CUCUMBER –Making BDD Fun

Question: One of main constituents of a salad?
Answer: SURE!!!
But that’s not what we are here for!!!
What is Cucumber?

Behavior Driven Development and testing tool
Bunch of behaviors in the form of scenarios
Written mainly by non-technical people
Written in plain english
What is Cucumber actually?

Write a behavior in the form of scenario in a feature file
Write the code in order to satisfy the scenario(the actual application and not the automation script)
Run the feature file
Watch it fail
Write the automation script with the template provided by cucumber
The behavior of the application is satisfied by the test script
What should you actually do?

I am sorry but I am not going to discuss the merits and demerits of BDD
Behavior Driven Development?

Project root/
Features
fileName1.feature
fileName2.feature
Support
Env.rb
Step_definitions
fileName1.rb
fileName2.rb
Directory structure

Feature: Title
As a [role]
I want [feature]
So that [benefit]
Scenario: Title
Given [context]
When [event]
And [more event]
Then [outcome]
And [another outcome]
Lets get straight to it!!!

What the @#$% !!!

Feature: Login
As an admin
I want be able to login with my credentials
So that I get to the home page
Scenario: Able to successfully login
Given that I am on page “http://www.blahblah.com”
When I provide my username “admin”
And I provide my password “admin”
Then I should be at “HomePage”
Example

Develop the application driven by the behavior described earlier in the feature file
Develop!!!

$ cucumber login.feature
RUN the damn thing….

Run and watch it fail…

A template provided in order to write the automation script

They are called step definitions
Essentially bunch of ruby code
A library called Watir is used for the API
What was that?

Run it again….
What next….

Watch it fail again…

Go back to step definitions and write the script in order to satisfy the behavior

Keep on running the feature file until all of them turns green like a Cucumber

?
Thank You!!!
