How to write a Behat test
Confident coding? Skip to here:
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 recommended. 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.
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 achievable 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 . These are your 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 (Bug 1234) Given I am logged in as the user "admin" with password "Password1" And I follow "Portfolio" # 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"
Save the test as a .feature file in the right directory. For example, portfolio_page.feature
The fastest way to write a test is using parts from previous tests. In the terminal use this command to search for the specific steps that you need:
grep --color=auto -RniP -C 3 --include *.feature '(given|when|then|and).*delete.*activity' *
Replace delete and activity with the specific things that you need to search for
