This talk was inspired by…


What is BDD?


[HttpPost]public ActionResult Answer(int answer){

TriviaEntities db = new TriviaEntities();var question = db.FindQuestion(CurrentQuestion);

if (question.Type == QuestionType.Easy){

db.AddScore(question, user, 10);}else{

db.AddScore(question, user, 50);}

var model = new GameModel{ Score = db.GetScore(question, user) };

return View(model);}

Classic model


Scenario: Correct easy answer scores 10

Given I register a team

When I submit a correct easy answer

Then my score should be 10

If you have these questions you are probably on the wrong track…


The Sprint Planning


Demo: Planning the Pizza Selection Story


Explain the story as a PO


Let’s write a Gherkin from the result

Scenario: ...

Given ...

When ...

Then ...


De-briefing

• PO was unprepared

• We discussed the topics in a foreign language

• The domain was known, but not very exact

• Quality of notes?

• How easy it to write the first scenario?

• Quality of scenario?


An efficient collaboration…


Demo: Planning the Pizza Selection Story


Participate in the facilitated discussion as PO


Review

• What was different from the first time?

• Did we cover more or less functionality than the last time?

• What do you think the different coloured cards / stickies are supposed to represent?

• How did capturing each of those help to keep the discussions on track?

• Do you think the story is ready to implement now? Why?


Should be able to add a pizza to the basket

Scenario: Should be able to add a pizza to the basket

Given the following pizza menu

| name | ingredients |

| Aslak Hellesøy | Cucumber, Gherkin, Pickles |

| Uncle Bob | Chicken, Low cal cheese |

| Chris Matts | Garlic, Wasabi, Tomato |

And the shopping basket is empty

When I choose a “Chris Matts” pizza

Then my basket contains 1 “Chris Matts” pizza


Should be able to add extras to the chosen pizza

Scenario: Should be able to add extras to the chosen pizza

Given the following pizzas in the basket

| pizza | extras |

| Aslak Hellesøy | - |

| Chris Matts | - |

And the “Aslak Hellesøy” pizza is selected from the basket

When I add extra cheese

And I add extra cucumber

Then the basket should contain

| pizza | extras |

| Aslak Hellesøy | +cheese +cucumber |

| Chris Matts | - |


How It's Made


Collaborate on requirements!

Well guided planning meeting can improve the “BDD-efficiency” quite much


Example Mapping

#0 – Choose a facilitator

• Someone needs to facilitate the discussion – not the PO

• The facilitation can be rotated so that everyone gets practice

• The facilitator can guide the discussion with• Asking questions

• Moderating (stopping?) discussions

• Everyone can ask of course…


#1 – Pick a guide line

• Choose a theme that you can use to order the questions

• The “sequence of actions” is usually good• ie. “What you do first?”

• If you use story mapping for planning the stories, this comes quite naturally


#2 – Keep collecting rules (acceptance criteria) and examples

• Once you hear an important rule/behavior/check, note it down as a rule and an illustrating example

• Don’t forget that an example is not necessarily text, but formulas, wireframes or anything that describes the required behavior

• Examples can help • understanding the topic

• discover misunderstandings

• keep the requirements real


#3 – Make notes visible to everyone

• Write them on index cards or stickies

• Using (and sharing on projector) a notepad, OneNote or SpecLog is also very good

• Pro: stored already in a searchable form, usually better visible (zoom), easy to go back to earlier notes

• Con: harder to get a full overview

• Stop the discussion while the rule/example is captured

• The team should have an agreement on the captured result

• Was this really what we were discussing about?


#4 – Collect questions

• If something cannot be answered or needs further research/investigation – capture it as a questions

• Captured questions can help • to avoid re-discussing the same topic again and again

• to have a clear list of topics we need to investigate


#5 – Split the story if necessary

• The map can help you to feel if the topics we have discussed are too much


+1 – Formulate the scenarios in Gherkin

• Not necessarily in the planning meeting

• Just before you start implementing the story works usually

• Don’t do it alone

• Try to find broader agreement especially for the first scenarios in a certain topic

• At this point, you are not discussing the behavior, but finalizing the ubiquitous language

What about my answers?





Who writes

the scenarios?How do you

set the title of

the scenario?

Can I have

multiple when/then

steps?


The answers

• Who writes the scenarios?• It does not matter, because we are all on the same page

regarding the behavior. But it makes sense if a developer is typing it in with a tester or PO sitting next to him/her.

• How do you set the title of the scenario?• You never set it, you start from the acceptance criterion that

will be the title.

• Can I have multiple when/then steps?• The scenario is the formalization of an AC – a simple check.

For that you usually need only one when step and only one or two then steps.


Try is at home!
