Testing problems
Too many configura-ons!
Time-‐consuming
Ana B. Sánchez #DrupalcampSpain2015
Testing variability-intensive systems
Test case selection techniques reduce the test space by selecting a portion of the configurations to be tested.

Testing variability-intensive systems
Test case prioritization techniques schedule test cases for execution in an order that attempts to increase their effectiveness at meeting some performance goal.

Testing variability-intensive systems
Artificial models to test
How to evaluate these testing techniques?
Ana B. Sánchez #DrupalcampSpain2015
Towards real highly-configurable tools
Studied Tools
Ana B. Sánchez #DrupalcampSpain2015
Testing of real highly-configurable tools
1. Available code
2. Detailed fault reports
3. Automated test cases
4. Extensive documentation
5. > 630,000 users and developers
6. > 30,000 modules

3.232 Faults in v7.23 160 integration faults:
• 132 caused by 2 modules
• 25 caused by 3 modules

Our proposal: SmarTest
¿What improvements do we add to SimpleTest?
SimpleTest ü Designed to make testing easier
ü A powerful automated testing
ü Selector to select tests to execute
ü Detailed inform. about test execution
ü Possibility to follow the trace of errors
SmarTest ü Customizable Dashboard with run-time extracted data to guide the testing
ü Test prioritization fo detect faults faster
ü Automated testing with feedback in real time
ü Time-out option to automatically stop the test execution
Ana B. Sánchez #DrupalcampSpain2015
Our proposal: SmarTest
Things that we are working on…
• Improve the dashboard with more information and new widgets
• Include new test prioritization criteria and multi-prioritization criteria
• Study the integration of SmarTest with other test systems: Behat, phpUnit…
• Improve the SmartTest UI
• Add the SmarTest to Drupal sandbox
• ¿Any suggestions?
