The best thing I like about this software is its flexibility. I can create any kind of environment regardless of the complexity. The software does not always work as intended hence I have had to use my own logic to make it work. It has never given me a problem that could not be solved by using my own logic. This program makes creating test environments easy and gives me complete control over the process. The most helpful tool is that users can use this software without any technical knowledge. It is also very easy to customize the software as per our needs. It has great support service and easy to integrate in other applications. I haven't found anything which I dislike about this software. This is one of the best tools for testing. We are using it for mobile application testing. It helps us to test various devices like mobiles, tablets etc.
