1.1. JUnit
 From xUnit generic term: a framework to test the
smallest part of a code.
 For Java: class, interface.
 It aims at repeatable tests: checking that code’s
evolution do not alter the specification compliance.
 Integrated in Eclipse, NetBeans…
 Content:
 Assertions for testing expected results
 Test fixtures for sharing common test data
 Test runners for running tests

import junit.framework.TestCase; @Before
import org.junit.*; public void setUp() throws Exception {
// Code executed before each test
public class TestFoobar extends }
TestCase{
@BeforeClass @After
public static void setUpClass() public void tearDown() throws Exception {
throws Exception { // Code executed after each test
// Code executed before the }
first test method }
@Test
@AfterClass public void test() {
public static void assertTrue(true);
tearDownClass() throws Exception }
{ }
// Code executed after the last
test method
} 4

1.2. Selenium
 Test web applications
 It records a previous test and plays it anytime it would be
necessary in order to test the webapp
 It has its own programming language (Selenes) in order to
program tests in most popular languages:
 C#, Java, Groovy, Perl, PHP, Python & Ruby.
 Tests can be executed in any web browser and any platform
5

6.
1.2. Selenium
 Its architecture is based on:
 Selenium IDE:
▪ Firefox Extension which lets to record, edit and
debug tests
▪ It lets to export created tests into different
programming languages
 Selenium RemoteControl
▪ Java Server which interprets commands via
HTTP
 Selenium Client API
▪ Selenese
6

7.
 Its purpose is to assure the main demands of the industry
nowadays:
 Value:
▪ Value at the moment of product launch
▪ Ability to adapt and evolve through upgrades and expansions
 Reduced development time:
▪ Overlapping in development phases
▪ Early delivery of the first parts of the product which are often the most urgent
 Quickness:
▪ Produce complete parts of the product in short periods of time
 Flexibility:
▪ Adjust the shape and course of project development characteristics and evolution of
requirements
 Reliability:
▪ The processes are good when they get delivered early and continuously innovative value
7

8.
 Agile Software Development cycle is
divided into:
 Concept:
▪ Create the vision of the product
▪ Determine what the team is going to work on
 Speculation:
▪ Determine limitations imposed by business
environment: agendas and costs
▪ Close first approximation about what it can be
produced
 Exploration:
▪ Develop an increment of the product which includes
those functionalities determined in previous phase
 Revision:
▪ Revision what it has been built until this moment
 Closing:
▪ It does not imply the end of the project

9.
 Most popular Agile Software Development models are:
 Adaptive Software Development (ASD)
 Agile Unified Process (AUP)
 Crystal Clear.
 Essential Unified Process (EssUP)
 Feature Driven Development (FDD)
 Lean Software Development (LSD)
 Kanban
 Open Unified Process (OpenUP)
 eXtreme Programming (XP)
 Dynamic Systems Development Method (DSDM)
 Scrum

10.
2.1. Scrum
 Very simple development methodology:
 It requires hard work  there’s no plan, only continuous adaptation of the
project
 All the people which participate in the project are classified in:
 Committed (pigs)
 Involved (hens)
 Meetings:
 They must be done stood
 It is advisable to use a cell format tasks on a blackboard
 A graph indicating the improvements done in the sprint should be there
 Meetings Type:
 Sprint planning
 Sprint track
 Sprint review

3.1. Control Version tools
 Apache Subversion (SVN):
 How you manage several versions due to different programmers?
 Started as early as mid 70’s.
 SVN’s ancestor is CVS: Concurrent Version System, started as shell scripts
in 1986.
 SVN was born in 2000 to complete and develop CVS
 Today, it is a top-level Apache project.

13.
1 – Get content:
svn checkout
svn update
2 – Make changes:
svn add
svn move
svn delete
3 – See what was changed in the
repository in meantime
svn status -u
4 – Update your local copy
svn update
5 – Merge your changes and Resolve
conflicts
svn diff
svn resolved
6 – Submit your changes
svn commit
13

14.
 Conflicts resolution:
 svn diff  show the differences from the
checkout files
 svn revert  cancel all modification( except
deleted files), then update & work again. Svn does
not know how to merge binary files (.doc).
 svn resolved <FileName> then commit again
 svn automatically merge (fusion) if modifications
are not at the same place.

15.
3.1. Control Version tools
 GIT: distributed version control, since 2005, by Torvalds for
Linux kernel.  created by programmers for programmers !!
• Only working copies
• Faster operation (no central
server)
• Autonomous group of
developers from network and
chiefs.
• Private versioning.
• Still possibility to have a central
server.
15

16.
3.2. Maven :
 Maven: project
management and
build automation
 Only direct
dependencies
 Scope
specification
(JUnit only for
test)
16

17.
 Project described in the POM file, Project Object Model. XML, and
v3.0 Ruby, Groovy or Yaml.
 Contents:
 Src and resource files location
 Java version
 Direct dependencies
 Used plugins
 Technical report asked
<project>
<modelVersion>4.0.0</modelVersion>
<groupId>com.mycompany.app</groupId>
<artifactId>my-app</artifactId>
<version>1.0</version>
</project>
17

18.
 Convention over Configuration: specified only the
unconventional.
 Build life cycles:
 process-resources
 compile
 process-test-resources
 test-compile
 test
 package
 install
 Deploy
 mvn test  all the way until test.

19.
3.3. Hudson
 Continuous Integration Tool implemented in Java
 It works over an application server such as Apache or GlassFish
 It supports control version tools (CVS, SVN, GIT)
 It can execute projects based in Apache Ant or Maven, and
scripts based on batch or shell/bash scripts
 It can build the projects through:
 A scheduler programmed with cron
 Compilation of other projects
 Request of an specific URL
19

20.
3.3. Hudson
 Principals advantages:
 Easy installation and use: deploy a .war and easy web interface
 An extensible plugin system
 Support for distributed compilation based on master-slave systems
 Support for multiples machines and project groups
 It is completely Free Software
