  5. Working hours by person Realised hours in this iteration Final summary

  6. Quality metrics • Unit testing coverage improved, but still limited • 19 classes are tested automatically • System level testing framework available, number of test cases limited • 3 open bugs are actually missing new features, which have been marked as RESOLVED LATER into Bugzilla • CPU usage is not recorded • Epsilon is not fully working • The limits of the model are not binding the solver

  7. Quality assessment Legend Coverage: 0 = nothing 1 = we looked at it 2 = we checked all functions 3 = it’s tested Quality: J = quality is good K = not sure L = quality is bad

  8. Software size in Lines of Code (LOC)

  9. Work practices • Documentation practice • proved to be a good way to ensure readability and consistency of produced material • Meeting practice • lack of regular ”mini-meetings” spoiled communication within project team • Design patterns • provided support to users familiar with the topic • Heuristic evaluation • was used to develop usability of GUI • peer testing was also partly executed as heuristic evaluation of GUI

  10. Work practices (2) • Pair programming • practice was seen as pleasant way of working, but productivity is questionable • was used in most difficult modules, thus comparison between modules is biased • Unit testing • project did not contain maintaining the code and thus unit testing was not seen as useful • test cases were written too late • Automated system-level testing • building the testing framework took too much time • number of test cases remained too small

  11. Tools used • Java, GNU Make, Javadoc, CVS and Bugzilla • ”old faithful” set of tools suitable for any project • Jlex and Cup • tools for handling the lm language • fulfilled their duties as expected • had limitations, but not a problem in this project • Trapoli • basically a moderate tool for time tracking, but had several shortcomings • with better guidance and manuals can be used also in future • maintenance of server needs to be improved

  12. Tools used (2) • OpenOffice.org and Dia • good tools for documentation, especially on Linux • OpenOffice.org can be recommended • Dia had problems with incompatible versions • CCCC, Checkstyle, PMD, FindBugs • tools for evaluating the source code • were not used efficiently • had potential, in larger projects could be used more efficiently • Jetty • library for building Java Servlets • fulfilled our needs and seemed to be a good choice
