The browse button, which allows you to set the path to the WebDriver is not showing. It is hidden by the vertical scroll bar in the Project Settings -> Browsers tab (see hiddenButton.png).
As a workaround, you can set the WebDriver path from Test Studio's Test Runner (see workaroundTestRunner.png).
CaptureBrowser() functionality does not work as expected with Firefox browser on Windows 10 version 2004. The captured image shows only the browser frame and and white contend of the browser.
The load test fails to upload to the database, if there is a "." in any of the header names. The limitation comes from MongoDB's driver.
As a workaround, you can change the header name to not include "." or delete the key-value pair from the .tstest file.
The HTML output from ArtOfTest.Runner.exe from failed test is missing the expected and actual image on failure. The same details are available, if the output is generated from Test Studio Standalone version.
The actual image on failure exists in the specified output location, but is not included in the HTML. When you open the results with the Result Viewer, you can see the actual image on failure, but the expected image is still missing. Maybe those are 2 separate things to look at.
Both options to delete a cookie by domain and by cookie do not work for Chrome and Firefox. It still works for Internet Explorer though.
The ClearBrowserCache step is working as expected and clears all cookies.
