How to write a Behat test

Confident coding? Skip to here:[1]

Behat tests are written in Gerkin language, which is English readable. You write the test in a text editor like Vim, Gedit or Eclipse. For beginners, Gedit is reccomended. Open your editor. To write the test start with the feature. The purpose of the Feature is to say what you are testing and what you gain from testing that feature.

 Feature: Creating a Portfolio page <- (the point of the test)
 In order to have a portfolio page in Mahara <- (What you are wanting to do)
 As an admin <- (Who you are logging in as eg student, admin, institution admin)
 So I can save my work on my Portfolio page <- (How you benefit from it)

The Scenario states what you are doing to test that feature. If you are testing a specific bug add the bug number here from Launchpad.

 Scenario: Creating a Portfolio Page (Bug 1234) <- (Describe what you are about to do to test it works) 
 Given (Setting the scene, these are you pre conditions)
 # Comment (Comments are milestone markers to make it human readable) 
 And  (Use as many And's as you need to set the pre conditions)
 When (This is an action you do like clicking or pressing a button)
 And  (Use as many And's as you need to describe the action you are doing like pushing 10 buttons to get to the place you want)
 # Comment (Adding a comment here to make it readable, describing what I am doing)  
 Then (This is the achieveable outcome. Often it's what you see when the link you clicked worked.) 
 And  (Use as many And's as you need) 

Write down every link you click and every button you pushed to create the page using the specific Behat syntax from this page [2]. These are you Given, And, When and Then steps.

Behat test example:

 Feature: Creating a Portfolio page 
 In order to have a Portfolio Page in Mahara
 As an admin
 So I can save my work on my Portfolio page

Scenario: Creating a Portfolio page 
 Given I am logged in as the user "admin" with password "Password1"
 And I follow "Porfolio"
 # Creating a page 
 And I follow "Pages"
 When I press "Create page"
 # Filling in the information on the page
 And I fill in the following:
 | Page title | This is where you put the title of the page |
 | Page description | This is where you type the description of the page |
 # Saving the page
 And I press "Save"
 And I press "Done"
 # Verifying that the page saved  
 Then I should see "This is where you put the page title"
