Program Overview: Two Day Training and Coaching – Hands-on workshop
Acceptance tests prove your solution actually works, and using them to implement executable specifications proves your solution does what it should do. In this course we look at capturing requirements as executable specifications and implementing them as end-to-end tests with Behat.
Format of Workshop:
Participants get to understand behavior driven development in the form of sessions and hands-on exercises and discussions.
Learning Outcomes:
Behat is an absolute favorite library to use. First, it let’s you think about the behavior of the features first, before you start developing. In this tutorial, we’ll do that, and it’ll change the way you develop. Second, Behat turns that written behavior into functional tests against your application. Does your feature behave correctly? Just run the automated robots to find out!
Along the way, we’ll master Mink – the partner library to Behat. Here are the learning outcomes of this workshop:
- That BDD is primarily a communication tool, to be used by the whole team
- Understand other disciplines, perspectives on communication issues within the team
- Understand the importance of developing a ubiquitous language within the team
- Experience of the BDD process: breaking down user stories into scenarios
- Understand the distinction between features, user stories. acceptance criteria and scenarios, and how those artifacts can be used by each discipline
- Understand the difference between unit testing and acceptance testing, and the
importance of each - See what Behat is, and how it can be used to automate BDD scenarios
- Learn the syntax of Behat and implement the same for acceptance scenarios
Following topics in detail will be addressed in 2 days:
- What is BDD?
- Practical exercise: breaking down user stories into scenarios
- Writing acceptance criteria for user stories
- Feature acceptance tests

When conducting these workshops, we focus on an organization’s specific needs, challenges and expertise level in Agile as BDD implementation has lot to do with Agile maturity of a team/organization.
Facilitator will address all the questions from participants about applying BDD practices on real life projects.
