This talk is about a ruby gem I wrote for adding visual assertion with selenium as driver.

While we continuously implement new functionalities in our app, automated functional tests acts as safety net and gives us confidence. Still, there is something missing. Many times we get feedback like:
"Sign-In button has shifted and user have to scroll down to see it"
"We wanted to change background color of screen-X, it got changed for Screen-Y screen as well"
"Why has fonts of this link become so tiny?”
I am working on customer facing enterprise level Mobile apps of one of the biggest airline in the world. For us user experience is as important as functionality.
Our regression suit did not have capability to catch such issues. Moreover, we started building another airline app from the same codebase with only change in user interface of this new app. This means, change done for one app, affects another. Hence, it became really critical to enhance our automation with visual assertions.
To accomplish this, I worte my own gem called 'nakal'.http://rubygems.org/gems/nakal

This is going to be a Talk + Demonstration

While we continuously implement new functionalities in our mobile app, automated functional tests acts as safety net and gives us confidance. Still, there is something missing. Many times we get feedbacks from clients like:
"Sign-In button has shifted a bit and user have to scroll down to see it"
"We asked to change background color of screen-X, it got changed for Screen-Y screen as well"
"Why has fonts of this link become so tiny?”

There are many tools which can do this, but they charge hefty money and also does not give full flexibility. Therefore, I worte my own gem called 'nakal'.http://rubygems.org/gems/nakal
