Question #1: Functional Test For Web app

Question #1:

Functional Test For Web app

Traditional approach Development Acceptance Testing Regression Testing Release Developers have moved on Too close to release Feature developed Bug found! Regression found!

Traditional approach

Developers have moved on

Too close to release

Faster feedback Development Acceptance Testing Regression Testing Release Write test as you go Run them as often as you can Problems are found quickly

Faster feedback

Why Automated? Manual testing is slow, tedious and error-prone Especially for regression Either take long time or less thorough What now? Start again? Regression Testing 3 months

Manual testing is slow, tedious and error-prone

Especially for regression

Consistently Thorough Fast enough to start again and again and again… Regression Testing 10 minutes

Question #2: Continuous Integration

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

Integrates source code and runs tests after each commit of code to the source repository.

Near-immediate feedback to the developer

CruiseControl http://cruisecontrol.sourceforge.net/

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.

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. VCS Build 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, Make 2. Run Build 5. Publish Artifacts 6. Send to publisher 1. Get the latest source 3. Tag source (optional) Project Specific Adapter - Ant Script 4. Run Build

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.
