This course provides an overview of techniques to build correct software, with a strong focus on testing and program analysis. In particular, we will cover topics including:

  • Code documentation
  • Modularity and coupling (Design patterns)
  • Dynamic program analysis (Testing, fuzzing, concolic execution)
  • Static program analysis (Numerical abstract interpretation, pointer analysis, symbolic execution)
  • Formal modeling (Alloy)

Students apply the learned techniques to solve a group project in the area of program analysis.


Note that the modalities described below are subject to change throughout the semester.


  • Lectures will generally be held in-person in HG F 3 and will be recorded.
  • Recordings can be found here.


  • Exercise sheets and corresponding solutions will be published here by Wednesday evening. Please solve the exercises before the next topics's exercise block and before looking at the solutions.
  • Exercise sessions start on Thursday in the first week of the semester (22.02). There will be identical sessions in Thursday-Monday blocks in person. The exercise sessions will consist of a discussion of the solutions of the previous problem sheet, a brief recap of the current week's topics, and a pre-discussion of the next problem sheet.
      • Groups 1 + 2 (Mon 14-16): Physical in IFW A 36
      • Groups 3 + 4 (Thur 16-18): Physical in LFW C 5
  • Exercise sessions will not be recorded.


  • For any additional questions regarding the lectures or exercises, we have prepared a Moodle forum.
