What is Behavior Driven
Development?
Behaviour-driven development is an “outside-in” methodology. It starts at the outside by identifying business outcomes, and then drills down into the feature set that will achieve those outcomes. Each feature is captured as a “story”, which defines the scope of the feature along with its acceptance criteria.
Dan North, “What’s in a Story”http://dannorth.net/whats-in-a-story
It’s the idea that you start by writing human-readable sentences that describe a feature of your application and how it should work, and only then implement this behavior in software.
Behat Documentationhttp://docs.behat.org/en/v2.5
BDD is not about...
Well Designed CodeAutomated TestingImplementationUI Testing
Why Practice Behavior Driven
Development?
“You can turn an idea for a requirement into implemented, tested, production-ready code simply and effectively, as long as the requirement is specific enough that everyone knows what’s going on.”
Dan North, “What’s in a Story”http://dannorth.net/whats-in-a-story
GherkinBusiness Readable (Writable?), Domain Specific Language

Story: Feature Fileone Feature with a narrative
one or more Scenarios
Acceptance Criteria: Scenarios
Narrative
As a [role]I want [feature]So that [benefit / business reason]
Use “5 Whys” to determine narrative
Feature: Account Holder Withdraws CashFeature: Short, Descriptive, Action
Acceptance Criteria: Scenarios
Given: Exact Context
When: Action/Event
Then: Outcomes
And/But: More of the same...
Scenario: Account has sufficient fundsGiven the account balance is $100And the card is validAnd the machine contains enough moneyWhen I request $20Then the ATM should dispense $20And the account balance should be $80And the card should be returned
Scenario: Account has insufficient fundsGiven the account balance is $10And the card is validAnd the machine contains at least the amount of my balanceWhen I request $20Then the ATM should not dispense any moneyAnd the ATM should say there are insufficient fundsAnd my account balance should be $10And the card should be returned
Scenario: Card has been disabledGiven the card is disabledWhen I request $20Then the ATM should retain the cardAnd the ATM should say the card has been retained
As an Account Holder I want to withdraw cash from an ATM So that I can get money when the bank is closed
Gherkin Keywords: Auto-Generated StepsYou can implement step definitions for undefined steps with these snippets: /** * @When /^I select Texas from the states list$/ */ public function iSelectTexasFromTheStatesList() { throw new PendingException(); } /** * @Then /^I should see the list of services offered$/ */ public function iShouldSeeTheListOfServicesOffered() { throw new PendingException(); }
BDD is about...
Communication CollaborationDocumentationPreventing User-Facing
Regressions
Writing Features
Feature: View Countdown before Broadcast As a user viewing a broadcast page before the broadcast starts I want to see a countdown timer So that I can know how long until the broadcast actually starts
Scenario: View Countdown before Broadcast
Given I view the “Future Broadcast” broadcast Then I should see "Future Broadcast" on the pageAnd I should see "Future Broadcast Author" on the pageAnd I should see "This broadcast begins at 6:00 pm EST" on the pageAnd I should see a countdown timer
ProcessAuthor describes Feature
with implementation specific example
Developer adds fixture data
IssuesTest only works before 6pmWhat is the intent?Confusion for business users
Feature: View Countdown before Broadcast As a user viewing a broadcast page before the broadcast starts I want to see a countdown timer So that I can know how long until the broadcast actually starts
Scenario: View Countdown before Broadcast
Given there is a broadcast scheduled for the futureWhen I view that broadcast’s pageThen I should see the broadcast titleAnd I should see the broadcast author’s nameAnd I should see "This broadcast begins at" followed by the start time in ESTAnd I should see a countdown timer
ChangesGiven now explains exact
contextTest is no longer time-
dependentIntent - not implementationWhy?Overall understandingCommunication valueHelp identify poorly written
code
Feature: Customer Views Product and Services Catalog As a customer I want to view the product catalog So that I can browse products and services
Scenario: Customer views Product CatalogGiven I view the catalogWhen I select "Texas" from the list of statesThen I should see the list of products for sale
Scenario: Customer views Local Services in Product CatalogGiven I view the catalogWhen I select "Texas" from the list of statesThen I should see the list of services offered
IssuesWhat is the intent?Is Texas relevant?
Feature: Customer Views Product and Services Catalog As a customer I want to view the product catalog So that I can browse products and services
Scenario: Customer views Product CatalogGiven I view the catalogWhen I select "Texas" from the list of statesThen I should see the list of products for sale
Scenario: Customer views Local Services in Product CatalogGiven I view the catalogWhen I select "Texas" from the list of statesThen I should see the list of services offered
IssuesWhat is the intent?Is Texas relevant?
if not: implementation detail
Scenario: Customer views Product CatalogGiven I view the catalogWhen I select a state from the list of statesThen I should see the list of products for sale
Scenario: Display Local Services in Product CatalogGiven I view the catalogWhen I select a state from the list of statesThen I should see the list of services offered

Scenario: Customer views Local Services in Product CatalogGiven I view the catalogWhen I select "Texas" from the list of statesThen I should see the list of services offered
IssuesWhat is the intent?Is Texas relevant?
if not: implementation detailif yes: uncover business value
and context
Scenario: Customer views Product CatalogGiven I view the catalogWhen I select a state from the list of statesThen I should see the list of products for sale
Scenario: Display Local Services in Product CatalogGiven the company has a regional office in a stateWhen I view the catalogAnd I select that state from the list of statesThen I should see the list of services offered
Feature: Customer Views Product and Services Catalog As a customer I want to view the product catalog So that I can browse products and services

Scenario: Customer views Local Services in Product CatalogGiven I view the catalogWhen I select "Texas" from the list of statesThen I should see the list of services offered
NarrativeUse narrative to explain
business value for featureNot processed in Behat 2.5Behat 3.0+ role can be used
to specify which context files are used
Feature: Customer Views Texas-Specific Catalog As a customer in Texas I want to view the products and services for sale in Texas So that I can buy them
Scenario: Display Local Services when viewing Texas
Given I view the catalogAnd I select Texas from the list of statesThen I should see the products for sale in TexasAnd I should see the list of services offered in Texas
ImplementationWhen I select "Texas" from the states list
/*** @When /^I select "([^"]*)" from the states list$/ */public function iSelectFromTheStatesList($arg1){}
IntentWhen I select Texas from the states list
/*** @When /^I select Texas from the states list$/*/public function iSelectTexasFromTheStatesList(){}
Demonstrate Intent by Removing Variables
Shows specific intent rather than an example of behavior
Indicates there is an important business value to the state
Impossible for anyone to plug in another state
Feature: Customer Views Product and Services Catalog As a customer I want to view the product catalog So that I can browse products and services
Scenario: Customer views Product CatalogGiven I view the catalogWhen I select a state from the list of statesThen I should see the list of products for sale
Scenario: Display Local Services in Product CatalogGiven the company has a regional office in a stateWhen I view the catalogAnd I select that state from the list of statesThen I should see the list of services offered
echo '<h1>Products</h1>';foreach ($products AS $product) { echo '<p>' . $product->getName() . '</p>';}
echo '<h1>Services</h1>';foreach ($services AS $service) { echo '<p>' . $service->getName() . '</p>';}
Scenario: Don’t Display Local Services in Product Catalog For States With No Regional Office
Given the company does not have a regional office in a stateWhen I view the catalogAnd I select that state from the list of statesThen I should not see a list of services offered
Feature: Customer Views Product and Services Catalog As a customer I want to view the product catalog So that I can browse products and services
