The stability of the solution is good. We haven't had any issues, and even if we're stuck, the solution's team will support us and help us overcome any issues we're having in relation to stability. For us, stability is not a problem.

It was stable. It didn't crash and ran as expected.

I have been using Silk Test since version 15. When I used it, it was a really good solution but there is still a lot that can be improved.

The solution is stable. 

No issues encountered.

At the moment, when we are trying to use this tool, we are finding quite a few compatibility issues between the tool and the applications on the test. We wouldn't consider it perfectly stable for that reason.

Sometimes it was hard to handle long runs which take longer than 12 hours. Agent or IDE could hang from time to time. But in overall, SilkTest was pretty stable even on machines which were working weeks without any restart

If you use it inside Visual Studio, it is very stable. If it's not in Visual Studio, there are a lot of components to test. There are about ten different ways for it to be used. It's quite stable. 

In my opinion the program is very stable.

None that I can think of. I had some issues related to Chrome, but that's something I had also encountered previously, in the Selenium world.

No issues with deployment.

Less issues with the Classic agent, but with the Open one we have faced some issue.

No issues encountered.

We've had no issues with stability.
