The Next Generation Tester: Meeting the Challenges ofa Changing IT World 21 Challenges for testing • A wide range of functional and non-functional quality attributes must be considered, suchas: – Performanceofdataanalysis toprovidebusinesswith“instant” results – Scalability of applications to enable potentially huge volumes of data to be acquiredand integrated into theexistingsystem data – Functionalcorrectnessofanalysismethodsandalgorithmsapplied to thedata • Datacurrency,backupandrecoverycapabilitiesmustbe testedtoensurethehigh quality of data. In many cases this data may represent a “single point of truth” for theentirebusiness. Competencies requiredof theNG Tester: • Providestakeholderswithanassessmentofproductriskswhichconsider thekey qualityattributesofBD applications. • Agree testinggoalswith awidevarietyofbusiness stakeholders. • Conduct exploratory testing sessions with business stakeholders to evaluate the valueandaccuracyof resultsprovidedby theBig Dataapplication. 6.2 TestingApplicationsUsingConnectedDevices Applicationswhichuseconnecteddevices fall into twobroadcategories: • Appswhich runonhand-heldmobiledevicessuchasa smartphone • Applications built on the concept of the “Internet of Things”.

In addition to functionality, these include the following non- functionalcharacteristicsandassociatedanswers tobeprovidedby testing: • Usability: – Can the usereffectivelyandefficientlyuse the application? – Is therea positiveexperiencefor theuser? – Canuserswithdisabilities alsoaccess theapplications? • Performance – Does thesystem respondto user requests ina timelymanner? – Can the systemdealwith the loads imposedbymanyusers?
