Cucumber is a BDD (Behavioral Driven Development) testing framework. A Scenario outline is similar to the test data corresponding to a test scenario. Scenario is one of the core Gherkin structures. Hooks are blocks of code that run before or after each scenario in the Cucumber execution cycle. every feature will have one or more scenarios and each scenario consists of one or extra steps.

This allows us to manage the code workflow better and helps to reduce code redundancy. Features file contain high level description of the Test Scenario in simple language. Cucumber supports Data Driven Testing using Scenario Outline and Examples keywords. The given user navigates to Facebook. You can ignore Cucumber Tests using tags. Scenario includes all the possible circumstances of the feature and test scripts for these circumstances. Cucumber came with a solution for reducing this effort by using the concept of Scenario Outline coupled with Examples. It allows you to add some context to the scenarios for a feature where it is defined. Based from Gherkin Reference, the Scenario Outline keyword can be used to repeat the same steps with different values or arguments being passed to the step definitions. Creating a feature file with Scenario Outline and Example keywords will help to reduce the code and testing multiple scenarios with different values. You might also like Getting Started With BDD In Behave Using Python. You need 2 Files – Features and Step Definition to execute a Cucmber test scenario. Scenario outlines allow us to more concisely express these examples through the use of a template with placeholders, using Scenario Outline, Examples with tables and < > delimited parameters. Scenario 3: Enter login Credential on Guru99 & reset the value. #8) Cucumber Reporting. For this, Gherkin provides one more structure, which is scenario outline.
