The document discusses automated agile testing and test-driven development approaches like behavior driven development (BDD) and acceptance test driven development (ATDD). It describes the BDD process, using the Given-When-Then format for writing acceptance criteria and test cases. Example tools for ATDD, BDD, and test-driven development are provided. Best practices mentioned include using BDD for collaboration, acceptance tests, and test-driven development for coding.

- 10. Acceptance Test Driven Development Acceptance Test-Driven Development (ATDD) is a development methodology based on communication between the business customers, the developers, and the testers. ATDD encompasses many of the same practices as Specification by Example, Behavior Driven Development (BDD), Example-Driven Development (EDD), and Story Test-Driven Development (SDD). All these processes aid developers and testers in understanding the customer’s needs prior to implementation and allow customers to be able to converse in their own domain language. © 2013 iZenBridge | CONFIDENTIAL

- 12. Advantage of ATDD © 2013 iZenBridge | CONFIDENTIAL Close collaboration Seeing concrete, working software Building trust and confidence Customer in control Evolving a shared language Tests as a shared language Tests as specification Specification by example
- 13. Behavior Driven Development (BDD) BDD is a second-generation, outside-in, pull-based, multiple-stakeholder, multiple-scale, high-automation, agile methodology. It describes a cycle of interactions with well-defined outputs, resulting in the delivery of working, tested software that matters. – Dan North © 2013 iZenBridge | CONFIDENTIAL
- 14. BDD is a Agile process BDD encourages collaboration between developers, QA and non-technical or business participants in a software project. © 2013 iZenBridge | CONFIDENTIAL

- 16. © 2013 iZenBridge | CONFIDENTIAL BDD Story: Returns go to stock In order to keep track of stock As a store owner I want to add items back to stock when they're returned Scenario 1: Refunded items should be returned to stock Given a customer previously bought a black sweater from me And I currently have three black sweaters left in stock When he returns the sweater for a refund Then I should have four black sweaters in stock
- 17. © 2013 iZenBridge | CONFIDENTIAL BDD Scenario 2: Replaced items should be returned to stock Given that a customer buys a blue garment And I have two blue garments in stock And three black garments in stock. When he returns the garment for a replacement in black, Then I should have three blue garments in stock And two black garments in stock

- 20. BDD in Action © 2013 iZenBridge | CONFIDENTIAL Story As a account I want to add two numbers so that I get sum of the two numbers immediately without having to do manually. Acceptance Criteria 1. It should only allow the integer numbers in the two fields 2. The two numbers should be less than 1000 3. The two numbers should not be less than 0 4. The sum of the two numbers should be shown in the ‘Result’ field
- 21. Best Practices • Use BDD to collaborate • You may use it for Acceptance Test • Use TDD for coding • Refactor regularly • Refactor to Design Patterns • Focus on continuous Delivery © 2013 iZenBridge | CONFIDENTIAL
