BDD – Collaboration & Hands-on practicesKostas Mamalis

“The most important problem that we face as software professionals is this: If somebody

thinks of a good idea, how do we deliver it to users as quickly as possible?”

- “Continuous Delivery” book

➜ Ubiquitous Language➜ Focus on business value➜ Living Documentation➜ Specifying By Example

How does BDD come to the picture?

➜ Because we have to deliver ‘software that matters’ – Agile Manifesto

Why do we need to focus on software behaviour

“Here’s the water you’ve asked for, sir!”

The Power of the 3 voices

The Voice of the Solution

The Voice of Quality

The Client’s Voice

It’s all about:…

And Scenarios of course!

Who writes the Scenarios and When?

A few tips & ideas

Definition of Ready & Definition of Done- Definition of Ready- Definition of Done- 2 parallel boards

Acceptance Criteria & Example Mapping- Acceptance Criteria – how are they related to

Scenarios?- Example Mapping- How about Non Functional Requirements/Criteria?- Automation is not always the outcome of a

Specification session- Team Rotation?

Roles

- Do we need Developers in Test?- We are all developers - Testers you are still needed!!!

• What happens when business are not as involved into your processes?

• Product Owner/Business Analysts are a catalyst to the BDD process

• Unit & Integration Tests, then Acceptance

Business Involvement + Test-First Maturity

Test Pyramid (no Ice-Cream cones please!)

- BDD describes behaviour- BDD doesn’t need UI- BDD doesn’t restrict on one layer of

your system- You can do BDD with xUnit

frameworks- Unit + Service tests with Test Doubles- Drive majority of tests from API- How about SPAs?

I’m a full-stack developer, can I do BDD?

“Given, Given, And, Then, When, Then…”

How about Fluent APIs then?

What if Gherkin language gets in the way?
