Using Scenario Outline
Cucumber inherently supports data driven testing using Scenario Outline. Consider the following feature file using Scenario to define the test steps-
Feature: Check addition in Google calculator
In order to verify that google calculator work correctly
As a user of google
I should be able to get correct addition result
Scenario: Addition
Given I open google
When I enter "2+2" in search textbox
Then I should get result as "4"
In order to make it data driven we just have to use Scenario Outline along with Examples. Write the following code in feature file-
Feature: Check addition in Google calculator
In order to verify that google calculator work correctly
As a user of google
I should be able to get correct addition result
Scenario Outline: Addition
Given I open google
When I enter "<calculation>" in search textbox
Then I should get result as "<result>"
Examples:
| calculation |result|
| 3+3 | 6 |
| 2+5 | 70 |
Now the test would run twice with two different set of values. Check the parameterization done in scenario- “When I enter “<calculation>” in search textbox”, instead of hard coding the test data, variables are defined in Examples section and used in Scenario Outline section. Also, note that the step definition file will remain same and will require no change for scenario outline.
