Using the ClosesBrowser Property for Pop-ups

Pop-ups can have a control (usually a button) which invokes an event that closes the pop-up. This can cause problems when performing UI Automation with Test Studio.


"Click"-type of steps have a property called "ClosesBrowser":

ClosesBrowser property

Depending on the implementation of the pop-up, Test Studio may or may not detect the cases where this property needs to be set to Ttrue. Symptoms related to this issue can be:

  • Click steps timing out after the actual click occurred during execution.

  • Click steps failing with a seemingly random exception message:

    ExecuteCommand failed: BrowserCommand (Type:'Information', Info:'IsReady', Action:'NotSet', Tergaet:'null', Data:'', ClientID:'Client_034ab38c-2736-49b3-9b45-986d2990bc07', HasFrames:'False', frameInfo:'', TargetFrameIndex:'-1', InError:'False', Response:'') InnerException: System.IO.IOException: *Pipe is broken*. at System.IO.Pipes.PipeStream.WinIOError(Int32 errorCode) at System.IO.Pipes.PipeStream.WaitForpipeDrain()

  • If the click step is followed by a "Close pop-up window" step, this likely indicates the button invokes a Closing event. However, this problem can occur even if your test contains no "Connect to pop-up window" or "Close pop-up window" steps. This is because some pop-ups are implemented in a non-standard way. In these cases, set ClosesBrowser to True. Select the "Click" step, then change this setting from the Property menu on the right.

  • Setting the Click step's SimulateRealClick property to True resolves the issue.
