Agenda

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

Share experience

• How do we test the web project?• What’s our daily development like?• Happy or painful?• Why?

• Share your experience!

Question #1:

Functional Test For Web app

Traditional approach

Development Acceptance Testing Regression Testing

Release

Feature developed Bug found! Regression found!

• Developers have moved on

• Too close to release

Faster feedbackDevelopment

Acceptance Testing

Regression Testing

Release

Write test as you goRun them as often as you canProblems are found quickly

Why Automated?

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

Regression Testing

3 months

Either take long time or less thoroughWhat now? Start again?

Regression Testing

10 minutes

Consistently Thorough

Fast enough to start again and again and again…

Selenium

http://www.openqa.org/selenium/

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

Demo

• Demo– Start hsqldb– Start tomcat– Firefox

• http://localhost:8080/jpetstore• http://localhost:8080/jpetstore/selenium

Question #2:

Continuous Integration

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

Benefits of C.I.

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

policy

CruiseControl

http://cruisecontrol.sourceforge.net/

Also see Luntbuild, which is a simpler analogue of CruiseControl.

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.

Build loop of C.C.

VCSBuild Artifacts Dir

Mail/Sound/Light…

1. Bootstrap

2. Check for modifications

3. Get the revision log

Cruise Control

Your project’s Build file

Ant, Maven, Make2. Run Build

5. Publish Artifacts

6. Send to publisher1. Get the latest source3. Tag source

(optional)

Project SpecificAdapter -Ant Script

4. Run Build

• Showcase

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.
