can add steps for it from the Step Builder - that includes the 'Enter text' action as well (from the Quick Actions section). 
  4. Type the date you want to enter without using the slashes - for example 1072022 for today's date. 
  5. Execute this step - you can use the partial test run options to execute only that step. Check what happens upon execution.
    Note: The Enter text step consists of few actions one after the other - these include a click action, which is being sent by default in the absolute center of the input field. Depending on the date picker implementation that could bring some inconsistency when entering the date - for example the month doesn't get changed at all. Actually if you manually click in the center of the input (even if this is not that precise) and enter the date, you will see the same behavior. If you click over the month, though, in the left part of the input you can then enter the date correctly. 
    If this is the case, you will need the adjustments described in the next steps. These will actually change the click action so that it clicks on the left side of the input.
  6. The 'Enter text' step needs to be converted to code in order to modify the properties of the click action. When the step is edited in code you can see the MouseClick() method is the default one and doesn't use any parameters. You can directly choose any of the methods overloads and specify a click point in the input field. 
  7. If you are not proficient in code writing and need some assistance to identify the right method to specify the location, you can use the following approach - while recording add a mouse click step through the Advanced Recording tools and choose the option to click on specific point from the target element. 
  8. Once you have that step, you can convert it to code - that way you can see the MouseClick() method and what attributes it uses to click on a specific point. You can copy that line of code and replace the click action in the 'Enter text' step sequence. 
  9. Then, remove or uncheck from the test the help mouse click step used to sort out the code.
