5. How the customer explained it...

6. How the project leader understood it...

7. How the programmers wrote it...

10. example-based communication
Business
and
developers
can clearly
understand

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

15. Feature
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 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….
