The document discusses different types of software testing including unit testing, functional testing, and integration testing. It provides examples of implementing these different test types in various programming languages like PHP, Java, and Rails. It also covers important testing concepts like test data, mocking/stubbing, fixtures, and factories.

1. Testing

2. Test Driven Development
• Implementation
• Red-Green-Refactor
• Regression Tests

3. Implementation
• Test what should happen
• Test what should not happen

4. Red-Green-Refactor
Add a test
Run all tests
Write some code
Run the tests again
Refactor code

5. Regression Tests
Change environment
Change code
Is everything still working

6. Testing in php
$this->get(quot;http://myserver/login.phpquot;);
$this->assertWantedPattern(quot;Please login to continuequot;);
$this->setField(quot;usernamequot;, quot;MyTestUserquot;);
$this->setField(quot;passwordquot;, quot;t0ps3cr3tquot;);
$this->clickSubmit(quot;Loginquot;);
$this->assertWantedPattern(quot;You are logged inquot;);

7. Testing in Java
beginAt(quot;login.jspquot;);
assertTextInElement(quot;h1quot;, quot;Please login to continuequot;);
setFormElement(quot;usernamequot;, quot;MyTestUserquot;);
setFormElement(quot;passwordquot;, quot;t0ps3cr3tquot;);
submit();
assertTextInElement(quot;h1quot;, quot;You are logged inquot;);

8. Testing in Rails
visit login_path
assert_contain quot;Please login to continuequot;
fill_in quot;usernamequot;, :with => quot;MyTestUserquot;
fill_in quot;passwordquot;, :with => quot;t0ps3cr3tquot;
click_button quot;Loginquot;
assert_contain quot;You are logged inquot;

9. Test Types
• Unit
• Functional
• Integration

10. Unit
• Most basic level of testing
• Model tests in Rails

11. Unit Testing
class ShipTest
class Ship
def test_crew
attr_accessor :captain
ship = Ship.new
attr_accessor :maties
ship.captain = 1
ship.mateys = 20
def crew
captain + maties
assert_equal 21, ship.crew
end
end
end
end

12. Functional
• Test lifecycle of objects
• Controller tests in Rails

13. Functional Testing
class ShipsController
def enter_other_ship
@ship = Ship.find_captain(params[:captain])
@ship.gold += 1000
@ship.save
redirect_to :action => 'show_loot'
end
end class ShipsControllerTest
def test_entering_other_ship
post 'enter_other_ship', :captain => quot;Sparrowquot;
assert_response :redirect
assert_equal quot;Black Pearlquot;, assign(:ship).name
assert_equal 1000, assigns(:ship).gold
end
end

14. Integration
• Overall application functionalities
• Walk through a series of events
• View Tests / Stories

15. Integration Testing
def test_attacking_other_ships
Given quot;another shipquot; do |ship|
@ship_to_enter = Ship.find(ship)
end
Given quot;my shipquot; do
Story: Attacking other ships @my_ship = Ship.find_by_captain(quot;Sparrowquot;)
As Captain Sparrow end
I attack another ship
So I can buy more rum Given /my $number_of_mateys maties/ do |number_of_mateys|
@ship_to_enter.attackers = number_of_mateys
end
Scenario: Attack first ship
Given another ship When quot;we attach the other shipquot; do
And my ship @my_ship.attacks(@ship_to_enter)
And my 20 mateys end
When we attack the other ship
Then 1 pirate dies Then /$pirates_lost pirate dies/ do |pirates_lost|
assert_equal @my_schip.crew - pirates_lost, @ship_to_enter.attackers
And we steel 1000 pieces of gold
end
Then /we steel $pieces_of_gold pieces of gold/ do |pieces_of_gold|
assert_equal pieces_of_gold, @my_ship.gold
end
end

16. Integration Testing
Story: Attacking other ships
As Captain Sparrow
I attack another ship
So I can buy more rum
Scenario: Attack first ship
Given another ship
And my ship
And my 20 mateys
When we attack the other ship
Then 1 pirate dies
And we steel 1000 pieces of gold

17. def test_attacking_other_ships
Given quot;another shipquot; do |ship|
@ship_to_enter = Ship.find(ship)
end
Given quot;my shipquot; do
@my_ship = Ship.find_by_captain(quot;Sparrowquot;)
end
Given /my $number_of_mateys maties/ do |number_of_mateys|
@ship_to_enter.attackers = number_of_mateys
end
When quot;we attach the other shipquot; do
@my_ship.attacks(@ship_to_enter)
end
Then /$pirates_lost pirate dies/ do |pirates_lost|
assert_equal @my_schip.crew - pirates_lost, @ship_to_enter.attackers
end
Then /we steel $pieces_of_gold pieces of gold/ do |pieces_of_gold|
assert_equal pieces_of_gold, @my_ship.gold
end
end

18. Test Data
• Mock/stub
• Fixtures
• Factories

19. Mocking & Stubbing
def test_getting_tweet_on_homepage
response = mock
response.stubs(:authorization).returns(true)
response.stubs(:last_tweet).resturns(quot;#arrrrcamp rocksquot;)
TwitterAPI.expects(:get_last_tweet).returns(response)
get 'index'
assert_equal quot;#arrrrcamp rocksquot;, assigns(:tweet).body
end
- Mocha
- Rspec
- Flex Mock

20. Fixtures
pirates.yml ships.yml
captain_jack_sparrow: black_pearl:
name: Jack Sparrow name: The Black Pearl
enemy: Royal Navy max_crew: 85
captain: captain_jack_sparrow
interceptor:
name: The Interceptor
max_crew: 150
captain: captain_jack_sparrow

21. Factories
Factory.sequence :pirate do |n|
quot;matey#{n}quot;
end
Factory.define :ship do |f| should quot;only find big shipsquot; do
f.name 'Pirateship' Factory(:ship, :max_crew => 500)
f.max_crew 100 Factory(:ship, :max_crew => 200)
f.captain { Factory.next(:pirate) }
end ships = Ship.big_ones
assert_equal 1, ships.size
end
