I am a tester. We use one tool which contains pages developed using Flash. I need to automate few tasks which are repetitive for our testing purpose. I have knowledge on Seleniu
I have solved this by using Neoload. Then I could record my browsing flow (even though this is a webpage base on flash) web page browsing. https://www.neotys.com/blog/
I did not like the experience working with this tool but it solved my problem. To bad it is licence product. This might be a problem if you plan to use this in a CI/CD system with a low budget.
