I am the only QA with 9 developers dealing with about 60 applications using different technologies. 

Now I needed to automate our apps. I have written some selenium scripts already but I stopped and contemplate about which kind of Framework I should be using before I would go further in my script creation? 

I am looking to `SpecFlow` to use for **BDD**. As I was looking into it, this would be very beneficial with BA to developers to stakeholders and manual QA. Since I only have this small team, is it advisable to go on with **BDD**?
I have heard of test driven development but I am not really sure how our automation framework would be called.
