In this thesis, software industry testing standards were reviewed to help improve NAPCON Display Viewer 5 (DV5) test coverage. DV5 is the graphical user interface part of the NAPCON Operator Training Simulator (OTS) and has a large existing codebase with no existing testing procedures. To help improve build stability a shallow and wide smoke testing approach would be adopted to cover as much core functionality as possible, before more rigorous end-to-end testing could be implemented. The thesis study was conducted using the design science methodology. As part of this thesis, a smoke testing tool was created to test DV5 display and faceplate opening functionality. DV5 simulator configurations can consist of up to several hundreds of displays and display construction requires a lot of manual work. Using the created tool, tests were conducted in several display repositories to determine the functionality of the display sets. With only shallow automated testing, minor errors were found in most of the tested repositories, demonstrating the usefulness of automated testing with large display sets. In addition to the display testing results the display testing execution helped demonstrate some of the DV5 performance issues. Based on these findings, the smoke testing scenarios could prove useful in the future in DV5 performance testing.
