Data tables and Screenshots in Cucumber

Cucumber Tests can be enhanced with features like data tables, screenshots. These features can help you make tests more robust and easier to understand.

Data tables: Data tables can be used to provide input data for your Cucumber tests. Data tables can be defined in .feature files or can be external files. Data tables can be used to test different input values or run the same scenario with varying data sets.

Scenario Outline: Check login functionality Given I am on the login page When I enter "<username>" and "<password>" Then I should be logged in successfully Examples: | username | password | | Anshita | 123456 | | Alice | qwerty |


This helps us reduce the Test Scenario Effort. Normal way of writing Scenario for the above Example would be 2 Test cases

Scenario: Check login functionality for multiple users


Given I am on the login page When I enter "Anshita" and "123456" Then I should be logged in successfully

When I enter "Alice" and "qwerty" Then I should be logged in successfully


Thus Data Tables helps Optimize the Test cases.


Data Tables can also be used to send the values for the multiple fields by specifying it in the table

Scenario: Check Forms functionality Given User on the Forms page When User enters <”Field”> Values

And User Click “Save” button | Field |

| Anshita| | Alice |

Screenshots

Another way to enhance Cucumber tests is to take screenshots. Screenshots can help debug purposes or for creating reports. Embed method to take a screenshot in Cucumber. The embed method takes a screenshot and embeds it in the HTML report.

Here is an example of how to use the embed method:

Scenario: Login feature

Given I am on the login page

When I enter my username and password

Then I should be logged in

And I take a screenshot


def take_screenshot

embed("screenshot.png", "image/png")

end

In this example, the take_screenshot method takes a screenshot and embeds it in the HTML report. The method takes a screenshot of the login page and saves it as a png file.
