Technology Facts
ROI
Technology
Automation
• Over 73% of applications developed today are web enabled
Tools
applications
• Prevalence of Firefox, IE, Safari and Chrome as the major
browsers, with multiple versions
• Incompatibilities between these browsers primarily due to
javascript implementation
• Testing needs for Web Applications is multiplied due to
permutations of these challenges

Test Automation Facts
ROI
Technology
•
New requirements are introduced on a daily basis
Automation
Tools
•
Testing window is getting smaller day by day
•
Test automation can never replace human testers
•
Not all test can / should be automated
•
Test automation is a supplement to help / boost overall testing
•
Use test automation for area that are least prone to changes
and yet require frequent tests

Myth#1: Test automation is a goal never reached
• Automation is a project on top of our goal list
• Many testers intimidated with test automation
• Developers don’t want to learn test automation
• GUI automation is hard so lets not do automation
• Automate everything and fire the testers
• For some - panacea and others - waste of time
Automation testing is an investment – will take time and effort to bring to fruition

Myth#2: Record / Playback
• Main feature recommended by any test automation
tool vendors
– Capture user actions and later on play them back for
regression testing.
• Simple steps to follow
–
–
–
–
–
Design test case in test automation tool
Use capture feature to record user actions
Enhance script with verification points
Add delay and wait state points for synchronization
Playback and observe results in log file

Record / Playback Myth
• Learning’s
–
–
–
–
–
–
Scripts resulting in hard-coded values
Costs associated with maintenance is astronomical
Scripts are often not reliable (pop-up, messages)
If tester makes a mistake – re-record the script
If application changes – re-record the script
Scripts cannot be recorded until software works
Nothing is ever tested by this approach

Choosing a test automation approach
• Test script modularity
• Test library architecture
• Keyword or table driven testing
• Data driven testing
• Hybrid-Keyword & Data driven both.

•
•
•
Support for Windows, Linux and Mac OS
Supports browsers – Explorer, Firefox, Safire
Supports AJAX calls
Non-developers can develop test cases
Graphical Selenium IDE
Export test cases as JUnit test cases

Looking beyond automation testing
• Test reports are automatically prepared
• Defects are automatically captured in defect tracking system
• Test metrics are updated automatically
• Traceability matrix is updated automatically
• Select test cases automatically based defect status updates
• Calculating code and test coverage automatically
• Suggesting improvements in test coverage
