Unexpected Exception thrown while test running in TestStudio

[fabrice]

I am testing in Firefox 51 , using TestStudio  build 2016.3.1304

 

Sometimes the  runner would simply fail for no apparent reason and throw out the following error:

--------------------------------------------------------------

 

Unexpected error while waiting on condition. Error: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> ArtOfTest.WebAii.Exceptions.ExecuteCommandException: ExecuteCommand failed!

Hello Fabrice,

Thank you for choosing Telerik Test Studio.

The issue you are facing is due to the changes introduced with the latest Firefox edition. We have tested it and applied some fixes which will be introduced in our future official release which is planned for the upcoming week. Once the release is published I would recommend you upgrade to it and then give a try to the Firefox automation you have and in case you face any of the reported difficulties contact us again.

I hope this sounds reasonable enough to you. Thanks in advance for your understanding!

Thanks Elena,  the issue can also be seen in the latest version of Chrome 56.0.29.

Is the new build expected to be released this week ?

Hello Fabrice,

The official 2017 R1 release is now live and you could update your Test Studio. 

Please give a try to the latest version and let me know if you continue facing the same behavior. If you encounter the same error please provide us further details on it. 
- Does always the same test fail? 
- Does it fail on the same step? 
- Is there anything specific for that test/step? 

I will appreciate whatever might be of further help for an occasional investigation. Thanks a lot in advance!
