When recording a custom web application in Chrome, Firefox or Edge, no steps are added after the navigate step. There are elements listed in the DOM tree, but no steps can be added for these from the Advanced Recording tools. Highlighting is also not working. 

If recording the actions in IE these are captured and listed in the test. This recorded test can be executed against the other browsers.

Extracted text from one element (PPSR FSID), used binding to set in another element (PPSR Search using FSID), Test failed because FSID could not be found, on closer inspection the set text had 2 different characters than the extracted text S instead of 8 and T instead of 7 (sorry snip is so wide) Have attached zipped code.

During a recording session with enabled Hover Over Highlighting, the context menu with recording options disappears before we can use it. This make it hard to add verification and action steps or locate the element in the DOM tree.

This only happens in one of the ComboBox dropdown controls.

Specific result file with web tests results cannot be exported to HTML format. If uploaded to the storage database, it is loaded in the Executive dashboard. But when trying to drill down the test results, there is a message that load test results are not supported.

Chrome Headless Failed to Select ByText when text value includes apostrophe.

The workaround is to select ByIndex or ByValue, if the value does not have an apostrophe.

Test Studio scheduled runs sometimes start browser in the background and it loses focus. Due to that the test steps are not executed correctly and the test fails unexpectedly.

This does not happen when running the test or test list locally.

The tests and test lists are visible in the Test Explorer and can be run the first time you open the Test Studio project in Visual Studio 2019. After any changes or rebuilding the solution, the tests and test lists disappear from the Test Explorer.

The issue is related to the latest version of Visual Studio 2019 and is recognized in build 16.10.2.

We have a large PDF (60+ pages) and try to verify certain content on specific pages. During the recording process some elements are captured with TagName and TextContent and others with TagIndex. In this scenario TagIndex is not reliably, because the document is large and the elements change dynamicaly.

One solution is to update the element's find logic manually on all elements that use TagIndex, but this is very time consuming. 

Another option is to use coded step to find the target element by TextContent and verify it.

We are unable to use TestStudio for WPF, when closing the window during recording we get an excpetion.

I tried and created simple wpf app in VS 2019 and get same results.

I attached a C# project as solution was to big.



Simple app is based on VS 2019 telerik for WPF project, created as blank.

Only code changed is adding a DispatcherUnhandledException on App class.


private void OnDispatcherUnhandledException(object sender, DispatcherUnhandledExceptionEventArgs e)
            if (e.Handled || e.Exception == null)
            e.Handled = true;



1) Create new project

2) Create new test for WPF 

3) Configure to the WPF app exe file

4) Click record

5) After test studio is connected close the window.


Expected results:

Window get closed without any problems.


Actual results:

While closing the window exception is being thrown that we.

Navigate to the application under test and click a link that opens in a new tab. Then, click within the new tab to redirect it to a new URL and close the tab. 

The result is that the Close pop-up window step is successful, but the tab is not closed. This results in issues with the following steps in the test scenario.

Nested data driven tests generates quite large results, even when there is no data in the bound data table (built-in or external). The result is almost twice the size of the same tests, if these are not using the data tables. The tests may be using InheritParentDataSource, but the behavior is similar if these are not using it as well. 

For real user scenarios, the large results may exceed the limitation of the file size (16MB), which can be transferred through the storage service. 

Investigate if it is possible to optimize the data driven test results, at least for the case, when the data source is empty.

The TextFromImage verification step extracts the wrong text in some scenarios.

One example is that the number "8" can be recognized as "3", when it is at the beginning of the element (text). Other times, the word "learn" is not extracted correctly from a sentence.

When you edit the "Wait for ExistsNot" step as coded step, the generated code does not reference the target element from the Pages. Instead, it creates a fixed find logic from the current state of the element in the Elements Explorer.

The issue is that when the find expression for that target element changes, the coded step fill not be updated.

Currently we have an Angular select control and we are experiencing troubles with the automation. The value is visibly selected but it is not used further in the application. It appears that the "OnInput" event is not triggered during the selection.

We have found a workaround, which is to trigger that event in a coded step:

// This is necessary to trigger event listener
