Features

Introduction#

You can use cucumber as a plugin in QTP and Selenium.

The steps in the cucumber scenario are global variables.

You can implement once and call many times. Hence reduces the code maintenance, and can reuse the same code when required.

Remarks#

Cucumber features are written in the Gherkin language and stored in files with the suffix .feature. This topic gives examples of each feature of Gherkin.

A minimal Cucumber feature

In features/documentation.feature:

Feature: Documentation

  Scenario: User views documentation
    When I go to the "Cucumber" documentation
    Then I should see the "Cucumber" documentation

A minimal feature has a Feature line and a Scenario with one or more steps beginning with When, Then or another Gherkin keyword.

A sensible scenario would probably have more than one step.

Scenario Outline

Template as below

Scenario Outline: As a homemaker i want to buy and pay for the below product
  Given I purchase <a product>
    And I require a carry bag to take things to home
  When I pay bill using <payment method> to successfully checkout
  Then I should have a receipt

Examples:
| a product     | payment method |
|  Cake         | Visa           |
|  Coke         | Paypal         |

Syntax Usage

Feature: Some terse yet descriptive text of what is desired
     Textual description of the business value of this feature
     Business rules that govern the scope of the feature
     Any additional information that will make the feature easier to understand

Background:
    Given some precondition needed for all scenarios in this file
        And another precondition

Scenario: Some determinable business situation
  Textual description of the business value of this scenario
  Business rules that govern the scope of the scenario
  Any additional information that will make the scenario easier to understand
    Given some precondition
      And some other precondition
    When some action by the actor
      And some other action
      And yet another action
    Then some testable outcome is achieved
      And something else we can check happens too
      But something else we can check does not happen

Scenario Outline: Some determinable business situation
    Given I am <precondition>
        And some other precondition
    When some action by the actor
    Then I have <outcome> rights

Examples:
    | precondition | outcome  |
    | username1    | customer |
    | username2    | admin    |

The following keywords are interchangable, but depending on context, may be better to use:
