What is the "Background" keyword in Cucumber feature file
When we are writing Feature file in cucumber, we write multiple Scenarios. All scenarios start with a particular point. Suppose I am writing the feature file called home_page_facebook and the number of scenarios is there to check the home page functionality. Now if you think about any scenario then you need to login first on the facebook page to reach to the home page. So it is better to write all common or repeated step in one place rather than in all scenarios. To achieve this situation we need to add "Background" keyword in the feature file. Let's understand with an example.
Feature file : home_page_facebook.feature
Feature: In order to test the home page of the application as a registered user I want to specify the features of the home page.
Scenario : Home page default contents.
Given user on application landing page.
When user enter password
And user enter username
And user click on login button
Then user navigates to application home page.
And user validate default contents of home page
Scenario : Top banner settings option.
Given user on application landing page.
When user enter password
And user enter username
And user click on login button
Then user navigates to application home page.
When user click on the setting other
Then user get the logout option
There is 2 scenario where you can see login steps are common to both the scenarios. So we can eliminate the common section and put it into a commonplace.
So I am rewriting the feature file with the Background keyword.
Feature file : home_page_facebook.feature
Feature: In order to test the home page of the application as a registered user I want to specify the features of the home page.
Background: Flow till home page
Given user on application landing page.
When user enter password
And user enter username
And user click on login button
Then user navigates to application home page.
Scenario : Home page default contents.
Then user validate default contents of home page
Scenario : Top banner settings option.
When user click on the setting other
Then user get the logout option
Now you can see login steps are in the commonplace.
There we use Background keyword. All steps mentioned in the Background keyword will be executed before every scenario or scenario outline.
I have provided all my glue code and cucumber feature which I have written in eclipse.
