DESCRIPTION
IMPLEMENTING AUTOMATED TESTING – WORKING SMARTER NOT HARDER Blayn Parkinson, University of York Automated testing frameworks and their use were once the preserve of software developers and specialist companies. These are now becoming more accessible to those of us without such resources at our disposal. Automated testing tools which record the clicks and playback tests are just a plug-in away. These tools have the capability of allowing ‘front end’ testers to record once and repeat tests in a variety of browsers, ultimately speeding up testing and automating repetitive tasks. This presentation documents our journey in developing an experimental approach to upgrade testing (Blackboard Learn 9.1 SP12), and task automation (exporting data from Campus Pack 4), via web browser automation developed at the University of York using Selenium (http://www.seleniumhq.org/).A formal set of pre-upgrade tests, conducted by hand in a variety of supported browsers have traditionally been used at York to validate service pack upgrades.50% of these tests have been automated and can now be run on demand to support change management processes. This has freed up the time of our e-learning support staff to appraise new service pack features and tools, rather than get bogged down in testing. An added benefit has been that the lead times needed to test new service packs have been cut, allowing us to deploy the latest service pack offering. We will outline the evolution of our preparations to managing VLE upgrades, charting the transition from manual to automated functional testing, looking at the challenges of developing and implementing automated testing – the problems encountered at the time along with our assessment of the sustainability of this approach for future upgrade testing. We will describe how automated testing has been deployed to support the transition away from a cloud based blog/wiki service. Development of data driven automated scripts to mass export content has saved time and money and provided a neat solution to reclaiming data hosted off campus.

WHAT WE ARE GOING TO LEARN TODAY
• The benefits of using automated testing strategies.
• Limits to automated testing
• Suggestions on future collaboration in this area
OUR CHALLENGE
Thorough testing cycle ( each software not deployed without testing).
3 months: April – June (One window a year to achieve this).
• Lack of agility in responding to new releases, due to the testing time that we need to devote to a release.
• Needed to lock in to a release at a particular time.• Spread the load across the team in terms of manual testing.
OUR CHALLENGE
Functional testing • is necessary• is time consuming• can be ambiguous

PROS AND CONS
Saved time Maintenance burden
Reusable Human intervention
TAKING THIS FORWARD
• Automate more• Maintenance• Continuous testing• Load testing• Blackboard client assisted testing?
OUR RESULTS
• 50% of tests automated (from 2013 testing cycle)
• 2014 Upgrade locking into SP16
• How much maintenance is needed, BB switch from iframe’s to HTML5 will impact on this.
• Can we extend the current % of automated tests
• Review this summer of complete process
DO THIS NEXT
Think about how the adoption of automated testing processes might benefit your institution.
Jointly (with Blackboard) could we come up with a solution to better help the testing processes within our own institutions.
