SQA engineers use test automation software programs which set up test trials and preconditions to examine product functionality, content and user friendliness. Engineers then simulate product performance, evaluate results and compare those results with predicted outcomes. Once the automation process is complete, these professionals identify and document product problems or defects using bug tracking systems. For some applications, engineers might create databases of known defects in order to develop protocol for repeat problems. Finally, these professionals might analyze defects and may either send the product back to developers for modification or may hone the product themselves. Aside from product testing, SQA engineers may also review product requirements and specifications in order to foresee potential issues, provide input of functional requirements and advise on design. Other duties include making suggestions to improve testing strategies, as well as utilizing databases to create reports and presentations on any defects.
