introduce cucumber

Why should we use automatic test framework?

A long long story…

Why should we choose

?

Test Driven Development

cCan you understand it?

No, I can’t

Behavior Driven Development

Feature: Now User has given all his basic info and decided which products he will buy, then he forward into the last process - pay the money. /registration/business_pay will summarize the price(including tax and discount) he will pay and let user fill in his credit card info, when he presses "Confirm", it will charge his credit card.

Scenario: Now user input credit card info and press "Confirm", the page will submit his info to AriaSystem, AriaSystem will validate his credit card info, charge his credit card and return some data to our database. Then our database will save his personal info and partner info. If all these work well, user will be redirected to /registration/business_finish.

Given I reach /registration/business_pay When I fill in basic info into /registration/business_pay And I press "Confirm" Then I should see "Please wait..." And I waiting for being redirected to "/registration/business_finish" And all MozyPro data in Database is correct

Everyone can read it

Everyone can write it

Include people who don’t speak English

How does it test?

Open a real browser

Behave as a real user

Apply to any page, any website

Not only BDD

But also DDD

Document Driven Development

Cucumber Style Document

More secrets ?

Step Definitions

Given /^I am in "([^"]*)"$/ do |url|visit mozy_url(url, :https => true)

end

Then /^I would be redirected to "([^"]*)"$/ do |url|page.current_url.should be_include?

mozy_url(url, :https => true)end

Have a try ?

Let’s write a simple Cucumber test case

Sign up an Account

Gemfile

group :test do gem 'cucumber' gem 'cucumber-rails', require: false gem 'capybara', git: 'https://github.com/jnicklas/capybara.git' gem 'rspec' #use rspec expectation gem 'Selenium' #use firefox to test gem 'database_cleaner' #clean database after each test caseend

$ bundle install

Install Cucumber$ rails generate cucumber:install create config/cucumber.yml create script/cucumber chmod script/cucumber create features/step_definitions create features/support create features/support/env.rb exist lib/tasks create lib/tasks/cucumber.rake gsub config/database.yml gsub config/database.yml force config/database.yml

features/support/env.rbrequire 'cucumber/rails’

Capybara.default_selector = :cssCapybara.default_driver = :selenium #add this line

ActionController::Base.allow_rescue = false

begin DatabaseCleaner.strategy = :transactionrescue NameError raise "You need to add database_cleaner to your Gemfile (in the :test group) if you wish to use it."End

Cucumber::Rails::Database.javascript_strategy = :truncation

features/sign_up.featureFeature: Sign up

Scenario: I will register a user with email "zhour@vmware.com" and password "vmware”

Given I fill in email "zhour@vmware.com" and password "vmware" in sign up page When I press "Sign up" Then I should see "Page#index"

$ rake cucumber

features/step_definitions/sign_up.rb

it works

Firefox

Thanks
