Feature: Short summary title
As a common user
I want to be able to do something
So that I have a profit
Scenario: Particular case
Given some precondition
And some other precondition
When some action is done by user
And some other action
And yet another action
Then some testable outcome is achieved
And something else we can check happens too
Prepare Act Assert

5. Step Definitions & Runners

package myprecious.tests.cucumber.steps;
public class CertainSteps {
@Given("^some precondition$")
public void step_definition() {
... //My code here
}

6. WHAT CAN
A SCENARIO
DO?
04.11.2014 / 6

7. Hooks
04.11.2014 / 7
Feature: Payment operations
@ui
Scenario: Make payment using current card
Given I have logged
And I have selected card
...
@service
Scenario: Get internal payment info
Given I have submitted payment :
...
public class TaggedHooks {
@Before("@ui")
public void startUpUi() {
//open browser ...
}

public void clearUi(Scenario scenario) {
if (scenario.getStatus().equals("failed")) {
byte[] screenshot = ((TakesScreenshot)driver).
getScreenshotAs(OutputType.BYTES);
scenario.embed(screenshot, "image/png");
}
OR (“@ui, @service”)
AND ({“@ui”, “@service”})

14. HOW CAN WE MAKE IT BETTER?
04.11.2014 / 14

15. Integrate
04.11.2014 / 15
Maven failsafe plugin to launch the tests.
Test reports passed in json to Jenkins Cucumber report plugin.

16. Use the power
04.11.2014 / 16
Backgrounds, examples, regexps …
Given I am on the advanced search page
And I select "Endocrinology" from "Specialty"
And I choose "Yes" within "Accepts Insurance"
And I fill in "ZIP Code" with "90010"
And I select "5 miles" from "Search Radius"
When I press "Search"
When I search for a provider with the criteria:
| Provider Type | Doctor |
| Specialty | Endocrinology |
| Accepts Insurance | Yes |
| ZIP | 90010 |
| Search Radius | 5 miles |
When I search for a provider with the default criteria and:
| Specialty | Endocrinology |
| Accepts Insurance | No |
...
When I search for a provider with the default criteria
Then the search criteria should include:
| Provider Type | Doctor |
| Specialty | General |
| Accepts Insurance | Yes |
| ZIP | 90010 |
| Search Radius | 5 miles |

17. Use the power … of regexps?
04.11.2014 / 17
When I use email (?:[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:.[a-z0-
9!#$%&'*+/=?^_`{|}~-]+)*|"(?:[x01-x08x0bx0cx0e-x1fx21x23-x5bx5d-x7f]|[x01-
x09x0bx0cx0e-x7f])*")@(?:(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?.)+[a-z0-
9](?:[a-z0-9-]*[a-z0-9])?|[(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-
9]?).){3}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?|[a-z0-9-]*[a-z0-
9]:(?:[x01-x08x0bx0cx0e-x1fx21-x5ax53-x7f]|[x01-x09x0bx0cx0e-x7f])+)])
When I am logged in
...
When I am logged in as "Joda"
@Then("^I am logged in$")
.* Anything or nothing
.+ Something
d* none or more digits
d+ some digits
"[^"]*" Something in quotes
an? Something optional
...
@When("^(?:I am logged|I log) in as an? "([^"]*)"$")
@Then("^(?:receipt has )?following payment (?:information|info) :$")

18. Choose your domain
04.11.2014 / 18
Scenario: User with valid credentials
Given an unauthenticated user
When the user tries to navigate to the welcome page
Then they should be redirected to the login page
When the user enters a valid name in the Name field
And the user enters the corresponding password in the Password field
And the user presses the Login button
Then they should be directed to the welcome page
• Security domain, user authentication
• Password based authentication domain
• UI widgets domain
• Domain of web assets
Scenario: User with valid credentials
Given an unauthenticated user
When the user tries to access a restricted asset
Then they should be directed to a login page
When the user submits valid credentials
Then they should be redirected back to the restricted content
• “WHAT”  User authentication domain
• “HOW” Web based security domain

19. Declarative vs. Imperative
04.11.2014 / 19
How exactly to do it ?What should be done?
Scenario: Successful login
Given a user "Smith" with password "qwerty"
And I am on the login page
And I fill in "User name" with "Smith"
And I fill in "Password" with "qwerty"
When I press "Log in"
Then I should see "Welcome, Smith"
Background:
Scenario: Successful login
Given a user "Smith" with password "qwerty"
And I am on the login page
And I fill in "User name" with "Smith"
And I fill in "Password" with "qwerty"
When I press "Log in"
Then I should see "Welcome, Smith"
Scenario: User is greeted upon login
Given the user "Smith" has an account
When he logs in
Then he should see "Welcome, Smith"
Background: The user is logged in
Given a logged in user
Feature: The System
Scenario: Everything Works
Given the system exists
When I use it
Then it should work, perfectly
