Geb:
Geb is a testing framework for automation of browser which is written on top of Selenium WebDriver library so it can works on all browsers that is supported by Selenium. We have two added benefit in one way we are working with Geb that provides an extra layer of convenience and productivity but we have freedom to switch back to Selenium to perform all the automation in Selenium Ways.

Geb uses the dynamic language features of Groovy to provide a powerful content definition DSL (for modelling content for reuse) and key concepts from jQuery to provide a powerful content inspection and traveral API (for finding and interacting with content). So in another word we could say 

GEB = Selenium WebDriver + Java +Groovy +Jquery

Spock:
In this course we would be learning one more testing framework Spock that is again a very sophisticated testing and specification based framework for Java and Groovy. Spock Testing framework uses a very expressive and to the point specification language. 

Please watch this course at 1.25X or 1.5X speed to avoid long wait in speech.

This course is going to give you confidence in web application automation with Geb and Spock.
So wish you all a happy learning and hope for the birth of one more Automation Engineer.

Note:  I would be happy to help you through answering your GEB and SPOCK related query in Q&A section. So don't hesitate to ask your query in Q&A section of this course
