Agenda

• Introduction
• Selenium
• Demo
• CruiseControl
• Showcase
• Conclusion

3
Share experience

• How do we test the web project?
• Whats our daily development like?
• Happy or painful?
• Why?
• Share your experience!

4

• Question 1
• Functional Test For Web app

5

• Traditional approach

Release
Development
Acceptance Testing
Regression Testing

• Developers have moved on
• Too close to release

6

• Faster feedback

Release
Development
Acceptance Testing
Regression Testing
Write test as you go
Problems are found quickly
Run them as often as you can
7
Why Automated?

• Manual testing is slow, tedious and error-prone
• Especially for regression

Either take long time or less thorough
What now? Start again?
8
Consistently Thorough Fast enough to start again
and again and again

Selenium
http//www.openqa.org/selenium/
10
Selenium

• Open source test tool for web applications.
• Run in browser
• Test browser compatibility system
  functionality.
• Easy to use.
• Test cases are written in pure HTML
• Clean and impressive UI

11
Demo

• Demo
• Start hsqldb
• Start tomcat
• Firefox
• http//localhost8080/jpetstore
• http//localhost8080/jpetstore/selenium

12

• Question 2
• Continuous Integration

13
What is Continuous Integration

• Integrates source code and runs tests after each
  commit of code to the source repository.
• Near-immediate feedback to the developer

14
Benefits of C.I.

• Minimizes integration risk.
• Supports easier defect diagnosis.
• Encourages good testing habit
• Support release management
• Enforces company development policy

15
CruiseControl
http//cruisecontrol.sourceforge.net/
Also see Luntbuild, which is a simpler analogue
of CruiseControl.
16
About CruiseControl

• Think of it as timer for Ant.
• Simple design. Full featured, but not bloated.
• Adapts to your project, not the other way around.
• Can be completely customized.

17
Build loop of C.C.
1. Bootstrap
2. Check for modifications
VCS
Cruise Control
3. Get the revision log
Build Artifacts Dir
5. Publish Artifacts
Mail/Sound/Light
6. Send to publisher
1. Get the latest source
4. Run Build
3. Tag source (optional)
Project Specific Adapter - Ant Script
Your projects Build file Ant, Maven, Make
2. Run Build

• Showcase

19
Conclusion

• DRY, use automation test/continuous tools help
  you improve your development process, and
  maximize customer value.
• Selenium helps you test webapp more easily.
• Keep CruiseControl running. it gives you feedback
  as soon as possible.
