Given when then (new)

The idea behind Cucumber is to test the behaviour of an application. This usually involves SMART user stories created with the stakeholders. Therefore, they must be non-technical, short and easily rearrangeable. But, they must also be testable. The Given-when-then keywords make sure scenarios are testable while providing great guidance to stakeholders.

Given

The Given keyword is used to set up the starting condition of the scenario. This can be a webpage, a GUI window, a logged in user, some data to be used in the tests etc.

Examples:

Given I am in the cucumber wiki

Given I have the following movies: |title |rating| |Men in Black|PG-13 |

Given I am on the Invoice window ##When The When keyword specifies an action performed by the user in the given starting condition. It can involve following a link, clicking a button etc.

Examples:

When I follow the "Add Page" link

When I press the "Find Movie" button

When I fill the quantity with 5 ##Then The Then keyword defines the expected behaviour, i.e. what should happen when those conditions are met and this action is performed.

Examples:

Then I should be on the "Add Page" page

Then I should see the movie titled "Men in Black"

Then my total should be updated
