When using Test Studio for API standalone, the coded step is deleted after reopening API project.

Steps to reproduce:

1. Open Test Studio for API standalone and add a coded step (C#)

2. Save project then close it

3. Reopen the project in Test Studio for API standalone and the coded step is no longer there and the Test Case will now show a VB# instead of C#

4. Recreate the coded step and the method will show "A class with this name is not found in the test's code-behind file"  

6. Click on open Code-Behind and the project will crash.

Note:  API Test as Step in Test Studio works as expected and reopening the API project within Test Studio doesn't delete the coded step.  However, we create a “common API project” that is shared with the QA team then imported into new test studio project.  We have a workaround but not ideal which is to create the API project within Test Studio and copy the API test folder to share with the QA team.

Steps to reproduce: 

1. Record a test against the demo page
2. Select an item from the DropDownList control.
3. Note! the recorded step to select an item from the dropdown is not the KendoAngularList one, but is the KendoListBox. 
4. Execute the test.
Expected: to pass the test.
Actual: the correct item from dropdown is selected, but the step is failing with unexpected error. 

Workaround to resolve the issue: Open Project Settings and disable the Kendo UI jQuery translators (or the ListBox one only), save the changes and re-record the respective steps in a new recording session. This will record the correct steps and the execution should work as expected.

When you are in recording mode (with the Recorder attached to the browser) and execute a Test as Step with Run -> From Here or Selected option, the dialogs in that test are not handled. 

The dialogs are handled, if you open the test from the Test as Step and use the same options Run -> From Here or Selected for the test itself.

I created a Drag & Drop step from the Step Builder during test recording and picked a specific target element for the Drop location. The steps is created and executed correctly, but I am not able to copy or delete it.

I can disable it, so it does not execute, but it remains in the tests as a step.

I have a project configured to Run Locally and a scheduled test list for execution in the future. The error message appears also if you have scheduled a recurring test list.

When I make a change in any of the tests, that are part of the test list, I get the message "Storage service unreachable". My setup does not have an use a Storage service and the test is actually updated and executed as expected.

Please fix the cases when this message appears unnecessarily.

If a data column name contains brackets and is something like: 'text (something) test' and you bind a step to it, upon execution the test fails to get column:

Column name 'text (something' does not exist!
System.ArgumentException: Column name 'text (something' does not exist!

The Check for JS errors step is not working on remote execution with the Test Studio Test Runner. I have no issues when executing locally on the machine with Test Studio.

This is causing troubles for the CI builds and scheduled execution.

Custom WPF application with specific control - ViewBox, causes the highlighting to be misaligned. 

In case the ViewBox control is removed from the application structure, the highlighting works as expected.

1. Create local data for a test.

2. Data bind the same test to external data source.

3. Remove the data binding to the external source.

At this point I can't use the local data for data driven test steps or find expressions.


The workaround is to right click on the test and go to Properties. Then enable both DataEnabled and DefaultToGrid.

Chrome v.77 cannot recognize OnBeforeUnload dialo. The dialog is not being recorded and if added manually (add Handle Confirm dialog step) from the Step Builder, the dialog is not handled during test execution.

A popup with "End of Central Directory record could not be found." error shows up when I try to add a custom step from the step builder.

When I restart Test Studio, the test works fine.

When I generate a unit test in Visual Studio 2019 from existing .tstest, the structure is incorrect. As a result the project has compilation errors.

Wait for exists step is failing with the error below, when Test Studio is not able to find the element:

Object reference not set to an instance of an object.
System.NullReferenceException: Object reference not set to an instance of an object.

As a result the conditional steps are not working as expected and the test fails.

The workaround for this issue is to change the WaitForExists step to VerifyExists step and the test works.

After installing my DevCraft package, my keyboard has limited functionality, when trying to create a new project/solution in Visual Studio 2019. I am able to use "space" and "backspace" keys, but not letters and numbers.

Uninstalled Test Studio Dev or disabling Telerik.TestStudio extension and I have full keyboard functionality on screen for creating a new project in Visual Studio 2019.

As a workaround I am able to use CTRL + V to paste any text from my clipboard.

Steps to reproduce: 

1. Open an Enter password step and expand in the step pane

2. Set the encrypt property

Expected: All fields with the actual text entered should be masked with *

Actual: If the step is expanded the actual text entered field does not change its value. 

Note: Reopening the test fixes the visual glitch.
