In this presentation, Pravinkumar of Valuebound has talked about Behavior Driven Development (BDD) - a software development methodology in which an application is designed by describing how its behavior should appear to an outside observer. This methodology is great for increasing developers and clients satisfaction. Here he has also discussed on various agendas, like automated tests using Behat, Gherckin Structure and finally, a demo. ---------------------------------------------------------- Get Socialistic Our website: http://valuebound.com/ LinkedIn: http://bit.ly/2eKgdux Facebook: https://www.facebook.com/valuebound/

4. Behavior Driven Development
It is a methodology to support you in

14. Given
Defines the initial state of the system for the scenario
When
Describes the action taken by the person/role
Then
Describes the observable system state after the action has
been performed
And/But
Can be added to create multiple Given/When/Then lines

Lines starts with Feature keyword followed by three indentended lines.
Contains list of scenarios
Tags are used to group features and scenarios together

16. A php framework for
autotesting your business
expectations.

17. .. is a BDD (behavior driven
development) framework for PHP.

Behat is a library
easily installed
using composer

19. 1. Run the command

Behat setup step 1

20. Behat setup step 2
1. Create a config file called “behat.yml” file.
2. Let, will tell to behat which instance we want to test features.
3. Create a Feature, scenario, steps and run the script….
